of the hatching one of the distinguishing marks is : In the 

 unimpregnated egg a small annular disc, with a smaller 

 round dot in the centre, will be seen on the top of the egg, 

 and will remain there until the egg turns white, while that 

 on the sound egg will disappear in twenty-four hours. The 

 first appearance of the alevins (q.v.) or hatched fishes is like 

 little splinters of dark wood about half an inch long ; the 

 yolk of the egg is attached to them, and remains so until it is 

 absorbed, and the alevins begin to feed, and are now called 

 fry. In six or seven days the alevins begin to move about 

 in an aimless fashion, and need no attention except to keep 

 screens clean and the water flowing nicely. About the 

 twenty-fifth day the egg sac is quite absorbed, and then the 

 trout fry must be fed first with hard-boiled yolk of eggs 

 beaten up very fine, and afterwards with liver and curd. 

 They must be fed four times a day until they are one year 

 old. It has been found that occasionally throwing some 

 loamy soil into the water has a great tendency to prevent 

 many of the diseases to which young fry are liable. The 

 yearlings can be put into ponds or streams, or may be 

 transported to stronger water with perfect safety. The 

 average length of well-cared for healthy fry at a year 

 old is about three inches. The following description of 

 salmon hatching has been kindly furnished to me by Messrs. 

 Foley, of Lismore, Co. Waterford, Ireland, who have been 

 very successful in their extensive hatching establishment, 

 which has been arranged on the latest and most improved 

 principles. As they are the lessees of the Blackwater 

 fishery it is almost a necessity for them to breed and 

 increase salmon largely, seeing that they are under a heavy 

 rent: "Some years ago an attempt was made to propagate 

 salmon artificially, but such was the difficulty of obtaining
