So engrossed was Smith that he did not notice the almost imperceptible withdrawal of his auditor. Among her Boston friends there was no one who spoke of prize fights; even Charles Wilkinson, whose conversational reservations were certainly few, ignored the prize ring. Smith went unconsciously on, but for his hearer, for the time at least, the spell was snapped. Still, she listened. He told her more of what the maps showed—how they indicated the location and size of the water mains in the streets, of the hydrants, the fire department houses, even the fire alarm boxes—everything, in short, which the fire underwriter desired to contemplate when passing on a risk submitted for the company's approval. By this time they had reached the other end of the big room and were close to O'Connor's office.

"I really must have taken you on a walk of several miles," said Smith, contritely; "and if you are going to let me continue this monologue, I may at least let you sit down. Suppose we go in here; Mr. O'Connor has just left town, and we may as well use his office."

Again Miss Maitland hesitated, although not sufficiently to attract her companion's notice. She was not accustomed to interviews in private offices with strange young men. But she entered, and Smith behind her, and the glass door closed on them both, shutting out the sound of the clicking typewriters. Helen seated herself with her back to the window.

"Go on," she said. "I want to hear everything."

Smith went on.

Briefly but clearly he sketched the foundations of insurance. How, in more primitive times, when a man's house burned, his neighbors used to provide him with materials and come to help him rebuild; but this proved onerous, and instead a communal fund for the purpose of assisting fire sufferers was established. The modern insurance company had gradually come to assume the management of this fund and eventually to undertake the function of insuring against fire. But the people were still the arbiters of the fire cost, and the companies merely barometrically reflected the condition of the community as to fires. When fires are numerous and costly, the price of insurance must advance. Insurance is a tax which the companies collect in premiums from the many and pay out in losses to the few. But the idea remains the same.

"That is interesting," said the girl. "Now will you think me very stupid if I ask you to explain what all the terms mean as you go along? You spoke a moment ago of underwriting: I don't know what underwriting is. I thought big loans and stock issues and things of that sort were underwritten. Is this the same?"

"So they are, but this is another matter. Fire underwriting is a thing all to itself—sui generis. Similarly, a fire underwriter is a person like no other—at all events he likes to persuade himself that he is. And frequently he succeeds."

Smith smiled at his own reflection.

"A fire underwriter, to be a real one," he went on, "should be a chemist, financier, mechanic, lawyer, engineer, and diplomat, and a dash of a clairvoyant, too. He should know everybody's business, including his own. Consider what he is expected to know: there is no class of industry which can dispense with insurance."
