We have been here since June 21st. For a little while we had some warm days--according to the family's estimate; I was hardly discommoded myself. Otherwise the weather has been of the sort you are familiar with in these regions: cool days and cool nights. We have heard of the hot wave every Wednesday, per the weekly paper--we allow no dailies to intrude. Last week through visitors also--the only ones we have had--Dr. Root and John Howells. We have the daily lake-swim; and all the tribe, servants included (but not I) do a good deal of boating; sometimes with the guide, sometimes without him--Jean and Clara are competent with the oars. If we live another year, I hope we shall spend its summer in this house. We have taken the Appleton country seat, overlooking the Hudson, at Riverdale, 25 minutes from the Grand Central Station, for a year, beginning Oct. 1, with option for another year. We are obliged to be close to New York for a year or two. Aug. 3rd. I go yachting a fortnight up north in a 20-knot boat 225 feet long, with the owner, (Mr. Rogers), Tom Reid, Dr. Rice, Col. A. G. Paine and one or two others. Judge Howland would go, but can't get away from engagements; Professor Sloane would go, but is in the grip of an illness. Come--will you go? If you can manage it, drop a post-card to me c/o H.H. Rogers, 26 Broadway. I shall be in New York a couple of days before we sail--July 31 or Aug. 1, perhaps the latter,--and I think I shall stop at the Hotel Grosvenor, cor. 10th St and 5th ave. We all send you and the Harmonies lots and gobs of love. MARK ***** To Rev. J. H. Twichell, in Hartford: AMPERSAND, N. Y., Aug. 28. DEAR JOE,--Just a word, to scoff at you, with your extravagant suggestion that I read the biography of Phillips Brooks--the very dullest book that has been printed for a century. Joe, ten pages of Mrs. Cheney's masterly biography of her fathers--no, five pages of it--contain more meat, more sense, more literature, more brilliancy, than that whole basketful of drowsy rubbish put together. Why, in that dead atmosphere even Brooks himself is dull--he wearied me; oh how he wearied me! We had a noble good time in the Yacht, and caught a Chinese missionary and drowned him. Love from us all to you all. MARK. The assassination of President McKinley occurred September 6, 1901. Such an event would naturally stir Mark Twain to comment on human nature in general. His letter to Twichell is as individual as it is sound in philosophy. At what period of his own life, or under what circumstances, he made the long journey with tragic intent there is no means of knowing now. There is no other mention of it elsewhere in the records that survive him. ***** To Rev. J. H. Twichell, in Hartford:
