212 Mass. 168 | Mass. | 1912
The plaintiff while at work for the defendants suffered personal injuries by the breaking of a derrick boom, and no contention is made as to his due care, or that the verdict on all the evidence was unwarranted, but the defendants ask for a new trial on the ground of alleged errors in the admission of evidence.
At the place of the fracture it was abundantly shown that the inside of the boom was permeated with dry rot, or, as described by the defendants’ superintendent, the wood had become dead but not rotten. The distinction is immaterial. If either rotten or dead, the jury could say that the boom had lost its tensile strength and had become unsound. The jury had before them the evidence of the plaintiff’s mechanical expert, whose qualifications were not questioned, that there was a general custom among contractors to examine second-hand derricks before they were used, to ascertain whether they were rotten, cracked or “ crimped,” by tapping with a hammer or boring with a small bit. If there is rotten or unsound wood the character of the resonance caused by the blow or the appearance of the chips will disclose its condition. When they came to consider the testimony of the only defendant who testified, the jury could have found, that the derrick was purchased from a dealer in second-hand derricks, and, if no inquiry was made as to its age, this defendant knew that after several months use on but one building it had been stored for eight or nine years, and that with knowledge of these circumstances, and relying on such information as could be obtained from visual
The admission in evidence of the price which they paid does not appear to have harmed the defendants as there was no proof of the cost of a new derrick. McGonigle v. Belleisle Co. 186 Mass. 310, 312. Scaplen v. Blanchard, 187 Mass. 73.
Nor was the plaintiff restricted to proof of a single defect in the boom, but could offer evidence of any defective condition which might have caused the accident. Droney v. Doherty, 186 Mass. 205. If it gave way because of a “ crimp ”, described in the evidence as a diseased condition which as it progresses finally cuts the fibre of the wood, the opinion of the expert, that from the nature and appearance of the fractured ends the boom parted from this cause, was clearly admissible. Hand v. Brookline, 126 Mass. 324. It also was shown by this witness, that the “crimp” could have been ascertained by sounding with a hammer, and it was a question for the jury on all the evidence whether the boom broke from either cause, or from both causes, and whether the defendants were chargeable with negligence in failing to discover the defect or defects. Cahill v. New England Telephone & Telegraph Co. 193 Mass. 415, 418.
The evidence showed, that the boom was being used to lift material required in the construction of the building varying from one quarter of a ton to two tons in weight. It probably might have supported safely a lighter burden, and because the jury would be aided by testimony from qualified experts as to its lifting capacity at the time of the accident, opinion evidence as to the sufficiency of the boom for general work of this character was rightly admitted. Prendible v. Connecticut River Manuf. Co. 160 Mass. 131. Lang v. Terry, 163 Mass. 138.
Exceptions overruled.
