To arrive at the contents of a bin or chest in bushels, mul- 

 tiply the cubic contents by 0*779. 



Corn bins are sometimes marked with a gauge, which gives 

 at a glance their contents in bushels, horizontal lines of paint 

 being drawn at every 5 bushels, with shorter intermediate lines 

 marking the height of every bushel, so that a close approximate 

 of the amount in the bin can be ascertained by levelling the 

 corn to the nearest line of the gauge. 



The fittings for cutting, bruising, and mixing the materials 

 for food, depend on the means which are used for carrying out 

 these operations, and whether manual, horse, or 

 engine power. In stables where only a few horses 

 are kept, the chaff is cut and the corn bruised by 

 manual power only, and is usually passed down 

 into the stable (sometimes into the corn-chest 

 itself) by means of a shoot, which may be made (if 

 desired) as shown on Fig. dZ, with a contrivance 

 after the manner of a shot-belt to measure the exact 

 amount of food required for each horse's meal. 



Where horse-power is employed a large area has 

 to be devoted to the track. At the Portsvvood 

 stables, for instance, shown on Plate 53, Fig. 2, 

 where two horses are employed, an area of 600 

 feet super is occupied. The gear for a single horse, illus- 

 trated by Fig. 69, is for a machine with a 36-inch driving 

 wheel. The pinion shaft revolves at a speed of 7 to i, and by 

 means of a separate intermediate motion to ^2)h to i of the 

 horse. 



Very much preferable as a motive power, where there is 

 sufficient work for a horse, is a small gas engine. At the 

 stabling designed by the Author for 120 horses, and illustrated 

 on Plate 39, a small Crossley gas engine of 3J horse-power, in 

 addition to lifting the water for all purposes to a height of 

 30 feet, was successfully employed in working a hoist for lifting 

 the sacks of corn to the upper floor, a large size chaff-cutter
