 the next year, so that the raceway can have the 

 full benefit of light and air in order to fulfil one 

 of its functions, namely, that of aeration.

 equipped trout-hatchery will possess all the 

 usual implements for digging, hauling, and out-

 picks, scoops, wheelbarrows, wagons and carts, 

 a roller, mason's implements, carpenter's tools,

 for regular surveyor's instruments. Other
