22 Colcord^s System of 



the bottom projecting i^ inches all around, 

 securely nailed on, will hold enough to feed 

 25 head of cattle. Being in constant use, it 

 should be well ironed all around the top and 

 down the ends, at the sides, and securely fast- 

 ened together by ^ iron rods, with nuts upon 

 each end, three of them across each end, going 

 through irons on the outside. This box is 

 suspended (see cut, p. 24) on a y 2 ton compen- 

 sated chain hoist by a chain on each side of 

 the box, with a ring in the centre, the ends 

 of the chains going through the eye of an iron 

 at the top of the box, the other end of the 

 iron being fastened to the 3/& rod running 

 across the outside ends of the box in the 

 centre ; also, by bolts near the chain, so that 

 the chains will be in line from the ring in the 

 centre to the 3/% r ds supporting the box from 

 the four corners at the centre, the rings in the 

 centre being hooked to the chain hoist. 



An iron axle, with wheels 6^4 inches in 

 diameter, is securely fastened across the bottom 

 of the box, 22 inches from one end; the wheels 

 have i y 2 inch tread, and run close to the box, 

 and have a wooden shield to protect them from 

 the chain. The other end of the box should 

 be run upon a good strong castor in the centre. 

 This will enable the box to turn and run in 

 any direction from the silo to every cow.
