Centennial Meeting. 41 



coloring pattern is a series of oval, white or chocolate spots on 

 a greenish ground. The muskellunge, Esox nobilior, has the 

 lower portion of cheek and operculum and the sub-operculum 

 naked, and has oval, black spots on a dusky, greenish ground. 

 These characters are strongly marked, and a slight examination 

 suffices to determine the species. 



Mr. Mather then gave some interesting remarks on the 

 grayling. He regarded the grayling as certainly being much 

 easier to propagate than the trout, but he did not think it as 

 good a food-fish. He held that when it came to a question of 

 the table, no fresh-water fish was equal, as an edible, to fish of 

 the salt-water varieties. The grayling is a gamey, handsome 

 fish, and makes his home in the same kind of streams in which 

 the trout is to be found. It affords much sport to the angler, 

 and in certain portions of the trout-fishing country is one of 

 the delights of trout-fishing, giving him the same delightful 

 surroundings that have made that sport so popular. He could 

 not tell what was the lowest temperature at which the grayling 

 would thrive, but it lived and did well in his ponds at Honevone 

 Falls, and also at Caledonia, N. Y. Those which he brought 

 from Michigan three years ago were within two weeks of their 

 spawning-time when brought from there, but they had never 

 spawned yet. The only eggs which he had procured and 

 hatched had been taken from the fish in their native waters. He 

 will hatch them in the New York Aquariam during the coming 

 winter or next spring. 



Col. James Worrall of Pennsylvania, a member of the Fish 

 Commission of that State, made a further statement of the 

 results of his observations and practical experience upon these 

 improvements in fish-ways, particularly as to the one at Co- 

 lumbia, Penn. The salmon family, he stated, had for years gone
