These earthquakes have made me immensely rich. I had long been aware of the life and gentle tenderness of the rocks, and, instead of walking upon them as unfeeling surfaces, began to regard them as a transparent sky. Now they have spoken with audible voice and pulsed with common motion. This very instant, just as my pen reached “and” on the third line above, my cabin creaked with a sharp shock and the oil waved in my lamp. We had several shocks last night. I would like to go somewhere on the west South American coast to study earthquakes. I think I could invent some experimental apparatus whereby their complicated phenomena could be separated and read, but I have some years of ice on hand. ’Tis most ennobling to find and feel that we are constructed with reference to these noble storms, so as to draw unspeakable enjoyment from them. Are we not rich when our six-foot column of substance sponges up heaven above and earth beneath into its pores? Aye, we have chambers in us the right shape for earthquakes. Churches and the schools lisp limpingly, painfully, of man’s capabilities, possibilities, and fussy developing nostrums of duties, but if the human flock, together with their Rev.’s and double L-D shepherds, would go wild themselves, they would discover without Euclid that the solid contents of a human soul is the whole world. Our streams are fast obtaining their highest power; warm nights and days are making the high mountain snow into snow avalanches and snow-falls; violets, blue, white, and yellow, abound; butterflies [flit] through the meadows; and mirror shadows reveal new heavens and new earths everywhere. Remember me to the Doctor and all the boys and to McChesney and the brotherhood. Cordially, J. MUIR. Independence, October 16th, 1873. All of my season’s mountain work is done. I have just come down from Mt. Whitney and the newly discovered mountain five miles northwest of Whitney, and now our journey is a simple saunter along the base of the range to Tahoe, where we will arrive about the end of the month or a few days earlier. I have seen a good deal more of the high mountain region about the head of Kings and Kern rivers than I expected to do in so short and so late a time.
