From within, through the open window, came the tinkling of Tom's _ukulele_ and the rollicking lilt of his voice in an Hawaiian _hula_. It ended in a throbbing, primitive love-call from the sensuous tropic night that no one could mistake. There was a burst of young voices, and a clamour for more. Frederick did not speak. He had sensed something vague and significant. Turning, he glanced through the window at Tom, flushed and royal, surrounded by the young men and women, under his Viking moustache lighting a cigarette from a match held to him by one of the girls. It abruptly struck Frederick that never had he lighted a cigar at a match held in a woman's hand. "Doctor Tyler says he oughtn't to smoke--it only aggravates," he said; and it was all he could say. As the fall of the year came on, a new type of men began to frequent the house. They proudly called themselves "sour-doughs," and they were arriving in San Francisco on the winter's furlough from the gold-diggings of Alaska. More and more of them came, and they pre-empted a large portion of one of the down-town hotels. Captain Tom was fading with the season, and almost lived in the big chair. He drowsed oftener and longer, but whenever he awoke he was surrounded by his court of young people, or there was some comrade waiting to sit and yarn about the old gold days and plan for the new gold days. For Tom--Husky Travers, the Yukoners named him--never thought that the end approached. A temporary illness, he called it, the natural enfeeblement following upon a prolonged bout with Yucatan fever. In the spring he would be right and fit again. Cold weather was what he needed. His blood had been cooked. In the meantime it was a case of take it easy and make the most of the rest. And no one undeceived him--not even the Yukoners, who smoked pipes and black cigars and chewed tobacco on Frederick's broad verandas until he felt like an intruder in his own house. There was no touch with them. They regarded him as a stranger to be tolerated. They came to see Tom. And their manner of seeing him was provocative of innocent envy pangs to Frederick. Day after day he watched them. He would see the Yukoners meet, perhaps one just leaving the sick room and one just going in. They would clasp hands, solemnly and silently, outside the door. The newcomer would question with his eyes, and the other would shake his head. And more than once Frederick noted the moisture in their eyes. Then the newcomer would enter and draw his chair up to Tom's, and with jovial voice proceed to plan the outfitting for the exploration of the upper Kuskokeem; for it was there Tom was bound in the spring. Dogs could be had at Larabee's--a clean breed, too, with no taint of the soft Southland strains. It was rough country, it was reported, but if sour-doughs couldn't make the traverse from Larabee's in forty days they'd like to see a _chechako_ do it in sixty.
