Here we are again, and here is your letter of Sept. 24th. I got down last evening, and boo! was I not weary after pushing through the rough upper half of the great Tuolumne Cañon? I have climbed more than twenty-four thousand feet in these ten days, three times to the top of the glacieret of Mt. Hoffman, and once to Mts. Lyell and McClure. I have bagged a quantity of Tuolumne rocks sufficient to build a dozen Yosemites; stripes of cascades longer than ever, lacy or smooth and white as pressed snow; a glacier basin with ten glassy lakes set all near together like eggs in a nest; then El Capitan and a couple of Tissiacks, cañons glorious with yellows and reds of mountain maple and aspen and honeysuckle and ash and new indescribable music immeasurable from strange waters and winds, and glaciers, too, flowing and grinding, alive as any on earth. Shall I pull you out some? Here is a clean, white-skinned glacier from the back of McClure with glassy emerald flesh and singing crystal blood all bright and pure as a sky, yet handling mud and stone like a navvy, building moraines like a plodding Irishman. Here is a cascade two hundred feet wide, half a mile long, glancing this way and that, filled with bounce and dance and joyous hurrah, yet earnest as tempest, and singing like angels loose on a frolic from heaven; and here are more cascades and more, broad and flat like clouds and fringed like flowing hair, with occasional falls erect as pines, and lakes like glowing eyes; and here are visions and dreams, and a splendid set of ghosts, too many for ink and narrow paper. I have not heard anything concerning Le Conte’s glacier lecture, but he seems to have drawn all he knows of Sierra glaciers and new theories concerning them so directly from here that I cannot think that he will claim discovery, etc. If he does, I will not be made poorer. Professor Kneeland, Secretary Boston Institute of Technology, gathered some letters I sent to Runkle and that “Tribune” letter, and hashed them into a compost called a paper for the Boston Historical Society, and gave me credit for all of the smaller sayings and doings and stole the broadest truth to himself. I have the proof-sheets of “The Paper” and will show them to you some time. But all of such meanness can work no permanent evil to any one except the dealer. As for the living “glaciers of the Sierras,” here is what I have learned concerning them. You will have the first chance to steal, for I have just concluded my experiments on them for the season and have not yet cast them at any of the great professors, or presidents.
