GIANT COAL CONSUMERS.

The records of the great Cunard Atlantic liners, the Lusit&nia and the Mauretania, arc- watched with augmented, interest as time passes.. It is c not <Jenic<l {says the Engineer) that the coal consumption is about 1,000 tons t( every 24 hours. It may be a little r Ic^s or a little more. f The.^b^^icjers [T hold 7,000 tons. How much remains in them at the end of each trip is only . known by a select v few. We take,, it { a for granted, however^ that each ship f burns 1 ,ooojtpji£ I xi' coaL^Kety-24 hours I As ,there , are ,25 boilers,, yeach boiler ;" mju-stf 1 t^ke rpo-tons -per" :dayQ&nd T fhe S same every, .rtighit.
