Their destination was Edinburgh, where they remained a month. Mrs. Clemens's health gave way on their arrival there, and her husband, knowing the name of no other physician in the place, looked up Dr. John Brown, author of Rab and His Friends, and found in him not only a skilful practitioner, but a lovable companion, to whom they all became deeply attached. Little Susy, now seventeen months old, became his special favorite. He named her Megalops, because of her great eyes. Mrs. Clemens regained her strength and they returned to London. Clemens, still urged to lecture, finally agreed with George Dolby to a week's engagement, and added a promise that after taking his wife and daughter back to America he would return immediately for a more extended course. Dolby announced him to appear at the Queen's Concert Rooms, Hanover Square, for the week of October 13-18, his lecture to be the old Sandwich Islands talk that seven years before had brought him his first success. The great hall, the largest in London, was thronged at each appearance, and the papers declared that Mark Twain had no more than “whetted the public appetite” for his humor. Three days later, October 1873, Clemens, with his little party, sailed for home. Half-way across the ocean he wrote the friend they had left in Scotland: ***** To Dr. John Brown, in Edinburgh: MID-ATLANTIC, Oct. 30, 1873. OUR DEAR FRIEND THE DOCTOR,--We have plowed a long way over the sea, and there's twenty-two hundred miles of restless water between us, now, besides the railway stretch. And yet you are so present with us, so close to us that a span and a whisper would bridge the distance. The first three days were stormy, and wife, child, maid, and Miss Spaulding were all sea-sick 25 hours out of the 24, and I was sorry I ever started. However, it has been smooth, and balmy, and sunny and altogether lovely for a day or two now, and at night there is a broad luminous highway stretching over the sea to the moon, over which the spirits of the sea are traveling up and down all through the secret night and having a genuine good time, I make no doubt. Today they discovered a “collie” on board! I find (as per advertisement which I sent you) that they won't carry dogs in these ships at any price. This one has been concealed up to this time. Now his owner has to pay L10 or heave him overboard. Fortunately the doggie is a performing doggie and the money will be paid. So after all it was just as well you didn't intrust your collie to us. A poor little child died at midnight and was buried at dawn this morning--sheeted and shotted, and sunk in the middle of the lonely ocean in water three thousand fathoms deep. Pity the poor mother. With our love. S. L. CLEMENS.
