You should camp out—even if you have to pitch your tent in the back yard or up on the roof! You should go to sleep on a bed of boughs,—pine, or spruce, or hickory, if possible,—or swing your hammock between the trunks of sweet-smelling forest trees, and turn your face up to the stars! You will never want to sleep in a room with closed windows after that. To see the stars looking down upon you; to see the tree-tops swaying over you; to feel the fresh night wind stealing across your face and breathing into your very soul—yes, you must sleep at least one night this summer right out on a bed of boughs; but with a blanket of wool and a piece of sail-cloth or rubber coat over you and under you, and perhaps some mosquito-netting.
