delivered the opinion of the court.

On the 10th of September, 1866, J. Young Scammon, of Chicago, Illinois, and Florence A. D. Scammon and Arianna E. Scammon, his daughters, were the owners, of a lot of lfind in Chicago, No. 90 Michigan Avenue, known as “ lot number five (5), in block number eleven (11), in Fort Dearborn Addition to Chicago,” the father being the oAvner in fee of an equal undivided one third part of the lot, and having a tenancy for life *636 ,in the other equal undivided two third parts; and his two daughters’ being each the owner in fee of an equal undivided • one third part, .-subject to such tenancy for life of the father. The lot had descended to the two daughters and a brother of theirs from their mother, subject to the tenancy for life of the ■ father, and he ,had purchased from the son the fee of his equal undivided one third part.

On the day above named, Scammon and his daughters executed to the Connecticut Mutual Life Insurance Company, a córporation of Hartford, Connecticut, a mortgage covering the above lot by the above description, to secure the payment of $30,000, in five years, with semi-annual interest at 8 per cent, per annum, according to the condition of a bond which they . at the same time executed. The bond stated that it was given for an actúal loan of money made by the obligee to the obli-gors on the day of its date.

The mortgage contained the following covenant on the part of the mortgagors: “ And further, that they, their heirs, exe.cutors, and administrators, shall' and will, at all times hereafter, until said principal siim of money, and all arrearages' of interest thereon, shall be fully paid, keep all the-buildings .(outhouses excepted) now situate, or that hereafter may be erected, upon' said premises,. fully insured against loss or damage by fire, in some good and respónsiblé'insurance company or companies (satisfactory to the said joarty of the second part, its successors or assigns, or its or their authorized agent), ip. the fair- insurable, value of such buildings, and will legally • and properly assign and deliver to the said party of the second part, its successors or assigns, each, all, and every, the policies of insurance therefor, as soon as and whenever such insurance •shall be effected, and will also deliver to said party of the Second part, its successors or assigns, or its or their authorized agent, all premium or renewal certificates received for the payment of the premium upon such policy or policies of insurance,, as ,soon as and whenever such certificates shall be- issued; and, in. default of so doing, the said party of the second part, its successors or assigns, at its own or their option,'may effect such insurance in its or their name or names, or otherwise,' and the *637 premium money paid therefor shall be a charge upon said premises, and shall be secured by' this instrument in the same manner as the said principal sum of money above mentioned' is secured, and such premium ■ money shall be paid by said parties of the first part, their heirs and legal representatives, to said party of jdie second part, its successors or assigns, on demand, and may be collected at any and all times after the. same shall have been paid, with interest thereon at. the rate of ten per centum per annum from the time the same shall be advanced, and 'the said party of the second part, its successors or assigns, shall hold each and all such policies of insurance so. received, by assignment or otherwise, as collateral and additional security for said principal sum of money and interest, and shall have the right to collect and receive any and all money and sums of money that may at any time become collectible or receivable upon each, all, and every of such policies, of insurance, and apply the same, when received, in the samé manner, as far as possible, as is hereinafter provided for in case of a sale of said above described premises under the power of sale hereinafter-contained. But nothing herein contained-shall be construed as requiring the said party of the second part, its successors or assigns, to incur any expense, or make any effort, to collect any money that may become due on - any of such policies of insurance; but, if it or they shall elect not to collect the same, they shall make such election within a reasonable time after such money shall become collectible,' and, on demand of said parties of the first part, or ,their legal representatives, shall thereupon forthwith, after making such election not to collect, reassign and deliver such policy or .policies of insurance to said parties of the first part, their -executors, administrators, or assigns.”

In the fall of 1867, by" an arrangement. between Scammon and his daughters, the south one.third part of the lot was conveyed to his appointee by them, in fee, as representing his existing interest in fee in the lot, and the north two.thirds part of the lot was conveyed by him to them as tenants in common, in’fee, as representing their existing interest in fee in the lot, subject, as to such north two thirds part, to the life estate of *638 the father therein. Thereupon, the father and daughters paid or caused to be paid to the mortgagee $10,000, ás a reduction, of the principal of the mortgage, and it released, by deed, from the lien of the mortgage, such south one third of the'lot.,

