Leaving all our impedimenta to be shipped by rail, that is, Bill, the tent, extra blankets, phonograph—everything but a few cooking-utensils, an ax, a tarp, and a pair of blankets—the Kid and I got in with the little man and dropped down to the Yellowstone. The new boat was moored under a mud bank. I climbed in, lit a match, and my heart leaped with joy. She was staunch and beautiful—a work of love, which means a work of honesty. Fore and aft were air-tight compartments. She had an oil tank, a water tank, engine housing, steering wheel, lockers. She was ready for the very engine I had ordered to be shipped to me at Bismarck. She was dry as a bone, and broad enough to make a snug bed for two.

The little man and the motor boat dropped out into the gloom and left us gloating over our new possession, sending thankful rings of tobacco smoke at the stars. When the first flush of triumph had passed, we rolled up in the bottom of the boat, lulled to sleep by the cooing of the fusing rivers, united under our gunwale. Such a sleep—a dry sleep! and the sides of the boat protected us against the chill night wind.

And the dawn came—shouting merrily like a boy! I once had a chum who had a habit of whistling me out of bed now and then of a summer morning, when the birds were just awakening, and the dew looked like frost on the grass. And the sun that morning made me think of my old boy chum with his blithe, persistent whistling. For the first hard stage of the journey was done; all had left me but a brave lad who would take his share of the hardships with a light heart. (All boys are instinctively true sportsmen!) And before us lay the great winding stretch of a savage river that I had loved long—the real Missouri of my boyhood.

A new spirit had come upon us with the possession of the Atom II—the spirit of the forced march. For nearly a month we had floundered, trusting to a sick engine and inefficient paddles. Now we had a staunch, dry boat, and eight-foot oars. We trusted only ourselves, and we were one in the desire to push the crooked yellow miles behind us. During the entire fourteen hundred miles that desire increased, until our progress was little more than a retreat. We pitched no camps; we halted only when we could proceed no further owing to sandbars encountered in the dark; we ate as we found it convenient to do so. Regularly relieving each other at the oars, one sat at the steering wheel, feeling for the channel. And it was not long until I began to note a remarkable change in the muscles of the Kid, for we toiled naked to the waist most of the time. His muscles had shown little more than a girl's when we first swam together at Benton. Now they began to stand out, clearly defined, those of his chest sprawling rigidly downward to the lean ribs, and little eloquent knots developed on the bronzed surface of his once smooth arms. He was at the age of change, and he was growing into a man before my eyes. It was good to see.

All the first day the gods breathed gently upon us, and we made fifty miles, passing Trenton and Williston before dark. But the following day, our old enemy, the head wind, came with the dawn. We were now sailing a river more than twice the size of the Upper Missouri, and the waves were in proportion. Each at an oar, with the steering wheel lashed, we forged on slowly but steadily. In midstream we found it impossible to control the boat, and though we hugged the shore whenever possible, we were obliged to cross with the channel at every bend. When the waves caught us broadside, we were treated to many a compulsory bath, and our clothes were thoroughly washed without being removed. An ordinary skiff would have capsized early in the day, but the Atom II could carry a full cargo of water and still float.

By sunset the wind fell, the river smoothed as a wrinkled brow at the touch of peace. Aided by a fair current, we skulled along in the hush of evening through a land of vast green pastures with "cattle upon a thousand hills." The great wind had spread the heavens with ever deepening clouds. The last reflected light of the sun fell red upon the burnished surface of the water. It seemed we were sailing a river of liquefied red flame; only for a short distance about us was the water of that peculiar Missouri hue which makes one think of bad coffee colored with condensed milk.

Slowly the colors changed, until we were in the midst of a stream of iridescent opal fires; and quite lost in the gorgeous spectacle, at length we found ourselves upon a bar.

We got out and waded around in water scarcely to our ankles, feeling for a channel. The sand was hard; the bar seemed to extend across the entire river; but a thin rippling line some fifty yards ahead told us where it ended. We found it impossible to push the heavy boat over the shallows. The clouds were deepening, and the night was coming rapidly. Setting the Kid to work digging with an oar at the prow, I pushed and wriggled the stern until I saw galaxies. Thus alternately digging and pushing, we at last reached navigable depths.

It was now quiet and dark. Low thunder was rolling, and now and then vivid flashes of lightning discovered the moaning river to us—ghastly and forbidding in the momentary glare. We decided to pull in for the night; but in what direction should we pull? A drizzling rain had begun to fall, and the sheet lightning glaring through it only confused us—more than the sooty darkness that showered in upon us after the rapid flashes. We sat still and waited. In the intermittent silences, the rain hissed on the surface of the river like a shower of innumerable heated pebbles. Ahead of us we heard the dull booming of the cut banks, as the current undermined ponderous ledges of sand.

Now, a boat that happens under a falling cut bank, passes at once into the region of forgotten things. The boat would follow the main current; the main current flows always under the cut banks. How long would it take us to get there? Which way should we pull? Put a simpler question: In which way were we moving? We hadn't the least conception of direction. For us the night had only one dimension—out!
