SIXTEENJH ANNUAL MEETING. 13 



(^>L. McDonald. — So far, I have found no satisfaction in hand- 

 ling o-lutinous eggs, and the only real success I have met with 

 was with the eggs of the white perch. We had collected some 

 adult tisii for Mr. Mather to send to Germany, and they were 

 put in a perforated can in the river to keep for a few days, and 

 on taking it out we found the side of the can coated with eggs, 

 and sent it to the central station, hardly expecting any results, 

 as we were not certain that the eggs vveie impregnated. In three 

 ur four days a large proportion of the eggs hatched; we had 

 given tiiem no attention at all, but simply left them alone. The 

 eggs were evenly distributed on the can, and not hung in masses; 

 now, perhaps as good a thing to do with glutinous eggs is to let 

 them alone. The eggs of the yellow perch are laid in rov^^s and 

 hung over twigs and are merely suspended, where the eggs hatch 

 without being disturbed. The catfish also lays glutinous eggs, 

 but they are not stuck together; when the female lays them she 

 leaves the male to hover over them. Now% it may be, that in all 

 our attempts to hatch glutinous eggs we have only tried the 

 same methods which jve used in handling eggs which are non- 

 adhesive, and have departed too far from nature in this matter. 



Mr. Mather. — You will notice in my report I mention the 

 fact that all the wdiite perch which we tried to keep and feed 

 died. 



CoL. McDonald. — So did ours, and I would like to hear from 

 Mr. Marks about the "jack-salmon," or pike-perch, and what 

 success he has had in hatching the glutinous eggs of this fish. 



Mr. Marks. — We have hatched them for the past two years, 

 and always by separating the eggs, and never in any other way. 

 Although it is a long and tedious process to break the adhesive 

 character of the eggs, it is the only way we have ever succeeded. 

 Mr. Nevin has a paper on the hatching of the fish, and I can only 

 say that our method is the same as his. The eggs are taken in 

 the rivers and transported to the hatcher)- on trays. 



The Scjciety then adjourned until 2 p. m. 



At the opening of the afternoon session, the Secretary read 

 the foil (J wing paper:
