To-day any one may use a pointed stick on the floor of one of these half caves and unearth, as I have done, numerous potsherds, mussel shells, bone awls, flint arrow-heads, split bones of large game animals, and the burnt wood of centuries of camp-fires which tell the tale of the first lean-to shelter used by camping man in America.
Half Caves
The projecting ledges of bluestone that have horizontal seams form half caves from the falling apart of the lower layers of the cliff caused by rain and ice and often aided by the fine roots of the black birch, rock oak, and other plants, until nature has worked long enough as a quarry-man and produced half caves large enough to shelter a stooping man (Figs. 8, 9, and 10).
Although not always necessary, it is sometimes best to make a shelter for the open face of such a cave, even if we only need it for a temporary camp (Fig. 10); this may be done by resting poles slanting against the face of the cliff and over these making a covering of balsam, pine, hemlock, palmetto, palm branches, or any available material for thatch to shed the rain and prevent it driving under the cliff to wet our bedding.
Walls
It is not always necessary to thatch the wall; a number of green boughs with leaves adhering may be rested against the cliffs and will answer for that purpose. Set the boughs upside down so that they will shed the rain and not hold it so as to drip into camp. Use your common sense and gumption, which will teach you that all the boughs should point downward and not upward as most of them naturally grow. I am careful to call your attention to this because I lately saw some men teaching Boy Scouts how to make camps and they were placing the boughs for the lads around the shelter with their branches pointing upward in such a manner that they could not shed the rain. These instructors were city men and apparently thought that the boughs were for no other purpose than to give privacy to the occupants of the shelter, forgetting that in the wilds the wilderness itself furnishes privacy.

The half cave was probably the first lean-to or shelter in this country, but overhanging cliffs are not always found where we wish to make our camp and we must resort to other forms of shelter and the use of other material in such localities.

HOW TO MAKE THE FALLEN-TREE SHELTER AND THE SCOUT-MASTER
Now that you know how to make a bed in a half cave, we will take up the most simple and primitive manufactured shelters.
Fallen-Tree Shelter
For a one-man one-night stand, select a thick-foliaged fir-tree and cut it partly through the trunk so that it will fall as shown in Fig. 11; then trim off the branches on the under-side so as to leave room to make your bed beneath the branches; next trim the branches off the top or roof of the trunk and with them thatch the roof. Do this by setting the branches with their butts up as shown in the right-hand shelter of Fig. 13, and then thatch with smaller browse as described in making the bed. This will make a cosey one-night shelter.
The Scout-Master
Or take three forked sticks (A, B, and C, Fig. 12), and interlock the forked ends so that they will stand as shown in Fig. 12. Over this framework rest branches with the butt ends up as shown in the right-hand shelter (Fig. 13), or lay a number of poles as shown in the left-hand figure (Fig. 12) and thatch this with browse as illustrated by the left-hand shelter in Fig. 13, or take elm, spruce, or birch bark and shingle as in Fig. 14. These shelters may be built for one boy or they may be made large enough for several men. They may be thatched with balsam, spruce, pine, or hemlock boughs, or with cat-tails, rushes (see Figs. 66 and 69) or any kind of long-stemmed weeds or palmetto leaves.
To Peel Bark
In the first place, I trust that the reader has enough common sense and sufficient love of the woods to prevent him from killing or marring and disfiguring trees where trees are not plenty, and this restriction includes all settled or partially settled parts of the country. But in the real forests and wilderness, miles and miles away from human habitation, there are few campers and consequently there will be fewer trees injured, and these few will not be missed.
Selecting Bark
To get the birch bark, select a tree with a smooth trunk devoid of branches and, placing skids for the trunk to fall upon (Fig. 38), fell the tree (see Figs. 112, 113, 114, 115, 116, 117, and 118), and then cut a circle around the trunk at the two ends of the log and a slit from one circle clean up to the other circle (Fig. 38); next, with a sharp stick shaped like a blunt-edged chisel, pry off the bark carefully until you take the piece off in one whole section. If it is spruce bark or any other bark you seek, hunt through the woods for a comparatively smooth trunk and proceed in the same manner as with the birch. To take it off a standing tree, cut one circle down at the butt and another as high as you can reach (Fig. 118) and slit it along a perpendicular line connecting the two cuts as in
