delivered the opinion of the Court.

The Porto Eican Leaf Tobacco Company appeals from an adverse judgment in an unlawful detainer proceeding and says that the district court erred in refusing to admit as evidence the carbon copy of a letter. Prom the transcript of the evidence we take the following extract:

“Plaintiff. We withdraw the document. We submit as evidence the carbon copy of a letter dated October 20, 1934, addressed to Mr. Moisés Colón, Comerlo, Puerto Rico, prepared under the direction of and duly posted by this attorney.

“Defendant. We object to the admission of this document. It does not appear that the court has been requested to summon Mr. Moisés Colón to whom said letter had been addressed.

“The court. The admission of this document is denied, under section 24 of the Law of Evidence.

“Plaintiff. We take an exception.”

Assuming without holding that the statement of counsel amounted to “proof of the due mailing of the letter” within the meaning of Section 84 of the Law of Evidence, the district judge should have admitted the carbon copy if otherwise unobjectionable. Puig v. Soto, 18 P.R.R. 130, 136. The letter, however, is not before us and in view of the conclusion reached as to other aspects of the case the error herein complained of is not a sufficient ground for reversal.

Other assignments are:

“2. The trial court erred in finding that the conflict of title in the instant case is clear.

“3. The trial court erred in finding that the defendant herein supplied the element of proof necessary to establish a conflict of titles.

“4. The trial court erred in weighing the evidence submitted in the instant case by the defendant.”

In an equitable foreclosure suit brought by the Porto Eican Leaf Tobacco Company against Eafael Cruz and his wife, Juana María Díaz Sánchez, a special master sold to the *293tobacco company 9.33 cuerdas of land “bounding on the North with the Bayamón-Comerío road, and lot belonging* to José Moisés Colón Virella; on the Bast with property of Por-talatina Cruz Rivera; on the Sonth with La Plata River; and on- the West with La Plata River and lands of Jnan Oliveros.” In the unlawful detainer proceeding the tobacco company alleged that Moisés Colón was the owner of a parcel of land within the 9.33 cuerdas described as follows:

“Rural building lot in the Palomas Ward of Comerlo which measures 14.83 meters or 49 feet in front and at the rear, and 18.96 meters or 62 feet inches on each side, these measurements being taken from the very center of the gutter on the south side of the road, with an area of 283.07 square meters, equivalent to seven hundredths of a cuerda, or 3 ares, 7 centiares and 3 milliares, bounded on the North by the Comerío-Bayamón road, on the West, East and South by the remaining estate belonging to Rafael Cruz- Diaz. There is on it a house which is partly a one-story structure with an upper floor at its rear, the main floor being built of wood on a concrete base and roofed with galvanized iron. It measures 7.10 meters in front and 11.50 meters at the rear, including the balcony, and there is annexed to it on the right s*'de at the southeastern end a section intended to be used as a kitchen and a bath-room, built of concrete with galvanized iron roof, which measures approximately 4.90 meters in front by 4.50 meters deep. The ground floor, has the same width as the main building and is about 4 meters deep, being built of reinforced concrete. ’ ’

The tobacco company also alleged that after the commencement of the mortgage foreclosure suit, August 7, 1931, Moisés Colón extended his fence so as to include the parcel now in controversy described in the complaint as follows:

“Parcel of land located in the Palomas Ward of Comerio. It is 46 meters long on its north side and is bounded by the Bayamón-Comerío road; 50 meters long on the South and bounded by the Porto Rican Leaf Tobacco Company; 26.50 meters long on the East and bounded also by the Porto Rican Leaf Tobacco Company, and 26.62 meters long on the West and also bounded by the same Porto Rican Leaf Tobacco Company.”

