PROGRESS AND EXPERIMENTS IN FISH CULTURE 
DURING THE PAST YEAR IN THE 
BUREAU OF FISHERIES. 
BY JOHN W. TITCOMB, ASSISTANT IN CHARGE OF DIVISION OF FISH 
CULTURE. 
Perhaps the most interesting and important discovery is 
that of Superintendent Henry O’Malley of the Baker Lake sta- 
tion on the Use of the Salt Solution as an Aid to Fish Culture. 
His paper on this subject, given elsewhere, is self explanatory. 
Tests made at other salmon stations prove the value of the 
discovery when it becomes desirable to remove a large number 
of dead eggs after they have passed the more tender stages of 
development. For instance, all unfertilized eggs can be re- 
moved when preparing a lot for transportation in egg cases. The 
experiments of Superintendent Lambson as reported by him are 
here given: 
First. Eggs of 486 temperature units development with an 
equal number of dead eggs were placed in a salt solution of one 
part salt to six parts water. Eggs showed no signs of injury 
the day following. 
Second. Equal numbers of good and bad eggs were placed in 
a solution of one of salt and seven of water. All eggs remained 
suspended just below the surface, and no separation between the 
good and bad occurred. No injury to good eggs followed the 
immersion. 
Third. Equal numbers of good and bad eggs were placed in 
a solution of one of salt to eight of water. After three minutes 
good eggs began to settle to the bottom, after five and a half 
minutes all good eggs had settled leaving none but dead eggs 
floating, these were readily poured off. 
Fourth. Equal numbers of good and bad eggs were placed in 
a solution of one of salt to nine of water. At the end of fifteen 
seconds the good eggs began to settle; in two minutes none but 
good eggs remained at the surface, this gave best results. 
Fifth. Equal numbers of good and bad eggs were placed in a
