I got the same leg hurt last week; I said I hadn't got hold of a spirited horse since I had been on the island, and one of the proprietors loaned me a big vicious colt; he was altogether too spirited; I went to tighten the cinch before mounting him, when he let out with his left leg (?) and kicked me across a ten-acre lot. A native rubbed and doctored me so well that I was able to stand on my feet in half an hour. It was then half after four and I had an appointment to go seven miles and get a girl and take her to a card party at five. I have been clattering around among the plantations for three weeks, now, and next week I am going to visit the extinct crater of Mount Haleakala--the largest in the world; it is ten miles to the foot of the mountain; it rises 10,000 feet above the valley; the crater is 29 miles in circumference and 1,000 feet deep. Seen from the summit, the city of St. Louis would look like a picture in the bottom of it. As soon as I get back from Haleakala (pronounced Hally-ekka-lah) I will sail for Honolulu again and thence to the Island of Hawaii (pronounced Hah-wy-ye,) to see the greatest active volcano in the world--that of Kilauea (pronounced Kee-low-way-ah)--and from thence back to San Francisco--and then, doubtless, to the States. I have been on this trip two months, and it will probably be two more before I get back to California. Yrs affy SAM. He was having a glorious time--one of the most happy, carefree adventures of his career. No form of travel or undertaking could discountenance Mark Twain at thirty. To Mrs. Orion Clemens, in Carson City: HONOLULU, May 22, 1866. MY DEAR SISTER,--I have just got back from a sea voyage--from the beautiful island of Maui, I have spent five weeks there, riding backwards and forwards among the sugar plantations--looking up the splendid scenery and visiting the lofty crater of Haleakala. It has been a perfect jubilee to me in the way of pleasure. I have not written a single line, and have not once thought of business, or care or human toil or trouble or sorrow or weariness. Few such months come in a lifetime. I set sail again, a week hence, for the island of Hawaii, to see the great active volcano of Kilauea. I shall not get back here for four or five weeks, and shall not reach San Francisco before the latter part of July. So it is no use to wait for me to go home. Go on yourselves. If I were in the east now, I could stop the publication of a piratical book which has stolen some of my sketches. It is late-good-bye, Mollie, Yr Bro SAM. To Mrs. Jane Clemens and Mrs. Moffett, in St. Louis: HONOLULU, SANDWICH ISLANDS, June 21,1866.
