delivered the opinion of the Court.

On the 20th day of February, 1907, the appellant executed the following guaranty:

“For the purpose of inducing the Irving National Exchange Bank to extend credit to O. S. Norris, their successor or successors, in the form of loans and discounts, a'nd otherwise, and in consideration of the granting of such credit now and hereafter, I, A. E. Booth, do hereby guarantee to the extent of ten thousand dollars, unto the said the Irving National Exchange Bank, its successors, endorsees and assigns, the payment at maturity of every and all sums of money that may become due by the said O. S. Norris, their successor and successors, to the said the Irving National Exchange Bank, its successors, endorsees and assigns, upon every and all obligations of the said O. S. Norris, their successor and successors, direct and indirect, written and verbal, and implied, that may be now and hereafter incurred; and I do hereby consent that the securities of any kind and character that are now and,may hereafter be left with the said the Irving National Exchange *671 Bank, its successors, endorsees or assigns, as collateral to any such obligations, or upon which a lien may exist therefor, may be exchanged, withdrawn or surrendered, from time to time, and that the time of payment of any said obligations may be extended from time to time, without notice to me or assent from me; and 1 do covenant and agree that my liability on tbis guarantee shall be direct, and not conditional upon the pursuit by the said the Irving National Exchange Bank, its successors, endorsees or assigns, of whatsoever remedies it or they may have against the said C. S. Norris, their successor and successors, or the securities or liens that it or they may possess. Dated, Balto., this 20th day of February, 1907. Guaranteed until January 1st, 1909. I

(signed) A. E. Booth,

2532 Eutaw Place, Balto., Md.”

The appellant delivered this guaranty to O. S. Norris, who in turn delivered it to the plaintiff in this case, the appellee on this record.

C. S. Norris was the president of Turle & Skidmore, a corporation, which was engaged in the dried fruit business. That corporation borrowed on August 10th, 1908, from the Irving National Exchange Bank the sum of sixteen hundred dollars, and gave to the bank on that date a demand note for that amount. The note bore the signature of Turle & Skidmore, and C. S. Norris, its president. By endorsement on this note C. S. Norris guaranteed to the Irving National Exchange Bank the prompt payment of the loan when due, and consented that the time of payment of the loan might be extended without notice or further assent from him, and he also waived demand of payment of the note from the maker, and agreed that his liability on tbis guarantee should be direct and immediate, and not contingent or conditional. Payment was demanded of Turle and Skidmore in September, 1908, but tbe note was not paid, except as to tbe sum of six hundred dollars, which the hank permitted O. S. Norris to pay on account. The total amount of the principal and interest due upon this note at tlie time the judgment in this *672 case was entered, was eleven hundred and eighty-two dollars and six cents. Demand was made upon the defendant for payment of the amount due the bank, and he denied any liability under the guaranty.

Suit was brought under the speedy judgment act in the Superior Court of Baltimore City, and the plaintiff tiled with the declaration the note, the guaranty of the defendant and also the guarantee of C. S. Horris to the bank endorsed thereon. As the. defendant by his next succeeding pleading did not deny their execution, they must be admitted for the purpose of the action. * Code, Article 75, section 24, subsection 108; Nicholson v. Snyder, 97 Md. 415; Horner v. Plumley, 97 Md. 271; Commonwealth Bank v. Kirkland, 102 Md. 662.

The case was tried before Judge Gorter without a jury, and judgment was entered for the plaintiff, from which the defendant has appealed.

