The invention of an instrument that will, on inspection,show accurately the amount of water evaporated during any given time—as, for instance, during a voy-age—by a steam-boiler, is a desideratum which has long been sought The water-gage represented in Figs. 3769 and 8770 is the invention of William It. Lindsay, con-Btructing-engineer, Now York, who has, after a large outlay of time and money, succeeded in producinga durable and critically accurate instrument, and is the only one yet brought into practical operationwhich can lay claim to that title. It lias been subjected to the most thorough and repeated trials, un-der the supervision of many of out most distinguished engineers, and a board of officers appointed bj theNavy Department to examine and report upon its merits. The trials took place after it had been in 8H8 WATER-METRE. operation more or less every day for the previous five months. On measuring accurately the quantityof water passed through it, in the tanks that received it, and comparing the amount as indicated by theinstrument, the difference on nine experimental trials, under different or varying circumstances, wa
