 nursery or hatching-trays and carefully drops a

 of meat are at once seized by the fry, and when 

 they have entirely disappeared, another drop is 

 administered ; thus in minute quantities is the 

 minutely divided food given, and when the occu- 

 pants of one compartment are satiated, the same 

 process is repeated with the next. The meat being 

 readily digestible, the young should, from the 

 time of the absorption of the sac to the period at 

 which they are turned into the pond, be fed twice
