large number of eggs. Experimenters will find that after 

 preparing suitable beds of sand and small gravel the eggs 

 can be evenly laid and held until covered if the surface of 

 the bed is first thickly indented with cells a little deeper than 

 the eggs. This can readily be accomplished by stamping 

 the bed with a board covered with projections or pegs of 

 suitable size. 



My experiments suggest that in the near future most of 

 the buildings and hatching apparatus now used in the pro- 

 pagation of salmon and trout will be dispensed with ; that 

 after the eggs have been expressed and fertilized, instead 

 of being placed in wire baskets in hatcheries, they will be 

 buried beneath the sand and gravel of the beds of natural 

 or prepared streams, and that with the exception of watch- 

 men to protect them little or no other labor will be required.
