A Book-Lover's Holidays in the Open is a classic nature text by Teddy Roosevelt. The man should have youth and strength who seeks outdoor adventure in the wide, waste spaces of the earth, in the marshes, and among the vast mountain masses, in the northern forests, amid the steaming jungles of the tropics, or on the deserts of sand or of snow. He must long greatly for the lonely winds that blow across the wilderness, and for sunrise and sunset over the rim of the empty world.
