The general statements in the sixth finding, that the owner of.the furnace, after the close of navigation in 1880, continued the manufacture of said ore into pig iron without unreasonable delay,” and on the opening of navigation in 1881 resumed the shipment of. iron to the defendant, “ and continued such manufacture and shipment in cargo lots as rapidly as possible,” are limited and controlled by the more precise statements in the same finding, that if the average- daily product of the fürnace had been the s^me from the close of navigation in 1880 to the opening of navigation in 1881, as it had been during the season of 1880, “ all said 14,000' tons of ore would have been made into pig iron by about' May 10, .1881; but in fact the furnace .was shut down for a time, and part of the time the blast -.was checked, for want of a sufficient supply of charcoal, so that about 1100 tons of said pig. iron were made after May 8,. 1881.”.

After the contract for 8000 tons of pig iron had been partly performed on both sides in 1880, by the • plaintiffs’ having delivered, and the defendant’s having accepted and paid for, 3421 tons of iron, then the thing which, by the terms of so much of the contract as was yet unperformed, the plaintiffs agreed to deliver, and the defendant agreed to take, and pay for, was 4579 tons of pig iron, made and ready for shipment upon the opening of navigation in 1881, and then shipped as rapidly as possible; and the rights,and duties of the parties as to the •performance of this part of the concract were the same as if it had been the whole contract between them.
' The true construction of the contract being that that amount of iron shall be ready to be shipped and be actually shipped as soon as navigation permits, “ that is part of. .the description
