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.
