Figure k. Sections of troughs, A A, set tandem. Figure 8. Water (late. 



longer than the combined widths of the hatching troughs, allow- 

 ing four feet for aisle space between each pair of troughs. If 

 only one pair of hatching troughs are to be set up side by side, 

 the combined width of which is 30 inches, make the supply 

 trough 36 inches long. If a second set of troughs are to be set 

 up the supply trough should be 9 ft. 6 inches over all. It should 

 be 10 or 12 inches wide and not less than 10 inches deep. 



Bore the spigot holes 6 inches from the bottom of the trough 

 and see that the centres of all spigot holes are in line. The supply 

 trough should be set perfectly level and then if the spigot holes 

 have been bored to a line, a uniform flow may be expected from 

 each spigot.
