This was a prosecution by the State against appellant, charging him and another, in an indictment, with the crime of arson, in setting fire to a certain store building. The appellant was tried separately and convicted. After overruling a motion for a new trial judgment was entered by the court. From this judgment an appeal was prayed to this court, and by the assignment of errors appellant avers that the court erred in overruling his motion for a new trial. Ninety-two alleged errors are set out in this motion, many of which are waived by failure of appellant to refer to them in his brief.
*3The errors complained of most seriously are, allowing the State to prove the circumstances of another fire in a store owned by-appellant and his father-in-law some five years previous; admitting proof of a fire in Chicago, in the residence of Ben Pink, the person jointly charged with appellant in this indictment, and at a time when Pink and appellant were not even acquainted with each other; permitting witnesses to testify that Pink, after the time of the alleged commission of the offense, had admitted that Pink’s name on a certain card was his signature; permitting experts to testify that the signature of Ben Pranklin on the hotel register was the same handwriting as the signature of Ben Pink on the card; refusing to allow the expert witness for the defense to give his reasons why the signature on the card and the one on the hotel register were not the same handwriting; the giving of an instruction to the effect that the jury might take into consideration the fact that Pink had a fire in Chicago, in determining whether the fire in question was of incendiary origin; the giving of an instruction to the effect that the jury might consider the fire which occurred some five years before, in the store of appellant and his father-in-law in determining whether appellant was guilty of the crime charged; the giving of an instruction to the effect that admissions made by appellant were presumed as a matter of law, to be true and refusal to give certain instructions tendered by appellant,- *

*3Other crimes than the one for which the defendant is upon 'trial are never permitted to be shown to prove the corpus delicti. It is only permissible in the trial of a criminal charge, in those eases where the act constituting the crime under investigation has been clearly established and the motive, intent or guilty knowledge of the defendant is an issue. 1 Wigmore, Evidence §§302-354; Eacock v. State (1907), 169 Ind. 488, 493, 82 N. E. 1039; People v. Molineux (1901), 168 N. Y. 264, 61 N. E. 286, 62 L. R. A. 193. Before the proof of other fires is admissible *4it must be established that the previous fire was ineendiary, and then only after evidence has been introduced showing that the defendant set the fire in question. 1 Wigmore, Evidence §354. It is not easy to conceive how such evidence is admissible at all, in this class of eases, for the reason that if the State has established the fact that the defendant set the fire in question, the intent will be inferred from the act itself; and it would not aid the jury in determining the guilt of the defendant, as to the particular crime charged, to show that he had committed other similar crimes. This kind of evidence is only admissible in that class of eases where the act constituting crime is susceptible of both an innocent and a guilty interpretation; and the question is whether it was done with knowledge, malice or intent. It would be extending the rule too far to allow proof of another fire not connected in any way with the one under consideration, and not shown to be of incendiary origin, and then base a presumption of guilt of the crime charged on the presumption that he had set a previous fire. The court in this case permitted the State to show that appellant had another fire some five years before, as evidence of guilty knowledge of the fire in question without any positive proof that the former fire had been set by the appellant. This was error. Strong v. State (1882), 86 Ind. 208, 44 Am. Rep. 292; People v. Kennedy (1865), 32 N. Y. 141; Bursall v. State (1871), 35 Ind. 460; Todd v. State (1869), 31 Ind. 514.

Appellant complains that the court permitted proof of a fire in the home of his codefendant, Pink, in Chicago at a . •-'•vtime when Pink and appellant were not acquainted and of which it is not pretended appellant had any knowledge whatever. This class of evidence is not admissible against the party on trial where no general conspiracy to set fires is alleged or established by the evidence. State v. Osborne (1909), 54 Or. 289, 103 Pac. 62, 20 Ann. *5Cas. 627; State v. Allen (1906), 34 Mont. 403, 87 Pac. 177; Dwiggers v. United States (1907), 7 Ind. T. 752, 104 S. W. 1166; State v. Spaulding (1848), 19 Conn. 233, 48 Am. Dec. 158; State v. Crofford (1903), 121 Iowa 395, 96 N. W. 889; Swan v. Commonwealth (1883), 104 Pa. St. 218. Conspiracy must first be shown to exist before the acts of the coeonspirators are admissible, and then only such acts as are done in furtherance of the conspiracy. Sanderson v. State (1907), 169 Ind. 301, 82 N. E. 525; Williams v. State (1874), 47 Ind. 568; Card v. State (1887), 109 Ind. 415, 9 N. E. 591; Walls v. State (1890), 125 Ind. 400, 25 N. E. 457; Ford v. State (1887), 112 Ind. 373, 14 N. E. 241. The court erred in admitting the testimony in relation to the Pink fire in Chicago.

It is urged by appellant that the court erred in permitting certain witnesses to give a conversation had with Ben Pink some months after the fire in question, in the absence of the appellant, and out of his presence and hearing, in which Pink made certain declarations and admissions, as to his name and as to his signature on a certain card, which card was afterwards used by expert witnesses in comparing the signature with the handwriting of a name on the register of a hotel, and which was introduced for the purpose of showing that Ben Pink was in South Bend on the night of the fire in question. This was error. Statements or admissions of coconspirators subsequent to the commission of an offense at a time when the conspiracy is ended or the offense committed for which the conspiracy was formed are not admissible against the defendant on trial. Walls v. State, supra; O’Neil v. State (1873), 42 Ind. 346; Dean v. State (1892), 130 Ind. 237, 29 N. E. 911; 4 Elliott, Evidence §§2943, 2944; 12 Cyc. 439, note 14; Baker v. State (1910), 174 Ind. 708, 713, 93 N. E. 14 and cases cited.

*5The card on which the signature admitted by Pink to be his own was also admitted in evidence, and this compared with the signature on the hotel register by the expert *6witnesses for the State who testified they were in the same handwriting. This was error. The comparison by experts must be confined to papers in the case, which the party is estopped to deny, and such others as are admitted to be genuine by the party against whom they are offered. Williams v. State (1911), 175 Ind. 93, 97, 93 N. E. 448, and cases.cited.

Appellant complains that the court erred in instructing the jury that it might take into consideration the fire of one Fink in Chicago as evidence that the fire in question was intentionally set. There is no allegation in the indictment that there was a general conspiracy to set fires, and further there is no evidence that at the time of the Fink fire in Chicago, that Fink and appellant knew each other, or had formed any conspiracy to set fires, nor does the State contend that Fink and appellant did fire any other buildings than the one for which appellant stands charged. The giving of this instruction was error.
As it is apparent that this judgment must be reversed on the errors already mentioned it will not be necessary to further extend this opinion. The other errors complained of may not occur on another trial. Judgment reversed with instructions to sustain appellant’s motion for a new trial.
