I took him up to the farmhouse and started him slowly on some deviled trout and watercress. Poor fellow, he reminded me of a young setter dog born and brought up in the city and taken afield for the first time. Well, that young man did nothing but cry and eat for two weeks. He then went home to tell his folks he had come to life, and then hurried out to feed and weep for another month. I know a hundred young men and women in New York who are in a bad way with the city complaint. The streets are filled with ghost-like creatures. Lord Derby is right: "If you do not find time for exercise you will have to find time for illness."

"To-morrow we will go a-fishing; do thou go now and fetch the bait."—Hymir to Thar.


CHAPTER XVIII

THE BROOK TROUT

"Then, give me the trout of the mountain stream.
With his crimson stars and his golden gleam;
When he, like a hero, on the moss lies.
The Angler has won his fairest prize!"
Author Unknown.

Trout Taking Flies.—"Trout invariably strike the insect first with their tails, knocking it into the water and then devouring it with a swift dart which can hardly be distinguished from the original movement, so quickly does one succeed the other."—W. C. Prime.

Trout Colors.—The color of a trout's back depends on the color of the bottom of the river. Rapidly growing trout differ greatly in spots and color from those which grow slowly and thrive badly. A middle-aged trout differs in color from an aged trout. Speaking generally, the young, healthy, fast-growing fish will have silvery sides, white belly, and plenty of well-defined spots. The poorly fed fish will have few or no spots, a drab belly, and muddy yellow sides. Old trout are particularly lank and large-headed.