There would seem to be no difficulty as to the principle to be applied' in the construction of the guaranty. It is said in Miller v. Stewart, 9 Wheaton, 680, that: “Hothing can be clearer, both upon principle and authority, than the doctrine that the liability of a surety is not to be extended, by implication, beyond the tei’ms of his contract. To the extent, and in the manner, and under the circumstances pointed out in his obligation, he is bound, and no further. It is not sufficient that he may sustain no injury by a change in the contract, or that it may even be for his benefit. He has a right to stand upon the very terms of his contract; and if he does not assent to any variation of it, and a variation is made, it is fatal. And Courts of Equity, as well as of law have been in the constant habit of scanning the contracts of sureties with considerable strictness. The class of cases which have been cited at the bar, where persons have been bound for the good conduct of clerks, of merchants, and other persons illustrate that position;” or, as stated by *673 Judge M'cShujuiy in Hooper v. Hooper, 81 Md. 169: “Whilst the undertaking of a guarantor technically differs from that of a surety (Kramph v. Hats, 52 Pa. St. 225), still the contract of guaranty is the obligation of a surety. Davis v. Well, Fargo & Co., 104 U. S. 159. Both are accessory contracts; that of a surety is in some sense conditional; that of a guarantor is strictly so. A guaranty is a secondary, whilst a surety is a primary obligation. A guaranty is a mercantile instrument to be construed according to what is fairly to be presumed to have been the understanding of the parties, without auy strict technical accuracy, but in furtherance of its spirit and liberally to promote the use and convenience of commercial intercourse. It should he given that effect which will best accord with the intention of the parties as manifested by the terms o-f the guaranty, taken in connection -with the subject-matter to which it relates, and neither enlarging the words beyond their natural import in favor of the creditor, nor restricting them in aid of the surety. The circumstances accompanying the whole transaction may be looked to in ascertaining the understanding of the parties. Lee v. Dick, 10 Pet. 482; Mauran v. Bullus, 16 Pet. 528; Bell v. Bruen, 1 How. 169; Davis v. Wells, Fargo & Co., 104 U. S. 159; Mussey v. Rayner, 22 Pick. 228. The contract of a surety must have such a construction given to it 'as will caray out the intention of the parties to it. Englar v. Peoples’ Fire Ins. Co., 46 Md. 333; McShane & Rogers v. Howard Bank, 73 Md. 135, and the contract of a guarantor ought- not to he interpreted by any different rule.”

There is evidence iu the record that the plaintiff accepted Ihe note of Turle and Skidmore and loaned the money on the faith of the guaranty. Mr. Ward, the cashier of the plaintiff, said, referring to the loan, “the credit in this case was extended upon the responsibility of O. S. Horans, as backed up by the guarantee of Alfred E. Booth,” and the record states that the plaintiff “acting on the faith of this guarantee” loaned the sum of sixteen hundred dollars to Turle and Skidmore. Both Turle and.Skidmore and C S. *674 Norris are indebted, to the bank, — the corporation on the note and O. S. Norris ujxon the guaranty endorsed upon the note. The terms of the guaranty signed by the defendant are broad and comprehensive. It was given for the purpose of inducing the plaintiff to extend credit to Norris, and as credit was extended to him under the circumstances stated in the record whereby he became in August, 1908, within the period" limited by the guaranty indebted to the bank, there would seem to be no doubt that the indebtedness sued for in this case is covered by and is within the terms of the guax*anty, and, as credit was given to Turle and Skidmore upon the faith of the guaranty, it “would seexn equally clear that the-plaintiff was exxtitled to the judgment, unless the evidence shows that it had done soxne act or omitted some duty which would bar a recovery.

The acts or omissions of the plaintiff which, it is argued, defeat a recovery are first, that payment of said note was not demanded within the time limit of the guaraxitee. to wit, January 1st, 1909; secoxxd, the extensioxx of the time of payment beyond January 1st, 1909; third, because the proceeds •of the note were placed to the credit of Turle and Skidmoi’e, •and not to the credit of C. S. Norris. These contentions are presented by the defendant’s first axxd second prayers which the Court rejected. Another objection is that no notice of ¡acceptance of the guaranty was given the defendant.

As to the first objection it is sufficient to say that the •guaranty is an absolute one. By it the defexxdaxxt ixi express terms agreed that his liability should- be direct and not conditional, and, therefore, under the settled law of this State notice of the principal’s default or demand upon the defendant was not necessary.

In Heyman v. Dooley, 77 Md. 162, the Court said: “In the case of an absolute guaranty, however, there is no condition annexed to the contract itself, nor is any condition ixxxplied bv law, requiring the guarantee to notify the guarantor of the default of the principal. On the contrary, his liability is governed by the same rules of law by which *675 the ordinary liability of one who has broken his contract is determined. And this being so, if one guarantees in absolute terms the performance of a specific act or contract of another, his liability being commensurate with that of the principal, whatever proof is necessary to support an action against the principal will be sufficient in an action against the guarantor. And as demand upon the principal is not necessary to support an action against him for a breach of his contract, it is not necessary to allege or prove notice of demand upon and default of the principal to charge the guarantor. Having guaranteed absolutely and unconditionally that another shall perform a certain specific contract he must, at his peril, see that the contract is performed. The guarantee must know, it is true, of the default of the principal, and this default may he unknown to the guarantor. But it. is not a fact which lies within the exclusion or peculiar knowledge of the guarantee. On the contrary, it is a fact in regard to which the guarantor had the easy and accessible moans of information, either hv inquiry of the guarantee^ or of the principal himself. And having undertaken that the specific contract shall he performed, and the guarantee having accepted and acted upon the faith of the undertaking, it is the duty of the guarantor to see that the contract has been performed; and this being so, there is no obligation, legal or moral on the part of the guarantee to inform the guarantor of the fact which the latter having means of knowledge was hound to know. And such is the well settled rule of the common Jaw.”