With the money lent on the mortgage, Scammon erected a ■ building on the north two thirds bf the lot, and thereafter collected for his own use the rents fróm it, and paid the interest '.on the mortgage, and the taxes and the fire insurance premiums. Insurance against fire, covering the building, for $15,000, was effected by Scammon, by a policy issued by. the Liverpool and London and Globe Insurance Company in his name, with a clause making the loss payable to the, mortgagee. The building was destroyed by fire in October, 1811, and, the loss being ¿djusted at a sum greater than $15,000, a draft for $15,000. was drawn at Chicago, by the agents of the fire insurance company there,' on that company, at New York, payable to the order of the mortgagee. The draft was handed to . Scammon, and, at his request, the agent of the mortgagee at ’ Chicago sent it to the mortgagee, at Hartforp, with an appli- , cation from Scammon to have the $15,000 paid to him, to 'em able him to rebuild -the building. ’ Thereupon the following instrument was executed in duplicate by the mortgagee and Scammon, a copy being retained by each:

“.Memorandum of agreement made and entered into this fifth day of January, a.d. 1872, between the Connecticut Mutual Life Insurance Company, a corporation subsisting by the laws of the State of Connecticut, and located and doing business in the city of Hartford, in' the State of Connecticut, of the one part, and J. Yo.ung Scammon, of the city of ChicagQ, in the county of Cook, and State of Illinois, of the other part, Witnesseth: That whereas the'said'party of • the second part did, on the tenth day of September, a.d. 1866, make, execute, and deliver to the said party of the first part á .certain indenture of mortgage, bearing date on that day, on the following-described premises, situate and being in the city of Chicago ■aforesaid, to wit, lot number five (5), in block number eleven (11), in Fort Dearborn Addition to Chicago, for the purpose of securing the payment of the certain bond or obligation of the' *639 said, party of the second part, bearing even date with said mortgage, in the penal sum of sixty thousand dollars, conditioned for the payment to said party of the first part of' the ' sum of thirty thousand ($30,000) dollars on the tenth day of September, a.d. 1811, with interest as therein stated, on which said mortgage has been paid ten thousand dollars of principal; and whereas, the building on said premises,, known as No. 90 Michigan avenue, in said- city of Chicago., was insured in the following company and in. the following amount, to' wit, the Liverpool and London and Globe, in the sum of fifteen thousand dollars,, which said, policy of insurance was held by said party of the first part as collateral security for the payment of said loan, any loss on said policy to be paid to said party of . the first part; and whereas said building has been destroyed by fire and the insurance moneys to be received on said policy or policies are subject to be paid to said party of the first part, . in accordance with the conditions of said mortgage^ and .whereas said party of- the second part desires said party of the first part to permit and suffer said insurance money to be used in and upon said mortgaged premises in the reconstruction of said building or buildings thereon, and said first party'is willing to have said insurance money so used, upon the .terms -and conditions hereinafter set forth, and to assist in the collection . and receipt thereof by said second party from said fire insurance company or companies for the purposes aforesaid : It is, therefore, mutually agreed by and between the parties hereto', • that said party of the first part waives, except as hereinafter • provided, its right to apply on the said indebtedness the moneys ■ that may be received on said policy or policies of insurance, and that any and all such sum or/sums of money as shall be so collected from said fire-insurance company or companies, by either of the parties to this ■ instrument shall be deposited in such bank or banks as shall be selected by the party of the second part and assented to by the said first party, to the. credit and at the risk of said party of the sec'ond-part, to be used in the erection of said building or buildings on said mortgaged premises.

“ That said money shall be paid out and expended in the erec- • *640 lion of said building or buildings, from time to time, on the ■drafts or checks of said party of the second part, countersigned by the said party of the first part, or its duly authorized agent or attorney, until said insurance money is fully expended, as " herein provided, on said mortgaged premises. That said drafts or checks shall be so countersigned upon the presentation thereof to said party of the first part,' its duly authorized, agent _or attorney, together with a certificate of a competent and cred-iblé architect, that the amount of said check or draft, together with all previous checks or drafts drawn or paid out on said account, has been actually expended in and upon said mortgaged premises, in the permanent improvements thereon, and that the work and material for which the amounts so expended have been paid are fully worth such sum. •

' “ If, however, said buildings are being constructed without the supervision of an architect, the affidavit of said party of the second part to said facts may, at the option of said first party, be / received in lieu of said architect’s, certificate. And it is further understood and agreed, that, so soon as said building or buifd-ings shall be in a' situation to be insured, said party of the second part ■ shall cause the same to be insured in some good and ■ responsible insurance company, in the fair insurable value thereof, and assign and deliver the same to - said party of the second part, arid, as soon as said building shall become so "insurable, all the provisions contained in said above-described . mortgage shall apply to said insurance, and said conditions are hereby made a part of this agreement.

