345 N.E.2d 841 (1976)
Oscar Maynard ARTHUR, Appellant (Defendant below),
v.
STATE of Indiana, Appellee (Plaintiff below).
No. 475S103.
Supreme Court of Indiana.
May 3, 1976.
Ferd Samper, Jr., Grant W. Hawkins, Samper, Samper, Thoms & Hawkins, Indianapolis, for appellant.
Theodore L. Sendak, Atty. Gen., Susan J. Davis, Deputy Atty. Gen., Indianapolis, for appellee.
PRENTICE, Justice.
Defendant (Appellant) was convicted of murder in the first degree.[1] His appeal to this Court presents two issues.
(1) The number of peremptory challenges to prospective jurors to which he was entitled under the charge.
(2) His entitlement to a mistrial by reason of the court's having permitted the impaneled jury to separate without having given it the admonition required by statute.[2]


*842 ISSUE I.
Defendant was permitted only ten peremptory challenges to the jurors and contends that he was entitled to twenty under the following statute. Ind. Code § 35-1-30-2 (Burns 1975).
In prosecutions for capital offenses, the defendant may challenge, peremptorily, twenty (20) jurors; in prosecutions for offenses punishable by imprisonment in the state prison, ten (10) jurors; in other prosecutions, three (3) jurors. When several defendants are tried together, they must join in their challenges. (Acts 1905, ch. 169, § 228, p. 584.)
It is defendant's contention that he was charged with a capital offense and therefore entitled to twenty challenges. His contention was directly answered by this Court in Martin v. State, (1974) Ind., 314 N.E.2d 60, reh. den. 317 N.E.2d 430.
In Adams v. State, (1972) 259 Ind. 164, 284 N.E.2d 757, this Court recognized that the provision for the penalty of death for murder in the first degree was unenforceable under Furman v. Georgia, (1972) 408 U.S. 238, 92 S.Ct. 2726, 33 L.Ed.2d 346. In the light of those decisions we held in Martin v. State, supra, that it was the nature of the penalty rather than the nature of the crime charged that entitled an accused to an increased number of peremptory challenges. It was there said "* * * It is clear that the capital nature of the punishment calls for an increase in the challenges, and where there would be no possibility of the imposition of that penalty, but only `imprisonment in the state prison' as in this case, the Legislature intended to afford defendants ten peremptory challenges." Although Martin v. State had not yet been decided on October 24, 1972, the date the defendant was refused his requested additional peremptory challenges, Furman v. Georgia, supra, and Adams v. State, supra, had been handed down and controlled the matter in the case at bar as it did in Martin v. State, supra.

ISSUE II.
Immediately after the jury had been sworn and prior to any other proceedings in the trial, the court recessed for lunch and erroneously permitted the jury to separate without giving the admonition required by the aforementioned statute. Immediately upon reconvening, the defendant moved for a mistrial by reason of said error, and the motion was denied.
Although the terms of the statute are mandatory, no error was preserved for appeal, inasmuch as no objection was interposed at the time of the action complained of. Brown v. State, (1964) 245 Ind. 604, 201 N.E.2d 281; Crocker v. Hoffman, (1874) 48 Ind. 207.
We find no reversible error, and the judgment of the trial court is affirmed.
GIVAN, C.J., and ARTERBURN, DeBRULER and HUNTER, JJ., concur.
