So, as I have said, the organ was contracted for, was built, and an additional series of trials began.  Upon a very important occasion the organ declined to shriek, although every effort to persuade it to perform the functions for which it was designed was made.  Forty or fifty very charming people were gathered together to be introduced to the virtues of the new instrument—­for Carson was not the kind of man to keep to himself the good things which came into his life; he shared all his blessings, while keeping his woes to himself; a well-known virtuoso was retained to set forth the possibilities of the acquisition, and all was going as “merry as a marriage bell” when suddenly there came a wheeze, and the fingers of the well-known virtuoso were powerless to elicit the harmonious shrieks which all had come to hear.

It was a sad moment, but Carson was equal to the occasion.

“Something’s out of gear,” he said, with a laugh due rather to his philosophical nature than to mirth.  “I’m afraid we’ll have to finish on the piano.”

And so we did, and a delightful evening we had of it, although many of us went home wondering what on earth was the matter with the organ.

A few days later I met Carson on the train and the mystery was solved.

“The trouble was with the water-pipes,” he explained.  “They were put in wrong, and the location of the house is such that every time Colonel Hawkins, on the other side of the street, takes a bath, all the water that flows down the hill is diverted into his tub.”

I tried not to laugh.

“You’ll have to enter into an agreement with the Colonel,” I said.  “Make him promise not to bathe between certain hours.”

“That’s a good idea,” said Carson, smiling, “but after all I guess I’d better change the pipes.  Heaven forbid that in days like these I should seek to let any personal gratification stand between another man and the rare virtue of cleanliness.”

Several weeks went by, and men were busily employed in seeing that the water supply needed for a proper running of the organ came direct from the mains, instead of coming from a pipe of limited capacity used in common by a half dozen or more residents of a neighboring side street.

Somewhere about the end of the fourth week Carson invited me to dinner.  The organ was all right again, he said.  The water supply was sufficient, and if I cared to I might dine with him, and afterward spend an evening sitting upon the organ bench while Carson himself manipulated the keys.  I naturally accepted the invitation, since, in addition to his other delightful qualities, Carson is a past grand-master in the art of giving dinners.  He is a man with a taste, and a dinner good enough for him is a thing to arouse the envy of the gods.  Furthermore, as I have already said, he is a musician of no mean order, and I know of no greater pleasure than that of sitting by his side while he “potters through a score,” as he puts it.  But there was a disappointment in store for us.  I called at the appointed hour and found the household more or less in consternation.  The cook had left, and a dinner of “cold things” confronted us.
