MY DEAR MOTHER AND SISTER,--I have just got back from a hard trip through the Island of Hawaii, begun on the 26th of May and finished on the 18th of June--only six or seven days at sea--all the balance horse-back, and the hardest mountain road in the world. I staid at the volcano about a week and witnessed the greatest eruption that has occurred for years. I lived well there. They charge $4 a day for board, and a dollar or two extra for guides and horses. I had a pretty good time. They didn't charge me anything. I have got back sick--went to bed as soon as I arrived here--shall not be strong again for several days yet. I rushed too fast. I ought to have taken five or six weeks on that trip. A week hence I start for the Island of Kauai, to be gone three weeks and then I go back to California. The Crown Princess is dead and thousands of natives cry and wail and dance and dance for the dead, around the King's Palace all night and every night. They will keep it up for a month and then she will be buried. Hon. Anson Burlingame, U. S. Minister to China, and Gen. Van Valkenburgh, Minister to Japan, with their families and suites, have just arrived here en route. They were going to do me the honor to call on me this morning, and that accounts for my being out of bed now. You know what condition my room is always in when you are not around--so I climbed out of bed and dressed and shaved pretty quick and went up to the residence of the American Minister and called on them. Mr. Burlingame told me a good deal about Hon. Jere Clemens and that Virginia Clemens who was wounded in a duel. He was in Congress years with both of them. Mr. B. sent for his son, to introduce him--said he could tell that frog story of mine as well as anybody. I told him I was glad to hear it for I never tried to tell it myself without making a botch of it. At his request I have loaned Mr. Burlingame pretty much everything I ever wrote. I guess he will be an almighty wise man by the time he wades through that lot. If the New United States Minister to the Sandwich Islands (Hon. Edwin McCook,) were only here now, so that I could get his views on this new condition of Sandwich Island politics, I would sail for California at once. But he will not arrive for two weeks yet and so I am going to spend that interval on the island of Kauai. I stopped three days with Hon. Mr. Cony, Deputy Marshal of the Kingdom, at Hilo, Hawaii, last week and by a funny circumstance he knew everybody that I ever knew in Hannibal and Palmyra. We used to sit up all night talking and then sleep all day. He lives like a Prince. Confound that Island! I had a streak of fat and a streak of lean all over it--got lost several times and had to sleep in huts with the natives and live like a dog. Of course I couldn't speak fifty words of the language. Take it altogether, though, it was a mighty hard trip.