*294The question is whether defendant’s claim of ownership is so manifestly unsubstantial and untenable as not to demand serious consideration or whether the evidence in support thereof was sufficient to raise a legal issue. It is well settled that conflicting claims as to titles if bona fide can not be tried and determined in an unlawful detainer proceeding. A flimsy pretense will be brushed aside. An apparently bona fide claim supported by evidence sufficient to show some color of right, evidence sufficient to present a genuine question of title, will justify and require a dismissal of the proceeding. We shall not stop to review the decided cases. See judgment of the Supreme Court of Spain of May 12, 1919 (146 Jurisprudencia Civil 281, 288); Segundo González v. Colón, 49 P.R.R. ----; Lippit v. Llanos, 47 P.R.R. 254; Laureano v. Diaz, 48 P.R.R. 684; Brunet v. District Court, 45 P.R.R. 871; Schuck v. Verdejo, 43 P.R.R. 64; Rubert Hnos. v. Hernández, 43 P.R.R. 920; Mojica v. González, 43 P.R.R. 956; Ermita v. Collazo, 41 P.R.R. 594; Heirs of Dávila v. Collazo, 41 P.R.R. 173.

The attorney, Francisco Rodríguez Alverio, mentioned by defendant, Colón, while on the stand, testified: that witness in 1924 lived in New York and in 1925 in Comerlo; that he knows Rafael Cruz and Moisés Colón; that he is practicing his profession in Comerlo; that in 1928 witness leased from Rafael Cruz the property in controversy (sic); that when he went to take possession, Rafael Cruz explained or pointed out to him the landmarks and what was included in the property with the view to indicating the portion covered by the contract of lease and showed him the parcel of land which belonged to Moisés Colón which was enclosed at the time by a barbed wire fence; that the parcel occupied by Moisés Colón was in the parcel leased by witness; that witness had seen it the day of the trial and the day before; that it is the-same property leased by witness from Rafael Cruz; that in 1926, Rafael Cruz did not exhibit any document; that Moisés Colón showed it to witness and hold him that he (Colón) wanted to get all the documents which he (Colón) had delivered to Belisario Boscana, which he had left in the office of Celestino J. Pérez; that Belisario, who was a “curial”, a scrivener, had died about that time; that Beli-sario did not work with Pérez; that witness went to work in the office where Belisario had worked; that witness saw a private document executed by Cruz and Colón concerning a lot, the dimensions of which the witness did not remember; that it was the same lot; that they talked to witness *299about it when witness leased the property which he had for two years; that witness knew the property well; that a surveyor was brought to survey it; that it contained 9.40 cuerdas without counting the property of Moisés Colón: that the river, when it rises, covers certain sandy portions planted to “malojillo”; that when witness leased the property there was a “rejoya”, as it is called in the country, some .40 of a cuerda more or less, planted to “malojillo”', which has entirely disappeared and is under the river; that it was measured when possession of the property was delivered to witness; that now it has not been measured; (on cross examination) that witness returned from the United States in June, 1925, and went to Comerlo in July; that he rented the property in 1928 at $40 a month; that he saw the private document in 1926, one year after going to Comerlo, when he took charge of Colon’s affairs; that witness did nothing-in regard to the document; that Colón instructed witness to get the papers which had been in the possession of Beli-sario; that Colón wanted to have them; that Colón did not instruct him to convert it into a public instrument; that witness went to get the papers in order to deliver them to Colón and in order to ascertain whether the papers belonged to Colón witness had to read them; that witness does not remember the exact date of the private document, whether it was 22 or 23; that it was about that time when witness took charge of Colon’s affairs; that if attorney Celestino J. Pérez drew the instrument number 69, executed in Comerlo on July 17, 1923, witness did not see it; that on the day before the trial the river was not swollen, it was normal, but covered the best part of the property, .40 of a cuerda; that when witness rented the property the river, when normal, did not cover that portion of it.

