A California correspondent says: " There is a very sensible article in the Nation of the 1st inst., on the " Present and future of the Sierra Forests," by Prof. C. S. Sargent, Director of the Botanic Garden of Harvard University, that will well repay perusal. The fire fiend, and sheep nuisance are rapidly denuding our grand old forests of the Sierra; burning up the grown trees, and eating up the young. Where once stood a luxurious forest growth there is now a fire and sheep created desert. From a single stand-point (the south dome of Yosemite), I counted at one time, nineteen large fires, with their tongues of flame licking up the young trees the sheep had spared, and sweeping off whole forests of grown trees set on fire by sheepmen. Who does not execrate this ?"
