Smudges
Smudges are said to afford relief in camp, but my own experience has been that the insects can stand them better than I. A smudge is made by burning things that make little flame and much smoke. Dead leaves, not too dry, will make a fairly good smudge, but a better way is to burn damp cedar bark, or branches, on piles of hot coals taken from the camp-fire and kept alive at different sides of the camp.
The accounts of extreme suffering caused by insect bites come from unusually sensitive people. All people are not affected alike. Two persons from one camp will tell entirely different stories of their experience with insects. The best way to encounter these, as all other annoyances, is to protect yourself as well as you can and then, without whimpering, make the best of the situation. All the pests described will not fall upon you at once, and, taken singly or even doubly, you will manage to survive the ordeal. If the pleasure of the trail did not over-balance the pain there would be fewer campers to relate their troubles.
