 to place some boards across the head of the pond 

 to give shade and shelter to the fry. It will 

 probably be found that if much artificial food is

 the surface of the water. This scum is com- 

 posed of grease, and should be removed, as soon 

 as it is observed, with a gauze net. 



All the time that these operations have been 

 going on with regard to the little fish them- 

 selves, due attention should have been given to 

 the vegetation round the ponds. The alders 

 and willows which I before recommended to be 

 planted round the ponds should be induced as 

 much as possible to overhang the water. Grass 

 and other vegetation should be allowed to grow 

 freely round the margins, as many insects are 

 then likely to fall into the water.

 a certain amount of natural floating food, with-

 culturist ; but he should, however, give them
