Aside from those due to lightning, most forest fires are now either set purposely or come from engine sparks or from somebody's carelessness. Many fires are set purposely by stockmen who think by this means to clear away the brush and thus obtain better feed for their cattle and sheep. These men often care nothing for the forests or for the preservation of the summer water flow. They would, indeed, be pleased to see all the forests burned away if by that means they could increase their feed. If you could travel through some of the mountainous portions of the Southwest, you would see how much harm has been done in this way to the trees, the streams, and the soil.
It is a hot summer day and two men are riding along a mountain road. One of them thoughtlessly throws away a lighted cigarette, which falls upon some dry pine needles. In a few moments the pine needles are ablaze. The fire spreads with incredible rapidity and a great column of smoke rises above the treetops. Before any one can reach it, the fire is sweeping up the mountain side, and it may not be stopped before it has destroyed thousands of acres of valuable timber. All this terrible loss is due to one careless man who, in the first place, should not have been smoking cigarettes, and in the second place should have known better than to throw a spark into the forest powder magazine.
Some campers, enjoying the summer in the mountains, go away leaving their fire burning. By and by a stick burns outward until the fire reaches the leaves, or a gust of wind comes along and carries a spark to them. In the hot sun the leaves and needles are almost as easy to ignite as powder, and in a few moments another fire is making headway into the surrounding forest.
A farmer clearing land thinks he can get rid of the brush and young trees more easily by burning. But the undergrowth is drier than he thought, and, the wind coming up unexpectedly, the fire is soon beyond his control. It may destroy his own fences and buildings and, sweeping on, ruin those of his neighbors also.
H. W. Fairbanks
The dead stubs of a once beautiful forest.
Few people have perished from fires in the West, for there the forest regions are generally thinly inhabited, but in some of the Eastern and Northern states there have been terrible fires that have destroyed whole villages together with their inhabitants.
In many mountain regions of our country there are large areas now covered with useless brush where there were once valuable forests. In regions where the lumbermen have not utterly destroyed the forests, but have left some seed trees, the forests will come back again, but in these large burned areas conditions are not favorable. The destruction of the humus as well as the trees has been so complete that the seeding of a new forest is slow work. It may be hundreds of years before the trees will spread over and again take possession of the waste land.
A single fire often destroys more timber than would be destroyed by a whole camp of loggers working for years. In the Northwest there are many sad and desolate pictures of the destruction caused by forest fires. We may travel for miles through forests of tall, dead stubs, the remains of once noble trees. Where they have fallen the trunks lie piled many feet high and trails had to be cut through an almost solid mass of timber.
