Among the many pleasant neighbors at Riverdale were the Dodges, the Quincy Adamses, and the Rev. Mr. Carstensen, a liberal-minded minister with whom Clemens easily affiliated.  Clemens and Carstensen visited back and forth and exchanged views.  Once Mr. Carstensen told him that he was going to town to dine with a party which included the Reverend Gottheil, a Catholic bishop, an Indian Buddhist, and a Chinese scholar of the Confucian faith, after which they were all going to a Yiddish theater.  Clemens said: 

“Well, there’s only one more thing you need to make the party complete —­that is, either Satan or me.”

Howells often came to Riverdale.  He was living in a New York apartment, and it was handy and made an easy and pleasant outing for him.  He says: 

“I began to see them again on something like the sweet old terms.  They lived far more unpretentiously than they used, and I think with a notion of economy, which they had never very successfully practised.  I recall that at the end of a certain year in Hartford, when they had been saving and paying cash for everything, Clemens wrote, reminding me of their avowed experiment, and asking me to guess how many bills they had at New-Year’s; he hastened to say that a horse-car would not have held them.  At Riverdale they kept no carriage, and there was a snowy night when I drove up to their handsome old mansion in the station carryall, which was crusted with mud, as from the going down of the Deluge after transporting Noah and his family from the Ark to whatever point they decided to settle provisionally.  But the good talk, the rich talk, the talk that could never suffer poverty of mind or soul was there, and we jubilantly found ourselves again in our middle youth.”

Both Howells and Clemens were made doctors of letters by Yale that year and went over in October to receive their degrees.  It was Mark Twain’s second Yale degree, and it was the highest rank that an American institution of learning could confer.

Twichell wrote: 

I want you to understand, old fellow, that it will be in its intention the highest public compliment, and emphatically so in your case, for it will be tendered you by a corporation of gentlemen, the majority of whom do not at all agree with the views on important questions which you have lately promulgated in speech and in writing, and with which you are identified to the public mind.  They grant, of course, your right to hold and express those views, though for themselves they don’t like ’em; but in awarding you the proposed laurel they will make no count of that whatever.  Their action will appropriately signify simply and solely their estimate of your merit and rank as a man of letters, and so, as I say, the compliment of it will be of the pure, unadulterated quality.

Howells was not especially eager to go, and tried to conspire with Clemens to arrange some excuse which would keep them at home.
