Thе jury by its verdict found both defendants guilty of burglary in the second degree. After denying their motions for a new trial, in arrest of judgment and for probation, the court pronounced its judgment, sentencing them to imprisonment at San Quentin for the term prescribed by law. Both defendants appealed, claiming that the district attorney was guilty of prejudicial misconduct in his interrogation of prospective jurors and in his closing argument, and *145 that the court erred in its instructions as to the kind of structure that could be burglarized, in its admission of evidence of other crimes and in its curtailment of the cross-examination of the prinсipal witness for the prosecution. Since they do not question the sufficiency of the evidence to support the verdict, it will be unnecessary to set forth all the evidence, but it will suffice to state merely such portion thereof as is required to fully consider the assigned errors. By so doing attеntion will be concentrated upon the controverted issues without any danger of distraction therefrom by digression into undisputed matters.
Defendants contend that the district attorney committed reversible error in asking each of seventeen prospective jurors on voir dire whether he or she belonged to the communist party, and in stating, in response to the court’s query as to the materiality of such question, that communism was involved in the ease. They argue that thereby the district attorney insinuated that they were communists and that such insinuation so prejudiced the jury against them that they were reаlly convicted for their supposed political beliefs rather than for the crime charged. However, the court repeatedly on its own motion and at defendants’ request admonished the jurors that such question concerned their qualifications only, and that, if chosen, they were not to consider it as evidence in the ease. It must be assumed that this admonition was obeyed. Defendants’ attorneys also asked most of the jurors whether such question created any prejudice against their clients and whether each would try the case impartially and solely upon the evidеnce adduced. The answers to these last questions clearly show that no juror was misled by the district attorney’s question into believing he could properly consider communism as an issue. No claim is made that the question of defendants’ guilt or innocence was close. It would appear therefore that the interrogation, even if erroneous, was not prejudicial.
But it does not appear that the interrogation was improper. The prosecution and the defense were both entitled to a trial by fair, impartial and unbiased jurors and, in order to ascertain the existеnce of a disqualifying partiality or prejudice, had the right to examine each juror as to his state of mind in reference to the case. In the background there appears a strike involving a union, of which defendants
*146
were members, and a large oil corporation. The possеssion by a juror of a prejudice against either party to the strike might easily have caused him to return a verdict which would reflect such prejudice. Properly both parties fully examined the jurors as to any financial interest in the corporation or friendship with its officers. They also inquired whether a juror or any relative was a member of a union and what feeling and attitude each had toward a striking union and the employer. In view of the well-known tenets of communists as to industrial strife, the question asked by the district attorney is akin to the other questions, and was proper.

v.
Fitzgerald,
14 Cal. App. (2d) 180 [
Towards the end of his lengthy closing argument, the district attorney remarked that everyone knew that a communist believed in direct action; that he had asked the question as to membership in the communist party on
voir dire
because he did not wish communists on a jury in this type of case and that the evidence showed some communism in the activities described. Defense counsel assigned these remarks as misconduct but did not ask for any admonition. However, the court voluntarily instructed the jury that there was no evidence as to communism and that they were limited in their deliberations to the evidence. It is evident from what was said at the time of these remarks that the district attorney was replying to an argument of defense counsel. The record does not contain the latter argument as required by the rules, and therefore the vаlidity of defendants’ assignment of error cannot be determined.

v.
Bragdon,
Defendants contend “that the court erred in failing to properly instruct the jury as to what constitutes a house, building or structure that could be broken into for the purpose of committing theft, so as to constitute burglary”. Section 459 of the Penal Code defines burglary as follows: “Every person who enters any
house
... or other
building
. . . , with intent to commit grand or petit larceny ... is guilty of burglary.” (Italics ours.) The pertinent part of the indictment charged that the defendants “did wilfully, unlawfully and feloniously enter the
house
and
building
of the Daniels Construction Company, more particularly described as being a
powder magazine
approximately six feet six inches in height, seven feet in width and thirty-six feet in length, having walls of rock, wooden planking flooring, and a doоr six feet high and three inches thick, said door being composed of steel and wood”. (Italics ours.) The com
*148
pany’s superintendent, in describing the powder magazine, testified that it was an excavation dug out of a hill, approximately 30 or 35 feet in depth, 6 feet in width and 6% feet in height; that the floоr was wooden planking, laid on dirt; that the rear, side walls and roof were formed of natural earth and rock, with some planks overhead to prevent a cave-in ; and that the door did not constitute the entire front wall, as there was a little space between its edge and the side wаlls. The court gave the following instruction: “A house, in the sense of the statute, is any structure which has walls on all sides, is covered by a roof, and is used to house or protect persons and their property from the elements or other dangers, and if it has these characteristics, it is none the less a house merely by virtue of the fact its walls and roof may be produced by an excavation in the hillside.” It refused to give, as requested by defendants, the following instruction: “I charge you that the so-called ‘magazine’ that has been referred to in the testimony is not such a structure as can be subjеct to the crime of burglary under the law of the State of California, and you should return a verdict of not guilty as to the defendants.” Since there is no, dispute as to the characteristics of the powder magazine, whether or not it was a house or building is purely a legal question.

Defendants further assert that the court erred in permitting the prosecution to prove that on the night of the burglary dynamite and fuses were also stolen from a locker-box in the vicinity of the powder magazine, аnd that subsequently the defendants had possession of the dynamite and fuses at various places.

v.
McGill,
The defendants lastly complain that the court erroneously would not permit them to attack the credibility of the principаl prosecution witness by cross-examining her as to her true name and assumed- names, and as to her illicit cohabitation with a certain man. A witness may not be impeached by evidence of particular wrongful acts other than a conviction for a felony. (Code Civ. Proc., see. 2051.) It follоws therefore that a witness may not be impeached by
*151
showing the assumption of a fictitious name or specific acts of unchastity. (27 Cal. Jur. 133.) Therefore the court correctly denied cross-examination as to such matters.
