Where the two rivers join, even at low water, the Yellowstone pours a vast turbulent flood, compared with which the clear and quieter Missouri appears an overgrown rain-water creek. The Mississippi after some miles obliterates all traces of its great western tributary; but the Missouri at Buford is entirely lost in the Yellowstone within a few hundred yards. All of the unique characteristics by which the Missouri River is known are given to it by the Yellowstone—its turbulence, its tawniness, its feline treachery, its giant caprices.

Examine closely, and everything will take on before your eyes either masculine or feminine traits. Gender, in a broad sense, is universal, and nothing was created neuter. The Upper Missouri is decidedly female: an Amazon, to be sure, but nevertheless not a man. Beautiful, she is, alluring or terrible, but always womanlike. But when you strike the ragged curdling line of muddy water where the Yellowstone comes in, it is all changed. You feel the sinewy, nervous might of the man.

So it is, that when you look upon the Missouri at Kansis City, it is the Yellowstone that you behold!

But names are idle sounds; and being of a peace-loving disposition, I would rather withdraw my contention than seriously disturb the geographical status quo! Let it be said that the Upper Missouri is the mother and the Yellowstone the father of this turbulent Titan, who inherits his father's might and wonder, and takes through courtesy the maiden name of his mother. There! I am quite appeased, and the geographers may retain their nomenclature.

At Mondak, Luck stood bowing to receive us. The Atom I had suffered more from contact with snags and rocks than we had supposed. For several hundred miles her intake of water had steadily increased. We had toiled at the paddles with the water halfway to our knees much of the time; though now and then—by spasms—we bailed her dry. She had become a floating lump of discouragement, and still fourteen hundred miles lay ahead.

But on the day previous to our sailing, a nervous little man with a wistful eye offered us a trade. He had a steel boat, eighteen feet long, forty inches beam, which he had built in the hours between work and sleep during the greater part of a year.

His boat was some miles up the Yellowstone, but he spoke of her in so artless and loving a manner—as a true workman might speak—and with such a wistful eye cast upon our boat, that I believed in him and his boat. He had no engine. It was the engine in our boat that attracted him, as he wished to make a hunting trip up river in the fall. He stated that his boat would float, that it was a dry boat, that it would row with considerable ease. "Then," said I, "paddle her down to the mouth of the Yellowstone, and the deal is made." After dark he returned to our camp with a motor boat, ready to take us to our new craft, Atom II.
