Halt early enough to give time to have everything snug and in order before dark.

In selecting camping ground, look for a place where good water and wood are handy. Choose a high spot with a gentle slope if possible; guard your spring or water hole from animals, for if the day is hot your dog will run ahead of the party and jump into the middle of the spring to cool himself, and horses and cattle will befoul the water.

If camping in the Western states on the shores of a shallow stream which lies along the trail, cross the stream before making camp or you may not be able to cross it for days. A chinook wind suddenly melting the snows in the distant mountains, or a cloud-burst miles and miles up stream, may suddenly send down to you a dangerous flood even in the dry season. I have known of parties being detained for days by one of these sudden roaring floods of water, which came unannounced, the great bole of mud, sticks and logs sweeping by their camp and taking with it everything in its path.

A belt of dense timber between camp and a pond or swamp will act as a protection from mosquitoes. As a rule, keep to windward of mosquito holes; the little insects travel with the wind, not against it. 'Ware ant hills, rotten wood infested with ants, for they make poor bedfellows and are a nuisance where the food is kept.

A bare spot on the earth, where there are no dry leaves, is a wind-swept spot; where the dust-covered leaves lie in heaps the wind does not blow. A windy place is generally free from mosquitoes, but it is a poor place to build a fire; a small bank is a great protection from high wind and twisters. During one tornado I had a camp under the lee of a small elevation; we only lost the fly of one tent out of a camp of fifty or more, while in more exposed places nearby great trees were uprooted and houses unroofed.

It must not be supposed that the camping season is past because the summer vacation is over. The real camping season begins in the Wild Rice Moon, that is, September. Even if school or business takes all our time during the week, we still have week-ends in which to camp. Saturday has always been a boys' day. Camping is an American institution, because America affords the greatest camping ground in the world.

The author is seated in his own log house, built by himself, on the shores of Big Tink Pond. Back of him there is pitched a camp of six rows of tents, which are filled with a joyful, noisy crowd of youngsters.

It is here in the mountains of Pike County, Pennsylvania, where the bluestone is stratified in horizontal layers, that one may study the camp from its very birth to the latest and finished product of this century.

Everywhere in these mountains there are outcroppings of the bluestone, and wherever the face of a ridge of this stone is exposed to the elements, the rains or melting snows cause the water to drip from the earth on top of the stone and trickle down over the face of the cliff. Then, when a cold snap turns the moisture into ice in every little crack in the rock, the expansion of the ice forces the sides of the cracks apart at the seams in the rock until loose pieces from the undersides slide off, leaving small spaces over which the rock projects. The little caves thus made make retreats for white-footed mice and other small mammals, chipmunks and cave rats. When these become deeper they may become dens in which snakes sleep through the winter.

The openings never grow smaller, and in course of time are large enough for the coon, then the fox, and in olden times they made dens for wolves and panthers, or a place where the bear would "hole" up for the winter.
