hydrometer was used for testing the specific gravity of the solu- 
tion; in that of February 2, a specific gravity scale furnished by 
the Department was used. 
“Hxperiment No. 1. A solution of 1 part salt to 9 parts 
water was placed in a tub, the hydrometer reading 44; 20,000 
salmon eggs, good and bad, were placed in the solution, and at 
the end of two minutes about 66 per cent of the bad eggs floated 
at the top and were removed with a scaff net, 34 per cent sinking 
to the bottom with the good eggs. A few good eggs floated at the 
top with the bad eggs. After remaining in the solution the eggs 
were removed to running water. ‘They were then well washed 
and again placed in a solution reading 42 on the hydrometer 
and all of them, good and bad, promptly settled to the bottom. 
They were then returned to the trough. The eggs used in this 
experiment were from a lot that had been injured during the ten- 
der stage by an operator lifting the basket by mistake when pack- 
ing for shipment. ‘They were not picked at that time and when 
the salt solution was used the good eggs in the lot were well 
eyed while the dead eggs were just at the closing of the blasto- 
pore. The good eggs were not in the least injured by the salt 
solution. 
Experiment No. 2. In this experiment the specific gravity 
scale was used and the eggs were all picked and counted befor 
placing them in the solution. In a salt solution reading 1.076 on 
the 8. G. scale 700 good eggs and 10) bad eggs were placed. 
Within three minutes 95 per cent. of the good and 5 per cent. of 
the bad eggs settled to the bottom. The bad eggs floating at the 
top were removed with the scaff net. The eggs were then re- 
turned to fresh water and well washed. After remaining in the 
fresh water for 30 minutes to remove all trace of the salt they 
were replaced in the solution, which had become diluted by the 
fresh water from the eggs and now registered 1.070 on the scale. 
In one minute all the good eggs and four of the bad ones settled 
to the bottom, while 96 bad eggs floated at the top and were re- 
moved by the net. The good eggs were all well eyed but the bad 
ones were unfertilized and had been held several weeks in pickle, 
though they were thoroughly freshened before being used. The 
good eggs were not injured by the salt solution and were packed
