Note 4 — SECOND DAY. HALIEUS—POIETES—ORNITHER—PHYSICUS. TROUT FISHING, DENHAM.—MAY, 1810.

I have known the number of spines in the pectoral fins different, in different varieties of trout; I have seen them 12, 13, and 14: but the anal fin always, I believe, contains 11 spines, the dorsal 12 or 13, the ventral 9, and the caudal 21. The smallest brook trout, when well and copiously fed, will increase in stews to four or five pounds in weight, but never attains the size or characters of lake trout.

Mr. Tonkin of Polgaron put some small river trout, 2½ inches in length, into a newly-made pond. He took some of these out the second year, and they were above 12 inches in length; the third year, he took one out that was 16 inches; and the fourth year, one of 25 inches: this was in 1734.
