sorbing or
difficult piece of literature, that his mind seemed to fold up and shut
most of the world away. Soon after his return from Europe, when he was
still struggling with 'A Tramp Abroad', he wearily put the manuscript
aside, one day, and set out to invite F. G. Whitmore over for a game of
billiards. Whitmore lived only a little way down the street, and Clemens
had been there time and again. It was such a brief distance that he
started out in his slippers and with no hat. But when he reached the
corner where the house, a stone's-throw away, was in plain view he
stopped. He did not recognize it. It was unchanged, but its outlines
had left no impress upon his mind. He stood there uncertainly a little
while, then returned and got the coachman, Patrick McAleer, to show him
the way.

The second, and still more picturesque instance, belongs also to this
period. One day, when he was playing billiards with Whitmore, George,
the butler, came up with a card.

"Who is he, George?" Clemens asked, without looking at the card.

"I don't know, suh, but he's a gentleman, Mr. Clemens."

"Now, George, how many times have I told you I don't want to see
strangers when I'm playing billiards! This is just some book agent, or

him, and I'm not going to."

"Oh, but this is a gentleman, I'm sure, Mr. Clemens. Just look at his
card, suh."

"Yes, of course, I see--nice engraved card--but I don't know him, and if
it was St. Peter himself I wouldn't buy the key of salvation! You tell
him so--tell him--oh, well, I suppose I've got to go and get rid of him
myself. I'll be back in a minute, Whitmore."

He ran down the stairs, and as he got near the parlor door, which stood
open, he saw a man sitting on a couch with what seemed to be some framed
water-color pictures on the floor near his feet.

"Ah, ha!" he thought, "I see. A picture agent. I'll soon get rid of
him."

He went in with his best, "Well, what can I do for you?" air, which he,
as well as any man living, knew how to assume; a friendly air enough, but
not encouraging. The gentleman rose and extended his hand.

"How are you, Mr. Clemens?" he said.

Of course this was the usual thing with men who had axes to grind or
goods to sell. Clemens did not extend a very cordial hand. He merely
raised a loose, indifferent hand--a discouraging hand.

"And how is Mrs. Clemens?" asked the uninvited guest.

So this wa
