"He's a professor, plumb-full of book dope on the Yukon. He's Mister Wise Mike. He knows it all. Hear his monologue on 'How It Should Be Done.' He's going to live on deck to inure himself to the rigours of the Arctic climate. Works with a pair of spring dumb-bells to get up his muscle so's he can shovel out the nuggets."

Our eyes roved round from group to group, picking out characteristic figures.

"See that big bleached-blond Englishman? Came over with me on the Pullman from New York. 'Awfully bored, don't you know.' When we got to 'Frisco, he says to me: 'Thank God, old chappie, the worst part of the journey's over.' Then there's Romulus and Remus, the twins, strapping young fellows. Only way I know them apart is one laces his boots tight, the other slack. They think the world of each other."

He swung around to where Salvation Jim was talking to two men.

"There's a pair of winners. I put my money on them. Nothing on earth can stop those fellows, native-born Americans, all grit and get-up. See that tall one smoking a cigar and looking at the women? He's an athlete. Name's Mervin; all whipcord and whalebone; springy as a bent bow. He's a type of the Swift. He's bound to get there. See the other. Hewson's his name; solid as a tower; muscled like a bear; built from the ground up. He represents the Strong. Look at the grim, determined face of him. You can't down a man like that."

He indicated another group.

"Now there's three birds of prey. Bullhammer, Marks and Mosher. The big, pig-eyed heavy-jowled one is Bullhammer. He's in the saloon business. The middle-sized one in the plug hat is Marks. See his oily, yellow face dotted with pimples. He's a phoney piece of work; calls himself a mining broker. The third's Jake Mosher. He's an out-and-out gambler, a sure-thing man, once was a parson."

I looked again. Mosher had just taken off his hat. His high-domed head was of monumental baldness, his eyes close-set and crafty, his nose negligible. The rest of his face was mostly beard. It grew black as the Pit to near the bulge of his stomach, and seemed to have drained his scalp in its rank luxuriance. Across the deck came the rich, oily tones of his voice.

"A bad-looking bunch," I said.

"Yes, there's heaps like them on board. There's a crowd of dance-hall girls going up, and the usual following of parasites. Look at that Halfbreed. There's a man for the country now, part Scotch, part Indian; the quietest man on the boat; light, but tough as wire nails."
