ones (100,000 to 200,000 bushels) may be contracted for at half the above time 
limit. As to particulars of most modern machinery, very much may be said. 
In general the grain-cars are run into the elevator and unloaded by means of 
steam-shovels—which are large scoops worked by means of rope tackle and 
a steam winch, the scoops being dragged empty to the ents of the car by hand, 
and then hauled back by steam, thus bringing the grain out in the course of 
afew minutes. The grain falls through an iron grating of about 4-inch mesh, 
designed to catch coarse materials, and to prevent accident, and then goes 
down into the hopper, into which the elevator buckets dip (see Fig. 3). ‘The 
buckets, of which there are a variety of good makes, hold about half-a-bushel, 
and are attached to an endless band, which passes to the top of the elevator; 
here the buckets, turning to begin their downward trip, empty themselves 
into the weighing-bins. These are so constructed as to be under the control 
of one man, who does the weighing. The bookkeeper has his office 
near the weigher, and works in conjunction with him. An automatic 
signal warns the weigher when the weighing-bin is nearly full, and _ he, by 
moving a lever, starts the grain to running into a second duplicate weighing- 
machine, during the filling of which he weighs and records the first, and starts