Even in cases' where notice is necessary failure to give notice* to the guarantor of the default of the principal tvould operate to release him from such loss only as he sustained by reason of that failure. Donnelly v. Newbold, 94 Md. 220. In this case there is no evidence that the defendant sustained any loss because of the want of such notice.

There was no binding agreement between the bank and Norris by which the time of payment was extended. ' The bank merely allowed Norris to make monthly payments on *676 account. Mere delay or promise of delay, without consideration, is not sufficient to discharge the guarantor. There must be a binding agreement.

Morris was told that he might send any money he chose to be applied on account of the note, but there was no agreement with him on the subject. Mr. Ward testified that ho refused to give Morris any extensioii whatever on the indebtedness, but told him that anything he sent to the bank would be credited on the note.. It would seem to be utterly immaterial what disposition was made of the.proceeds of the note, and as the loan was made upon the faith of the guaranty and the credit extended “upon the responsibility of O. S. Moitís, and backed up by the guarantee of Alfred E. Booth,” the fact that it ivas credited to the account of Turle and Skidmore can not avail the defendant.

Mor was the plaintiff under an obligation to notify the guarantor that the guaranty had been accepted. Where the guaranty is absolute no notice of its acceptance is necessary. Caton v. Shaw and Tiffany, 2 H. & G. 14; Hutton v. Padgett, 26 Md. 231; Boyd v. Snyder, 49 Md. 325.

It follows from what we have said that there was no reversible error in the plaintiff’s first prayer. That prayer prayed the Court to rule as a matter of law that if the Court, sitting as a jury, found that the plaintiff loaned the sum of $1,600.00 on the promissory note dated August 10th, 1008, introduced in evidence, subsequent to and upon the faith of the guarantee of A. E. Booth introduced in evidence, and if the Court, sitting as a jury, further found that the payment of said note was demanded, and the said note was not paid, and that there became due by the said C. S. Morris upon said promissory note to the plaintiff the sum of $1,600.00, which has never been paid, except to the extent of the payment referred to in the evidence, then the verdict of the Court, sitting as a jury, must be for the balance found to be due from the said C. S. Morris; provided the Court, sitting* as a jury, found that there was no extension of time given by the plaintiff for the .payment of the indebtedness. *677 This prayer stated an hypothesis of fact which, if found to l)e 1nio, entitled the plaintiff to recover.

'Fhe second prayer asserted that under the pleadings the signature of the defendant to the guaranty sued on was admitted. This prayer was properly granted for the reasons above stated.

The defendant’s first and third prayers, which are based upon principles of law not applicable to cases of absolute guarantees, wore properly refused. We have discussed the theory upon which these prayers were presented.

The defendant’s third prayer seeks to prevent a recovery on 1lie ground of variance. It is argued that inasmuch as the declaration alleges that Horris endorsed the note of Turle mul Skidmore to the hank and as the proof shows he guaranteed the payment of the note, there is a real and substantial variance.

As we have stated, the defendant’s guaranty, the promissory note and the guarantee of C. S. Horris to the hank wore filed with the declaration. The defendant was thereby fully advised as to the cause of action, and fully protected from another recovery upon the same cause of action. Again, ihei e is no variance as respects the guaranty sued on. That is the real cause of action, and the alleged variance is merely in a description of the nature of the act by which Horris became obligated to the hank. Under these circumstances 1here was no substantial variance and the prayer was properly refused. Cook v. Gill, 83 Md. 177; Borden Mining Campany v. Barry, 17 Md. 419.

It. may be well to say that theme is no evidence whatever as to when, by whom, or under what circumstances the words "guaranteed until January 1st, 1909” were written in the guaranty. The defendant offered no evidence, and no explanation of this limitation appears in the record..

Judgment affirmed, with costs above and below.
