frame. When the eggs ai'e to be taken a small gate in the 

 front part of the box is raised, the fi-ame of the pans lowered 

 in front of the forward roller, and the crank turned. The 

 crank turns the roller, the roller, by friction, turns the endless 

 apron, and as the eggs on the apron come forward over the roller 

 they drop into the pan. When the apron has been turned one-half 

 round the eggs are all off. The pan is lifted out, the gate shut, and 

 that is all till next time. It does not require ten minutes to take the 

 largest race, and the hands are absolutely free from any contact with 

 the water. For these and other reasons, not necessary to mention 

 here, I claim that this is the best form of the Ainsworth race. The 

 great disadvantage of the whole series is that they take so much more 

 room than the race for taking artificially impregnated eggs. Into the 

 latter the fish crowd as the best place to spawn, and are daily taken 

 out, thus making room for others. In the Ainsworth they must have 

 room actually to perform the operation, and as each pair practically 

 use from twelve to twenty-five, or more, square feet, a large pond 

 must have several of these races, in order to secure all the eggs. 



I have endeavored to present a few facts relating to my subject in 

 as brief and compact a manner as possible. It will be seen that the 

 minutia?. of fish breeding are studied very closely in this country. 

 But, from the very nature of the case, it Avill still be many years 

 before the best plans are definitely settled and accepted. 



THE INTRODUCTION OF SALMON INTO AMERICAN 



WATERS. 



A paper read before tlie American Fish Culturists' Association, at its first annual 

 meeting, held at Albany, N. Y., Feb. 7th and 8tli, 1873, by Dr. M. C. Edmonds. 



The subject of the " introduction of salmon into American waters " 

 having been assigned me by the president of this Association, I shall 

 proceed, without very many preliminaries, to give you what I have 

 gleaned upon that subject. 



It is well known to you that the question of salmon culture, and 

 the introduction of salmon to our rivers is yet in its infancy, and 

 nothing sure and certain lias resulted from our labors thus far, so that 

 really the mr.tter yet remains an experiment with us. England, in 

 less than half the time, has accomplished much, goes on in the work 

 successfully, and now reaps a rich harvest from her labors. It is true 

 that we have been as faithful laborers in the field as she, and I dare 

 say should have been as successful had our efforts been as individual-
