The plaintiff’s intestate was killed while -engaged with one McGrannahan in operating a dump car on the defendants’ quarry. One matter in issue was whether the deceased was so wanting in experience and skill that he was entitled to instructions. It appears that the work of these men *442included the handling of blocks of granite of irregular shape-weighing several tons.
The plaintiff called McGrannahan, and inquired of him. under exception, “You may describe what you saw about Fowlie as to the way in which he did his work? ” and the witness replied, “Well, when we chained a stone he would go round just the wrong way about it.” Plaintiff inquired further, “You may go on with your description of the things you saw him do there— state anything else you observed?” and the witness replied, “Well, in barring stone upon the dump he sometimes put his bar in where it was not required.” This answer was allowed to stand against defendants’ objection that it was not responsive. Nothing further was obtained from the witness regarding Fowlie’s method of chaining or his use of a bar. The court declined to find that the witness was qualified as an expert.
On a former trial, (82 Vt. 230, 12 Atl. 989) this witness: was asked, “You may tell in detail in what way he did his-work?” and answered that he did his work like a man who had never worked about a quarry; and this was held error. The questions asked here were substantially the same'as that one; and the evidence was of the same character, in that it left the matter to stand solely on the opinion of the witness without presenting any facts from which the jury could form its own opinion. But in one respect the evidence is somewhat’different. The answer in the first case covered all the possible duties of the deceased, without indicating a single thing that the witness had in mind, or even that he had anything in mind. Here the witness goes further, and gives two examples of Fowlie’s lack of skill. But the evidence is still nothing more than the opinion of the witness, and its admission cannot be sustained unless the examples given are within some recognized field of opinion evidence.
In considering the subject further it will be sufficient to take up the last statement of the witness, that in barring a stone Fowlie would sometimes put his bar in where it was not required. This is not the description of a mere appearance or movement; as when it is said of the person observed, he looked sick, he walked as if he was tired, he carried the bag as if its contents were heavy. It is not the description of a simple proc*443ess, where the mere statement of the thing done shows the want of experience or skill; as if it were said of a workman that he could not strike with an axe twice in the same place, or that he could not hit a nail on the head with a hammer squarely and consecutively. Here, the question whether the thing done showed skill or the lack of it depended upon the relation of the act to a. variety of conditions. Among these might be the size of the stone, the movement intended to be produced, the manner in which the force was to be applied, the shape and surface of the-stone as affording chances for the required hold, the nature of' the bed on which it lay as affording resistance to the bar, the choice of available opportunities, co-operation in movement with another workman. To make the evidence admissible,— assuming that it was otherwise competent, — it was necessary for the witness to give some of the conditions which made Fowlie’s act improper. The want of this leaves the evidence a matter of opinion without a basis of description. Nothing appears as to what Fowlie did, except that he did something wrong. Whether the thing done really was wrong was left to stand solely on the judgment of the witness.
The plaintiff claims that the answer was responsive, and so not within the exception taken Being no more than the opinion of the witness, it was not responsive to a question which called for description. The question in terms called for description, although it wrongly assumed that the answer previously given was description. But in a long intervening discussion the court had repeatedly confined the inquiry to matter of description, and plaintiff’s counsel had repeatedly stated that that was all he was asking for. The exception taken was sufficient to save the question.
This witness was permitted to testify that a few weeks-before the accident the car gave them trouble by dumping foward. The defendant contends that this was error, because the dumping testified to was in a different direction from that which caused the accident, and because the conditions as regards the track and load may have been different. It appears that the table of the car could be turned on the circle in the frame to permit the duhiping of the load in various directions, and was so'hinged that it could be tilted for that purpose, with connections to-*444.prevent its til ing of its own accord; and appears further that the plaintiff claimed that the construction of the car, its worn -condition, and the length of the restraining chain when hitched .as tightly as the links permitted, were such that the table was liable to tilt of its own accord when the car was in operation. In view of the facts and claims stated, we think the evidence -was admissible.
One Shappy, a witness for the plaintiff, was permitted to ■testify that he had used this car on the old dump before it was Removed to the dump where Fowlie was working; that once while he was using it before its removal the stone “came back” on them, and the car went down the dump. The plaintiff claimed that this car was made out of two other cars of unequal •size, by putting the table of the larger car on the body of the .smaller one, and that the resulting projection was a defect which contributed to the accident. The defendant’s objections to the above evidence were based on the facts that the car had been repaired several times, and that the witness’s knowledge of it was previous to these repairs. But the evidence in question was received in connection with Shappy’s further evidence that he made up this car from parts of two cars as above stated; ■that he examined the car the day Fowlie was killed and used it soon after; and that the only alterations that had been made in the car were such as he described. The evidence received :as above stated was admissible.
In impaneling the jury, the plaintiff was permitted to ask of the jurors generally, against the defendants’ objection and exception, whether any of them “had ever been employed as an agent of an employers liability insurance company.” It does not appear that any preliminary questions bearing upon this matter had been asked, and the inclusion of all the jurors 'in the inquiry indicates that none had been asked.
It has always been held in this State that a party who has the right of peremptory challenge may prepare himself for its exercise by inquiries regarding matters which are not a disqualification. State v. Godfrey, Bray. 170. It is undoubtedly true that the course and extent of an examination on the voir dire is largely within the discretion of the trial court. Quinn v. Halbert, 57 Vt. 178. It is nevertheless a fundamental principle governing *445inquiries by jury that a case shall be tried on knowledge of it obtained in court, and that that knowledge shall be confined to matters pertinent to the issue. This would seem to require that the existence of an immaterial and prejudicial fact should not be suggested to the jurors unnecessarily, either before or during the trial. But a plaintiff is doubtless entitled to put a. question like the one objected to if found essential to his protection, even though prejudicial to the defendant. We are not entirely agreed upon a disposition of the question as presented, and so leave the matter without further discussion.
Objection having been made to something said in argument, by plaintiff’s counsel with reference to the interest that the jury should allow, counsel proceeded to say: “I do not claim that they have got to, but it is within their discretion to allow' such sum as they think would be just, and 1 say it is usually put in the form of interest, though strictly speaking I don’t, understand that it is interest; but it is such a sum as in your sound discretion you think you should allow for not having this-settled when the liability accrued; ’’and upon an exception being asked and allowed counsel added: “That is the law.” However intended, this might easily be taken to mean that the defendants ought to be punished for not settling the plaintiff’s-claim without putting her to the delay and expense of a trial.. The remarks were objectionable; but as the case stands it is* not necessary to consider the incident further.
Judgment reversed and cause remanded*.
