Tub IlENNEfcs Roitk.— Mr. Alonzo Piatt b8 been writing a aeries of articles, to tie Virginia City Enterprise, oo tbe advantages of tbe different mountain routes. Of tbe Hennets Pass, he says:I believe there is no mountain wagon road on the Pacific coast that has as even a grade as this; it has mainly a southern exposure, and is not subject to land or snow slides, and is built wide enough, that, with hardly an exception, loaded wagons can pass each other without difficulty. But this route and road has been up to this time a Summer road; the snow belt is wide, and the road cannot be traveled in Winter, unless freight and passenger travel can be diverted to the same from the present great j thoroughfare, the Placerville road. Last Summer and Fall stages and heavily loaded teams commenced to use said road from Sacramento,Marysville and Nevada City, and I believe it is a fact undisputed that over the road the same time can be made with heavier loads, to Nevada Territory, than over the Placerville route.! The road being the only one north of Placerville, now practicable for wagons, through, from Nevada Territory to Nevada City, Marysville and Sacramento, the completion of the railroad to Lincoln, as well as the partial completion of the Auburn and Nevada Railroad,will give to it an advantage of freighting andtravel from Sacramento, Marysville and Nevada, that will, with increased accommodation on the road, secure it a fair share of travel and freighting next Winter, and, from the situa-! tion of the country over which the road passes, i the same can be traveled in the Winter, and kept thoroughly open with less than half of the travel and freighting that pass over the Placerville route. I believe that the coining Summer will show that the California Stage Company will carry passengers from Virginia City
