narrower, and more pointed than that of the female, while the female 

 is a little more dish-faced. 



(2) By "stripping" or squeezing the genital parts. The male fish 

 always has more or less milt in the duet leading to the genital opening, 

 and a slight pressure with the thumb and forefinger will bring some 

 milt to the surface at any season of the year. If the fish is a female 

 no effect will be produced, as the eggs will not be emitted unless ripe 

 and detached, or partly so, from the bulk of the spawn. 1 think that 

 this "stripping" will do no injury, unless it is so violent as to bruise 

 the fish. 



I have never tried to distinguish the sex of carp less than one year 

 old, and do not think that it can be done. Nor have I experimented 

 in determining the sex of other varieties of living fish. [Kemp Gaines,

(a) Salmon (Sahno solar). — Two lots of eggs, each containing 250,000, 

 were received on January 15 and January 22, 1885, in good condition, 

 from the station at Bucksport, Me. There were 2,310 dead eggs on 

 unpacking, and 5,201 died before hatching. Of the fry there was a loss 

 of 08,121 before planting. The disposition of the remaining 425,000 

 will be found in the appended table. One hundred and fifty yearling 

 salmon, from 4 to 6 inches long, were planted in Clendon Brook, Warren 

 County, New York, near Glen's Falls, where a plant of fry was also 

 made in 1881. Mr. A. N. Cheney, of Glen's Falls, writes that the fish- 

 ermen report this brook as being " alive" with young salmon ; and he has 

 promised to send specimens. 



(b) Landlocked or Schoodic salmon. — Beceived from Mr. Charles 

 G. Atkins, in charge of the station at Grand Lake Stream, Maine, 

 00,000 eggs on March 19, 1885, in excellent order; 15 dead on unpacking. 

 The total loss of eggs in hatching to April 4, 15 davs, was 142. Up to 

 April 20 the fry did well, the loss being 7,484, but with increasing temper- 

 ature the sac was absorbed rapidly, and the fish should have been planted 

 at that time. It was the intention to place them in Woodhull or Bisby 

 Lake, Herkimer County, New York, but my letters remained unan- 

 swered because of the absence of the gentleman interested in these 

 waters. We kept the fish until May 13, and the death-rate increased; 

 and I finally decided to plant them ou Long Island, after loosing over 

 38,000 fry. The table annexed will show how the fry were distributed. 



(c) Brook trout (SalrelmusfontinaJis). — We received 7,000 eggs from 

 the station at Northville, Mich., on January 31, 1885. The moss was
