 tained by planting them are most satisfactory.

 In this article, I shall only give the details for procuring 

 and hatching trout eggs, receiving the eggs in the form of

 subject of rearing to fingerlings belongs to another chapter, 

 when the fish require more water, more critical care and at a 

 season when farm work demands more attention. 



WATER SUPPLY. 



This is the most important question to be considered both 

 as to quantity and quality. If a hatchery is to be constructed, the 

 water supply is the first consideration and the location of the
