100 FEEDING ANIMALS. 



in figs. 11 and 12. This form was put into the stables 

 of Burrill & Whitman, at Little Falls, N. Y. Fig. 12 

 should represent the hind-feet of the cow as standing near 

 the middle of the grating, instead of the edge, as the tread 

 of the hind-feet is required to press the solid droppings 

 through in winter. Fig. 11 explains itself, except that it 

 may be well to mention that the hinges are made by drill- 

 ing a hole near the ends of the iron joists, and then using 

 a wood-screw eye-bolt to attach the grating to the wooden 

 platform. These gratings are made in sections for two or 

 three cows each. One man can turn them up on the 

 hinges, leaving the manure in the pit below uncovered, and 

 easily shoveled into a wagon to be taken to the field. 

 These sections are placed end to end, and the bars are level 

 and continuous, so that they may be brushed off with a 

 stiff broom as fast as a man can walk.

The next style of this grating is represented by fig. 13, 

 which explains its own construction. The change consists 

 in omitting the legs and angle-iron sill in the rear, and 

 carrying up the wall, on the rear side of the gutter, to 

 a level with the under side of the grating, and allowing 

 the back side of the grating to rest upon a thin timber on 

 the top of the wall.
