NATURALIZATION OF FISHES. 187 



smaller lakes. They are known in Canada as " Lunge," 

 in some of the Eastern States as " Togue," the average 

 of the species in the smaller lakes not exceeding three or 

 four pounds. Experiments were made last winter by Mr. 

 Robinson, of Meredith, N. H., in hatching the ova of the 

 lake trout found in his vicinity. In a letter to Mr. Ains- 

 worth he says : "In regard to our lake trout, I am making 

 the experiment of hatching them, under the patronage 

 of the New Hampshire Commissioners. I am well satis- 

 fied with the result thus far, considering my want of know- 

 ledge in the business. I think that, with a little more 

 light on the subject, I can make a perfect success. I lost 

 a great many spawn by bringing them home in buckets, 

 sitting in the bottom of a wagon, and others by being 

 jarred in a boat beating to windward in a heavy sea. All 

 I transported without jar are hatching well. There is no 

 real trouble in obtaining the spawn. The fish come on the 

 shoals to spawn, and can be taken in mesh-nets without at 

 all injuring the fish. I captured some 250 fish of both 

 sexes, and after manipulating, returned them to the lake 

 , and killed but few. Those I took were of the proportion 

 of five or six males to one female. The amount of spawn 

 I should judge would be about the same as salmon, say 

 about 2000 for a two-pound fish and upwards, to 10,000 

 for a ten-pounder." 



There is but little doubt that any of the species referred to 

 can be naturalized in lakelets that are suitable to the black 

 bass of the northern lakes.' They do not appear to be pro- 

 lific, as they are not found in great numbers in the lakes
