Temporary Camps and How to Build Them For a short camping excursion, or for usewhile the permanent camp is being built, nothing is more novel and delightful thanthe temporary camp built of the materialsever ready in the woods.. The Indian Camp The simplest form of all perhaps is theIndian camp. To build this, cut an ever-green tree nearly through about five feetabove the base of the trunk, so that whenthe top falls the butt will still be attachedto the stump. Hollow out the under sideof the treetop by removing boughs andbranches. Use the trunk of the fallen partas a ridge pole and bank boughs andbranches from it to the ground on eitherside. The shelter thus formed will be verycomfortable, but there are other kinds bet-ter calculated to protect from heavy rain-storms. A wigwam sheds rain well becauseits sides are so steep.
