Affairs for the Keiths passed through another week of what might be called the transition stage. It took them that long to settle down in their new house and into some semblance of a routine--two days to the actual installation, and the evenings full of small matters to arrange. Nan was busy all day long playing with her new toy. The housekeeping was fascinating, and Wing Sam a mixture of delight and despair. Like most women who have led the sheltered life, she had not realized as yet that the customs of her own fraction of one per cent, were not immutable. Therefore, she tried to model the household exactly in the pattern of those to which she had been accustomed. Wing Sam blandly refused to be moulded.

Thus Nan spent all one morning drilling him in the proper etiquette of answering doors. Mindful of John McGlynn's advice, she did this by precept, ringing her own door bell, presenting a card as though calling on herself. Wing Sam's placid exterior changed not. A half hour later the door bell rang, but no Wing Sam appeared to answer it. It rang again, and again, until Nan herself opened the door. On the doorstep stood Wing Sam himself.

"I foolee you, too," he announced with huge delight.

Painstakingly Nan conveyed to him that this was neither an amusing game nor a practical joke. Later in the day the door bell rang again. Nan, hovering near to gauge the result of her training, saw Wing Sam plant himself firmly in the opening.

"You got ticket?" he demanded sternly of the deliveryman outside. "You no got ticket, you no get in!"

Which, Nan rather hysterically gathered, was what Wing Sam had gained of the calling-card idea. After that, temporarily as she thought, Nan permitted him to go back to his own method, which, had she known it, was the method of every Chinese servant in California. The visitor found his bell answered by a blandly smiling Wing Sam, who cheerfully remarked: "Hullo!" It was friendly, and it didn't matter; but at that stage of her development Nan was more or less scandalized.

Nan's sense of humour always came to her assistance by evening, and she had many amusing anecdotes to tell Keith, over which both of them laughed merrily. Gringo added somewhat to the complications in life. He was a fat, roly-poly, soft-boned, ingratiating puppy, with a tail that waved energetically but uncontrolledly. Gringo at times was very naughty, and very much in the way. But when exasperation turned to vengeance he had a way of keeling over on his back, spreading his hind legs apart in a manner to expose his stomach freely to brutal assault, and casting one calm china- blue eye upward.

"Can there anywhere exist any one so hard-hearted as to injure a poor, absolutely defenceless dog?" he inquired, with full confidence in the answer.

The iniquities of Gringo and the eccentricities of Wing Sam Nan detailed at length, and also her experiences with the natives. She as yet looked on every one as natives. Only later could she expand to the point of including them in her cosmos of people. Nan was transplanted, and her roots had not yet struck down into the soil. In her shopping peregrinations she was making casual acquaintance, and she had not yet become accustomed to it.

"I bought some darling little casseroles at Phelan's to-day," she said. "The whole Phelan family waited on me. Where do you suppose the women get their perfectly awful clothes? Mrs. Phelan offered to take me to her milliner!" or "You know Wilkins--the furniture man where we got the big armchair? I was in there to-day, and he apologized because his wife hadn't called!"

They went to bed early, because they were both very tired.

Keith also had generally passed an interesting day. Immediately after breakfast he went to his office, and conscientiously sat a while. Sometimes he wrote letters or cast up accounts; but there could not be much of this to do. About ten or eleven o'clock his impatient temperament had had enough of this, so he drifted over to the Monumental engine house. After considerable thought he had decided to join this company. It represented about the class of men with whom he wanted to affiliate himself--the influential men of the lawyer, Southern-politician, large business men type. There were many of these volunteer organizations. Their main purpose was to fight fire; but they subserved other objects as well--political, social, and financial. David Broderick, for example, already hated and feared, partly owned and financed a company of ward-heelers who were introducing and establishing the Tammany type of spoils politics. Casey, later in serious trouble, practically manipulated another.

Among the Monumentals, Keith delighted especially in Bert Taylor. Bert Taylor likewise delighted in Keith. The little chubby man's enthusiasm for the company, while recognized as most valuable to the company's welfare, had ended by boring most of the company's members. But Keith was a new listener and avid for information. He had had no notion of how complicated the whole matter could be. Bert Taylor dissertated sometimes on one phase of the subject, sometimes on another.

"It's drills we need, and the fellows won't drill enough!" was Bert Taylor's constant complaint. "What do they know about hose? They run it out any way it comes; and roll it up anyhow, instead of doing a proper job."

"How should you do it?" asked Keith.

"It ought to be laid right--so there's no bends or sharp angles in it; it should never be laid over heaps of stones, or any kind of uneven surface-- it all increases the water resistance. If there are any bends or curves they should be regular and even. The hose ought never to rest against a sharp edge or angle. And when you coil it up you ought to reverse the sides every time, so it will wear even and stretch even. Do they do it? Not unless I stand over them with a club!"

He showed Keith the hose, made of India rubber, a comparatively new thing, for heretofore hose had been made of riveted leather. Bert Taylor made him feel the inside of this hose with his forefinger to test its superlative smoothness.

"Mighty little resistance there!" he cried triumphantly.

The nozzles, all in racks, he handled with almost reverent care.

"These are the boys that cost the money," said Taylor. "If the inside isn't polished like a mirror the water doesn't come smooth. And the least little dent makes the stream ragged and broken. Nothing looks worse--and it isn't as effective on the fire. It ought to be thrown like a solid rod of water. I can't get the boys to realize that the slightest bruise, dent, or burr throws the stream in a ragged feathery foam. The result of that is that a lot of water is dissipated and lost."

Keith, who had taken hold of the nozzle rather negligently, returned it with the reveren............