“ It is also expressly understood, that any receipt or acknowledgment given by said party of the first part, either alone or jointly with others, to any such insurance company or companies, for the purposes aforesaid of facilitating the collection by said second party of any insurance money intended to be placed back on said mortgaged premises as aforesaid, shall not be construed as a collection of said money by said first party under the conditions of said mortgage, wherein and whereby it is provided that said first party may collect and apply such insurance money upon the indebtedness secured' to be paid thereby, but merely as enabling said second party to collect *641 said insurance moneys. Said moneys are not to be so applied^ and said mortgage shall remain a lien on said mortgaged prem-. ises for the full'amount of the ■ principal mone^ mentioned in said bond, with the interest thereon, as if said moneys had . never been collected.

' “ It. is also further expressly understood and agreed, that said ' insurance money shall be expended on said mortgaged premises as above provided, with all reasonable and proper dispatch and that, in the eyent that, from any cause, whether the death or absence of any party or parties to this agreement, or any other cause,'said money shall not have been so expended within six months from the date hereof, then this agreement of waiver shall thereupon become thenceforth null and of no effect, and the right of said second party to use and expend, said moneys > shall thereupon cease, and said first party, shall have the right' to draw from the said bank or banks, upon its own check or checks, or that of its authorized agent, said insurance moneys, or so much thereof as shall not then have been, actually expended as provided in this agreement, and apply the same in1, payment pro tanto of the indebtedness secured by said mort-' gage, and such check or checks of said first party or its agent as aforesaid, drawn at' any time, after the expiration of six months from the. date hereof, shall. be a- full discharge and acquittance to said bank or banks for any moneys paid thereon.

• “It is expressly agreed, that time shall be of the essence .of this agreement in all its parts, and that said agreement shall be binding upon the heirs, executors, administrators, successors, ■ ■and assign's of the respective parties.”

' . On the, execution of this agreement, the mortgagee endorsed the draft, making it payable to Scammon or his order, and- sent • ’ it to its agent at Chicago; Scammon signed on the agreement • a written designation by him of “ the Marine Company of Chicago,” a banking institution of which he was then president,' as the banking office in which to deposit the $15,000; and the' draft was then delivered by the agent to Scammon, and collected, and its proceeds were deposited to his crédif in thó . Marine Cómpany. . The transaction between Scammon and the agent took place .at the banking company’s office, and the *642 agent exhibited the copy of .the agreement to Scammon, as president of the bank. No checks against the money,were ever countersigned by or on'behalf of the mortgagee, nor was any of it used in putting up any new building on the lot, nor . was any such new building put up. Scammon’s daughters had no knowledge or information as to any part of the transaction between their father and the mortgagee in regard to the $15,000.

Under that state of facts, the mortgagee, in June, 1876,-filed a bill in equity, in the Circuit Court of the United States for the Northern District of Illinois, for the foreclosure of the mortgage, making as' defendants Scammon and the two daughters, and, Reed, the husband of one of them, and other persons. The bill credits the payment of the $10,000, in November, 1876, as one by Scammon and his daughters, in reduction of the principal of the mortgage, and sets forth the release of the south one third of the lot from the lien of the mortgage, but ignores any credit of the $15,000, and claims as due $20,000, with interest at 8 per cent, per annum from September 10, T873, and moneys paid by the mortgagee for taxes and assessments.

Mrs. Reed and her sister answered the bill. The answer sets forth the transaction in regard to the ‘$15,000, and avers that it took place .without the knowledge, authority or consent of the daughters, and that the mortgagee, in consenting to the use of the $15,000 in any other way than in payment of the mortgage indebtedness, relied on the credit of Scammon and released the property of the daughters to that extent. It claims that Scammon’s life estate in the north two thirds part . of the lot should be first sold, and the proceeds be applied first in payment of the remaining $5000 and interest, and the property of the daughters be thereupon released from all further liability.

After issue, the court referred the cause to a master, to take proofs and report them, with the amount due to the plaintiff, lie reported the testimony, and that there was due $20,000 of principal, and interest from September 10, 1873, and certain sums paid by the plaintiff for taxes and assessments, with *643 interest thereon. Mrs. Need and her sister'excepted, to-the report, and the case was heard on the exceptions. The court rendered a decision, 4 F^d. Rep. 263, in which ..it .was ruled, ' (1) that authority in .Scammon, as representing his. daughters, .to malte the speciahagreement in regard tó the $15,000, could not be implied from the general power he" exercised over'the property, in managing it, and procuring insurance and paying taxes, the (laughters haying themselves executed the mortgage; (2) that the insurance was obtained in pursuance of the requirements of the mortgage, and must be presumed to have coveted the interests of-all the mortgagors, as an entirety; (3) that the mortgagee in fact dealt with' the $15,000 not as Scammon’s money, .but as representing a further security furnished under the mortgage, and- as something which concerned the rights of all the mortgagors, because the agreement it made with Scam-mon recognized its obligation either to credit the- $15,000 on thé mortgage or to see that it went to restore the' building; (4) that the provision of the policy, that the loss should be ■payable to the mortgagee, placed it-in the same position towards all the■ mortgagors as if the policy had b¿en.taken out in the names of all, and assigned, to the mortgagee; and it was bound to apply the $15,000, in accordance with the provisions of the mortgage,.- for the benefit of all the mortgagors, unless all consented to. a different disposition of. the money; (5) that, in any vievs;, if the agreement with Scammon was valid, as against the daughters, .the mortgagee was bound' to see that the money was used to restore the building, or else credit -it on the mortgage.

