reticulations, relieved with irregular, yellowish spots not placed in rows. 
Our fishermen say that the Muskallonge is spotted with black, and the 
Pike with yellow.” 
Habiis.—The Muskallonge is much less common than the Pike, and is 
found almost exclusively in the deep waters of the lakes, “except for a 
few days in spring, when it runs into the mouths of rivers to spawn.” 
It reaches an immense size. Dr. Kirtland mentions one more than five 
feet in length, and weighing over sixty pounds. The largest one of 
which I have a record was six feet long and weighed eighty pounds. It 
is highly valued for food. Dr. Kirtland informs us that “epicures con- 
sider it one of the best of fishes of the West,’ and Mr. J. L. Beaman af- 
firms that ‘‘as a food fish there is nothing superior to this. He ranks 
with the Salmon and Speckled Trout, and surpasses the Black and 
Striped Bass. The meat is almost as white as snow, fine-grained, nicely 
laminated, and the flavor is perfect.” 
The Muskallunge is as voracious as the Pike, and eighty pounds of Mus- 
kallunge represents several tons of Minnows, White-fish, and the like. 
It is not a common fish. Its great size and voracity perhaps account for 
this. ‘It is a long, slim, strong, and swift fish, in every way formed for 
the life it leads, that of a fierce and dauntless marauder.” (Hallock.)