Eafael Cruz testified that he had been the owner of 9 and some hundredths cuerdas of land in Palomas; that witness sold the property to Moisés Colón because witness had bought two cuerdas, one-half cuerda at a time; that witness *300bought 4 or 5 cuerdas from José Cruz and others and when he bought the first two cuerdas he had ceded a lot there which passed through several hands and came into the possession of Moisés Colón and he wanted to buy that property; that witness does not remember the date — some 16 or 20 years ago; that witness bought in 1921; that it was later than 1916 or 1918, from 1921 to 1923; that Colón was negotiating for the property with José Cruz; that witness had bought two cuerdas from Carmen Eivera and they could not execute a deed of conveyance; that afterwards witness bought the 7 cuerdas; that Colón was negotiating with José Cruz and as witness had bought the two cuerdas he said to Colón: “Look here, Moisés, let me have those two cuer-das” and he was willing to let witness have them only on this condition, and then he said to me: “And if you will let me have a quarter of a cuerda . . . .” that witness gave him the quarter cuerda; that witness did not want to accept anything for this but Colón made him take $50 as a gift; that Belisario Boscana, who died in Comerlo, drew an extrajudicial document and witness agreed to execute a deed of conveyance whenever Colón might desire it; that witness can not say whether this was the land now occupied by Colón; that it was a quarter of a cuerda more or less — it was not measured; (on cross examination) that witness still has his furniture in charge of his brother, Taquito, who occupies the house on the property, some chairs, tables and beds, witness can not name all of the pieces, but he has considerable furniture; that the marshal of the Federal Court was there; that witness told the marshal he could deliver possession if forced to do so and that the question of delivery was pending in the hands of his attorney, Martínez Dávila; that the question is still pending as far as witness is concerned because he has not the money with which to go ahead; that witness does not remember the date of the purchase of the-two cuerdas; that witness first bought two cuerdas, 9 and some hundredths cuerdas in all, first two cuerdas and after-*301wards the rest, a total of 9 and some hundredths cuerdas; that before this was the matter of the sale to Colón, before the negotiation with José Cruz, because witness was to cede him a piece of land adjoining the house; that witness marked off some hundredths, a quarter of a cuerda more or less, that as witness had the two cuerdas, Colón then came to him and then they had a talk; that he then said to witness: “What I am interested in is a quarter of a cuerda more or less”; that witness does not remember the date; that witness had made his brother “Taquito” a present of a lot; that the lot was conveyed to Colón; that the lot has been changing hands and when Colón purchased the house witness was about to cede the lot and execute the deed; that witness sold Colón a lot adjoining a house which stood on a lot that witness had given to his brother and which his brother had^ sold to Juan Longo; that after the cession of the quarter of a cuerda to Colón, witness executed a deed conveying to Colón the lot which had been previously ceded 'and which had been changing hands; that the brother of witness sold it and executed the deed; that when it came into the hands of Colón who bought the house, witness had to execute the deed; that witness believes this was before the cession of the quarter of a cuerda, but does not remember; that at the time of the deal as to the lot it was that Colón began negotiating for the house; that witness did not remember whether or not the transfer of the quarter of a cuerda followed that transaction; that the lot was a gift but Colón made witness accept $50.00; that the $50.00 was not for 'the lot on which the house stood; that witness had ceded it to his brother so many years before and his brother sold first the house; that on executing the deed to this lot witness did not receive any money; because the lot on which the house stood was a gift from witness to his brother and his brother sold the house and was entitled to a deed of conveyance; that the ' house was for a long time unrecorded; that the lot was a gift to to the brother of witness and Colón was purchasing *302from another;, that Colón gave witness $50.00 for the other piece.

The surveyor, who shortly before the trial surveyed the property and made the plat introduced in evidence by plaintiff, testified as a witness for plaintiff to the existence of an old fense of woven wire and barbed wire and to the existence of trees along the boundary lines of the parcel in controversy as well as to the existence of the concrete foundations of what had once been a garage within the inclosure. The testimony for defendant is thus corroborated in a measure bj the testimony of this witness. It is practically uncontradicted by the testimony of any other witness. Taken as a whole and corroborated to some extent by the testimony 'of plaintiff’s surveyor, it was enough to justify the conclusion reached by the district judge if he had no reason to believe from the demeanor of defendant and his witness or other wise that their story had been concocted and committed to memory. In the typewritten record we find no such evidence of mendacity as to require a reversal.

The judgment appealed from must be affirmed.
