the boiler, and measured BY means Of : by
drometer adapted to the tube. The iron
boiler showed 367 cubic feet, and the steel
boiler 33l cubic fest Of the remaining feed
water. Therefore the' water evaporated In
the iron boiler was 712-8e7-326 cubic
feet, or 20 ,065 pounds; snd that 'evsporated
10 the steel boiler Wis 7I2-3SI-3Sf ed6ic