Under these views, the court referred the. case back to the ■ master, with directions to restate the account according to the principles thus laid down.' He did so,. and, the cáse. being heard on his report, the court, .on the 2d of October, 1882, rendered a decree, which, after setting forth the material .-facts’ above stated, contains the following clauses: .

. “ The court further finds, that,, when the complainant origi-. nally took the said mortgage,' it, by its agent, knew; the state of the title of the.mortgaged premises; that, in the erection of the building on said premises, and causing it to be insured, and *644 in collecting rents and paying the insurance premiums and taxes; the defendant S. T. Scammon held the property as if it was his own; that the entire business connected with the loan ■from the complainant, from the time of its original negotiations down to the time of the before-mentioned agreement in relation to the insurance, was transacted by J. Y. Scammon, who kept an account of the property in his bank ledger, in which rents by him received were credited, and the moneys paid out were also' entered ; that the defendants Florence A. D. Reed and Arianna E. Scammon knew nothing, at the time, of the insurance obtained upon the property, nor anything in relation to- the agreement between their father and the complainant made in-1872; that the complainant entered into, the agreement for the payment of the insurance money to Scammon to be by him used in rebuilding, in. good faith; and that said Scammon received it in good faith for that'purpose, and the officers of- the bank where it was deposited understood that the money was deposited there as a special deposit, subject to said agreement.

“ The court further finds, that Florence A. D. Reed and Arianna E. Scammon did not know that this insurance had been effected on the property, or of the payment of premiums thereon, and were never consulted about the disposition .of the insurance money, .and had no knowledge of, and gave no consent to, its payment to their father and its deposit in the bank, and have never asserted any rights in relation thereto until the commencement of this suit.

“ The court further finds, that the ac.ts of Florence A. D. Reed and Arianna E. Scammon were limited to the execution of the bond and mortgage and the making of the agreement for partition ; that said insurance was furnished under the covenants of the mortgage, and pursuant to the requirements thereof, and was an additional security held by the complainant for the payment .of the principal sum and interest secured by said mortgage, and that the covenants in the mortgage for insurance operated as an assignment of the insurance fund, when collected,to the mortgagee ; that the acts of the complainant, its receipt of the-draft for said .insurance'money, and its endorsement *645 thereof to the defendant J. T. Scammon, by ordinary commercial endorsement, and its assumed control- over the ultimate destiny and use of the proceeds thereof,; were equivalent' to a collection of the insurance by the complainant; that the receipt by the,complainant.of said insurance- money operated as a satisfaction pro tanto of- said mortgage, so far as. the estate and interests of the defendants Florence A. D. Keed and Arianna E. Scammon are involved, but that, so far as -the life estate of J. Young Scammon' is concerned, said 'mortgage remains an equitable lien and encumbrance for the full amount

The decree then goes on to declare that there is due, at this date, from Scammon to the plaintiff, on the bond and mortgage, $20,000 of principal and $13,093.32 of interest, as reported, and $1404.44 for interest since the date.of the report; and $3275.42 for moneys, paid for taxes and to redeém from tax sales, and $490.73 for interest thereon, as 'reported, 'and1 $287.51 for interest since the date of the report; being, in all; $38,551.42; that that sum is a valid and first, lienon the estate-of Scammon, for his life, in the north two-thirds of the lot (excepting therefrom a strip from off its north side, .hereinafter mentioned) ; that, of the $38,551.42, Mrs. Need and her sister are personally liable for $5000 of principal, and $3273.33 interest thereon, as reported, and $35.1.11 interest on the $5000 since the date' of the report, ■ and for the above-named sums of $3275.42, $490.73, and $287.51, being in all $12,678.10, which is a'valid and first lien on the estate in remainder of them and each of them, after the expiration of the life estate .of Scammon, in the north two-thirds of the .lot (excepting therefrom the strip above referred to); and that the $12,678.10 is a valid and first lien on said strip. The decree then provides for the sale at public auction of such estate in remainder, excepting the -strip;, and of such life estate, excepting the strip, and of the'strip, each separately; and .directs that the proceeds of the life' estate be applied first to the satisfaction of the amount for- the payment of which the life estate is decreed to -be the sole security, and that no portion of the amount realized from the sale of the life estate shall be applied to pay the costs of the suit, Or. *646 any moneys found due for taxes, or on account of that part of the principal or interest of the bond for which there is other security, until the sum for which the life estate is the sole security shall have been fully paid. From this decree the plaintiff appealed to this court.

