If the guard sights a fire anywhere within the watershed of Lake Tahoe, he immediately obtains men at the nearest point and proceeds to the fire. Since the launch has been on the Lake there have been no serious fires. Every fire has been caught in its infancy and put out before any damage has been done. There has been only one fire of any size on the Lake since the launch was installed. This burned about 20 acres just east of Brockway. Numerous small fires of an acre or less have been put out each year.
The Forest Guard in charge of the launch for the years 1912-13 was Mark W. Edmonds. Mr. Edmonds is the son of Dr. H.W. Edmonds, who is now in the Arctic doing scientific work for the Carnegie Institute.
The force of men at work on the Reserve varies in number according to the season of the year. When the fire-season is on many more men are on duty than in the winter-season. The year-long force consists of the Supervisor, Deputy Supervisor, Forest Clerk, Stenographer, thirteen Rangers and two Forest Examiners who are Forest School men engaged chiefly on timber sale and investigative work. The force in 1913 during the season of greatest danger was fifty-six. Some of the temporary employees are engaged for six months, some for three months and others for shorter periods. The longer termed men are generally Assistant Rangers who cannot be employed the year around, but who are considered first for permanent jobs that occur on the statutory roll on account of their Civil Service standing.
Forest fires are caused in a variety of ways, but chiefly through inexcusable carelessness. Now and then lightning produces fire, but the throwing down of lighted matches by smokers, the butt ends of cigars and cigarettes that are still alight, leaving camp-fires unextinguished, or building them too large, allowing fires for burning waste land or brush to get from under control—these are the chief sources of forest fires. Accordingly the local and federal authorities constantly keep posted on Forest Reserves notices calling attention to the dangers and urging care upon all who use the forests for any purpose whatever.
In addition to fire-fighting the rangers are required to give constant oversight to the sheep- and cattle-ranges, and to the animals that are brought there, so that the feed is not eaten out, or too many head pastured upon a given area. Seeds of forest trees must be gathered at the proper season and experiments in reforestation conducted, besides a certain amount of actual planting-out performed. The habits of seed-eating birds and animals are studied, especially in relation to reforestation. A very small number of squirrels or mice can get away with a vast number of seeds in a season. Methods of protecting the seeds without destroying too many of the wild animals must be devised.
Available areas of timber are sought for and offered for sale. Certain men are detailed to measure the trees and determine the value of the timber; they must mark the trees included in the sale, leaving out enough seed-trees for satisfactory reproduction. If it be a second sale over a cut-over area the problems are somewhat altered. Will the trees that are left suffer from wind-fall? If partially suppressed trees are left can they be depended upon to recover and make a good growth?
Then, too, the questions of natural versus artificial reforestation have to be scientifically studied and exhaustive tests made. Shall seeds be sown, or shall young trees be planted? Which trees are best suited for certain localities, and which are the more profitable when grown?
To many people it is not known that dwellers in or near National Forests can obtain free of charge timber for their domestic needs. The rangers determine where this "free area" shall be located, exactly what trees, whether dead or alive, shall be taken, and endeavor to lay down rules that shall give equal chances for all comers.
As one of the mottos of the Forest Service is "the greatest good to the greatest number," small sales are encouraged to those who wish to make their own lumber or shakes. Settlers in remote localities are often helped in this manner.
Cases of trespass have to be guarded against, and now and again suits have had to be brought against loggers for encroaching upon the territory of the Reserve, and removing timber which they had not purchased.
