The western section of the county, without being heavily timbered,is well provided in that respect, the principal growth being white andblack oak, yellow and nut pine, manzanita, and chamisal. The centralportion has a more extensive growth of pine, which has been largelyused for timbering purposes, and the original growth, which has beencut off, has been succeeded by dense forests of pines growing upon theferruginous soil, which is a proof of its strength and fertility.

In the higher mountains thereare extensive forests of white, yellow, and sugar pine, spruce, and cedar,which have afforded timber for the extensive mining operations carriedon since the gold discovery, and will afford a lasting supply for thefuture industries of the county. The timber wealth of the county has, however, had the greatestdevelopment in the Truckee Basin, which is east of the main summitof the Sierra, and bordering upon the line of the State of Nevada. Thisregion has been the scene of the most extensive lumbering operationswhich have ever been carried on in the county, there being a numberof mills of large capacity, and the product finds a market along allthe lines of the railway in the State of Nevada, Utah, and differentpoints in California, and even in Arizona and New Mexico.