The plaintiff • assigns- for error that the Circuit Court erred in giving the daughters credit for the $15,000. But we are of opinion that the views of that court in its decision, as above set forth, and as embodied in the decree, were correct;.

' The policy of insurance was a collateral -security for the joint debt of the mortgagors, furnished in compliance with the provisions ;of. the mortgage, and the mortgagee was bound to apply the insurance money to the payment of the joint debt, according to the terms of the mortgage. In the agreement with Scammon, of January 5, 1872, the mortgagee declares that it held the policy “ as collateral security for the payment ” of the loan secured by the mortgage, and that the $15,000 is subject to be paid to it “ in accordance with the conditions ” of' the mortgage. Although the policy, was taken out in the name of Scammon, it was, under the mortgage, a part of the security covenanted for therein; and must be treated as having been furnished by, and for the benefit, of all the .mortgagors. The insurance was on the building as a whole, and not on any particular interest in it, and- was accepted and treated by the mortgagee as an insurance complying with the terms of the mortgage, and covering all the interests which the mortgage covered.

The mortgagee could not, without the consent of the daughters, surrender the proceeds of the collateral security to Scam-mon, or divert them from the purpose to which the mortgage devoted them. And, in any event, the mortgagee, if at liberty to use the money toward restoring the building, was bound to see that it was so applied, and took the risk of ‘ the diversion. The money not háving been so applied, it must-be credited in favor of the .daughters. Their intention, declared by the mortgage, that the money should be credited on the mortgage^’ was never varied’ by them.

■ Three. persons named Andrews, and the wives of two of *647 them, were defendants-to the bill. It alleged that they had ' interests in the mortgaged lot subordinate to the lien of the' mo'rtgage. They answered the bill, setting up a prior lien in favor of the three, because they had erected a party wall on and along the north line of the lot, under a party-wall agreement made prior to the fnortgage, and of which the mortgagee at all times had notice; and alleging that, if the mortgage was superior in lien, then the residue of the lot,- not dovered bylthe. party, wall, should be first sold to satisfy the mortgage. Issu'e was joined on the answer. In the taking of proofs, the plaintiff put inevidénce a party-wall agreement made June 4, 186.6.,. between Scammon and one Smith,- by which it appears that Smith owned lot 4, next north of lot 5, and gave permission to Scammon to build oné-half of the north wall of a building he was to erect on, lot 5, to the northward of the dividing- line between the two lots, and that Smith, on paying to Scammon one-half of the value of the wall, was to be entitled to use the. north half of it as a party wall. On the 25th of February, 1867, Scammon and his daughters and Smith executed a supplemental paper, stating that the contemplated wall had been erected, and agreeing that such wall was to be considered as built on the dividing line between lots 4 and 5, and that the’ centre of such- wall was such dividing line. There is not,, in the record, any other testimony about any party wall o.r the strip of land, and none' to support the Andrews answer, and " there is no mention of the strip in either of the reports of the master. The ^decree, however, finds that the three Andrews defendants own in fee, subject to the lien of the mortgage, by title derived from Scammon and his two daughters, the strip of land before referred to, describing it as a strip from off the - north sidé of lot 5, 6f inches wide in front, and 9§ inches in . the rear, and the depth of the lot. It also excepts that "strip in declaring that the mortgage is a first lien on the life estate of Scammon in- the north two-thirds of the lot, and in declaring-that it is a first lien on the éstate in remainder of the. daughters therein, and declarés that the $12,678.10 is a valid and .first lien on that strip, and excepts the strip from' the estate in remainder, and from the life estate, in' describing the premises *648 to be sold, and directs it to be sold by itself, after those estates áre sold.

The appellant objects to the adjudication in regard to the strip, i on the ground that there is not in the 'record either pleading, or evidence to support it. This is .true. . The decree must, therefore, be reversed in that respect. It is accordingly

Affirmed, .except as to the strip, and reversed.as to that, and' the case is remanded to the Circuit Court, with a direction to strike out of the decree everything relating to the strip. The costs of the appeal are awarded to the daughters.
