The largest grain elevator in the world, says the _Nashville American_, is
that just constructed at Newport News under the auspices of the Chesapeake
& Ohio Railway Co. It is 90 ft. wide, 386 ft. long, and about 164 ft. high,
with engine and boiler rooms 40 × 100 ft. and 40 ft. high. In its
construction there were used about 3,000 piles, 100,000 ft. of white-oak
timber, 82,000 cu. ft. of stone, 800,000 brick, 6,000,000 ft. of pine and
spruce lumber, 4,500 kegs of nails, 6 large boilers, 2 large engines, 200
tons of machinery, 20 large hopper-scales, and 17,200 ft. of rubber belts,
from 8 to 48 in. wide and 50 to 1,700 ft. long; in addition, there were
8,000 elevator buckets, and other material. The storage capacity is
1,600,000 bushels, with a receiving capacity of 30,000, and a shipping
capacity of 20,000 bushels per hour.

THE FLOW OF WATER THROUGH TURBINES AND SCREW PROPELLERS.

Literature relating to turbines probably stands unrivaled among all that
concerns questions of hydraulic engineering, not so much in its voluminous
character as in the extent to which purely theoretical writers have ignored
