44 Mo. App. 488 | Mo. Ct. App. | 1891
This was an action against a railroad company for damages for the burning of certain property by fire communicated by one of its locomotives.
As to the first reason, we observe that not only the plaintiff, but also a large number of other witnesses, testified directly and explicitly as to the nature and
We are equally of opinion that the judge committed no error in excluding the testimony of these witnesses called as experts for the further reason, that the proper foundation was not laid for the admission of their testimony. Whether a witness is an expert, so as to render his opinion competent, is always a preliminary question to be decided by the judge. State v. Cole, 94 N. C. 958 ; Flynt v. Bodenhamer, 80 N. C. 205. In laying this foundation, the usual and proper course is to ask the witness what experience he has ha'd with reference to the matter which is the subject of the inquiry. When the witness has answered this question, or other appropriate questions tending to the same end, it is for the judge, and not for the witness to say, whether the witness is entitled to speak as an expert. This question cannot be decided by the witness in the form of an answer to the question, whether he has had experience enough to enable him to form an opinion upon the particulars as an expert.
Applying this principle to the present case, we find that the first witness tendered by the defendant as an expert was asked this question: “ Have you had sufficient experience to be able to tell the effect of a fire burning over a meadow that has been cut, taking into consideration the character of the season, and the condition in which the grass was at the time of the year, the eighteenth day of August 1 ” To which the witness answered that he had. This was simply calling upon the witness to decide that he was an expert for the purpose of speaking upon the given question.
The same witness was asked this question: “ State whether or not you have had experience, within and during the month of August, by making a personal examination of meadows that have been burned over
Another witness was tendered as an expert by the defendant, and this is the way in which the proper foundation for the introduction of his evidence was sought to be laid : “ State, from your observation and experience, whether in your judgment you could form a fair judgment and opinion, as to what would be the effect of a fire passing over a meadow in August of last year?” This was more strongly open to the objection that it submitted to the witness the question whether or not he was an expert, than were the questions submitted to the preceding witnesses.
Another witness, tendered by the defendant for the same purpose, was interrogated in this way: “State whether or not you have had sufficient- experience in examining meadows that have been burnt over to form an intelligent opinion of what effect a fire passing over a meadow in August, such a season as last year was, would have upon the meadow?” The ruling of the court in excluding this question is supportable for the same reason.
The objection urged against the plaintiff’s instruction is that, while the market value of the hay and grass is ascertainable, that of the hedge fence and roots of the grass cannot be said to have a market value. It is no doubt true that the measure of damages in respect of the destruction of the hedge and meadow is the injury done to the inheritance. White v. Stoner, 18 Mo. App. 540. Compare Bobb v. Granite Co., 41 Mo. App. 642. But the defendant is hardly in a position to complain of this inaccuracy in the plaintiff’s instruction, since the defendant’s instruction contained, in respect of the hedge, the same inaccuracy. That instruction told the jury that the measure of damages was the fair and reasonable market value of the -hay, rails, hedge and stones burned; and yet the hedge cannot be said to have had a “market value ” any more than the meadow or the roots of the grass. And if the one had a market value, the other had in the same sense a market value. A party cannot, on appeal, or error, complain of an error in the trial court which he himself has assisted in propagating. Flowers v. Helm, 29 Mo. 324. One party cannot" be heard to complain of another’s instruction where his own anhounces the same doctrine, although it be erroneous. Reilly v. Railroad, 94 Mo. 600; Thorpe v. Railroad, 89 Mo. 650; Holmes v. Braidwood, 82 Mo. 610; McGonigle v. Daugherty, 71 Mo. 259 ; Smith v. Culligan, 74 Mo. 387; Davis v. Brown, 67 Mo. 313; Whitmore v. Supreme Lodge, 100 Mo. 36.
The judgment will be affirmed. It is so ordered.
