The only question made by the plaintiffs in respect to the account is upon the disallowance of their charge of $475 for extra use of the derrick.
The case shows that the plaintiffs were granite tool manufacturers, and tenants of the defendants’ shops under a lease, by the terms of which the plaintiffs were to furnish the defendants with the necessary power, from the plaintiffs’ twelve horse power engine, to run the defendants’ derrick and two grind-stones and shafting for their business of cutting and manufacturing granite.
The defendants had occasion, in the fall of 1890, to erect an extra derrick, and the plaintiffs’ evidence tended to show that the use of power by the defendants in the operation of the extra derrick was much greater than before its erection; that the defendants communicated power to the extra derrick through the old one, and that after the erection of the new derrick, or the attachment to the old one, the latter *499was sometimes used singly, but when in use, power was sometimes communicated through the two derricks. On the other hand the defendants claimed that they used no more power than the plaintiffs were bound to furnish by the terms of the lease, and their evidence tended to show that no more power was used when the two derricks were operated together than was used in the operation of the old derrick, including its use in dragging stone across the yard, which the plaintiffs claimed was improper as not contemplated by the contract.
The question was one of fact, whether or not there was an excessive use of power after the erection of the additional derrick, and it was submitted by the court to the jury under the instruction that the plaintiffs were entitled to recover upon showing an express or an implied promise by the defendants for all the power that was used in operating the derricks as modified by the erection of additional machinery —the second derrick; for what was used in excess of what would have been used if the derrick had not been employed for improper purposes; that the plaintiffs might recover for what power they furnished in excess of what they were required to furnish by the lease. The instructions covered every phase of the case so fár as shown by the exceptions. The testimony of the witness Whitcomb — that in the use of derricks they sometimes had to drag stone in operating a granite yard — became immaterial in view of the fact that the court treated this as an improper use of the derrick.
Judgment affirmed.
