struggle by a knife-thrust straight into the heart.
To many this may seem a cruel sport, and in a certain sense it assuredly is; but my young readers must remember that cougars and other wild beasts are a menace to civilization in the far West, and they have been shot down and killed at every available opportunity.

He is a naturalist, and examines with care everything brought down and reports upon it, so that his hunting trips have added not a little to up-to-date natural history. The skulls of the various animals killed on this trip were forwarded to the Biological Survey, Department of Agriculture, Washington, and in return Mr. Roosevelt received a letter, part of which stated:—
"Your series of skulls from Colorado is incomparably the largest, most complete, and most valuable series ever brought together from any single locality, and will be of inestimable value in determining the amount of individual variation."
