The steamboat Selkirk, which was to carry the boys from White Horse to Circle City, was of the old time kind that was used on the Mississippi and other rivers half a century ago; that is, it was of the wood-burning, stern paddle-wheel type.

As they stood out on deck the next morning Jack tried to lose sight of the big issue for the moment and he imagined himself to be the first explorer who had traced the Yukon River in this region. If he had not had gold on the brain it would have been an easy thing to do for here were the same virgin meadows, primeval forests and silent fastnesses just as they were when the Russians laid claim to Alaska. And the gold, he reasoned, that was here then is, for the greater part, here now.

Not once since they had left Seattle had Bill compared anything with his Noo York, at least not out loud, but when they were passing through the headwaters of the Yukon he said as though he was talking to himself, “It hasn’t got anything on the Spuyten Duyvil,” which, let me elucidate, is a tidal channel that connects the Harlem River with the Hudson River and so forms the northern boundary of Manhattan Island on which New York City proper is built. But in the eight hundred and sixty odd mile trip down the Yukon to Circle City Bill had ample opportunity to amend his snap comparison and even then he was fifteen hundred miles from its many channeled delta where it flows into the Bering Sea.

“Doesn’t look much like the naked north or frozen regions that the folks back home think it is,” remarked Bill, as they passed a tundra (pronounced toon´-dra) which was thick with grass and shrubs and sprinkled with various plants in flower.

“I’ll say it doesn’t,” replied Jack, “but wait, we haven’t run into winter weather yet.”

As the boat plied its way softly and swiftly down the Yukon they saw occasional Indian villages, the men taking life easy, the children playing and the squaws busy drying the golden salmon on poles set in the sun. Then to the great delight of both boys they saw a caribou swim out from the shore intending, probably, to cross to the other side, but frightened by the modernity of the throbbing, smoking monster he swam back faster than he came, and on gaining the shore he disappeared from view.

Another time Bill went over to Jack, who was talking with some passengers, and saluting as to an officer he said, “I have to report, sir, a bear on the starboard bow.” And sure enough there stood a huge bear high on the ledge of a rock and so motionless was he that he seemed carved out of the rock itself; but inwardly he was fully alive to this mechanical invasion of his eminent domain.

Never was a river trip of such wild beauty, so full of interest and yet such soothing quiet as this one the boys were now making and it would have proved doubly delightful if they had been pleasure seekers instead of gold seekers. The only breaks in the continuity of the run were made when the boat nosed its way along a bank and, finding an anchorage, she wooded up, that is she took on wood to be burned under her boilers.

Now the river widened and the boat ran into the more placid waters of Lake LeBarge which Jack pointed out to Bill as having been the scene of action in The Cremation of Sam McGee, a poem by Robert Service. On reaching the lower end of the lake the boat shot down the Thirty Mile River where the swift current winds forth and back like a tangled rope and it takes a pilot who knows his trade to hold her to the channel.

But the most exciting piece of navigation is at Five Finger Rapids, for here the river narrows down into a neck and almost closing the latter are five ugly finger-like rocks projecting above the surface with the water swirling swiftly round them in mighty eddies. It looked to Jack and Bill as if there was not enough room for the boat to pass between any two of them but this didn’t seem to worry the pilot any who held her nose hard toward the middle finger.
