The women were now making a canoe under Godfrey's instructions. He had often gone out in canoes on the Severn and on the sea when staying at watering-places there. The craft that had done them such good service before would not do for their present undertaking. They required a boat which should be fairly fast, sea-worthy, and yet light, for it might be necessary to carry it considerable distances. It was necessary that its dimensions should exceed those of an English canoe, for it must carry a considerable amount of food, although of course he meant to depend chiefly on the fishing-lines and gun. It was made five-and-twenty feet long, and three feet wide. The central compartment was thirteen feet long. This was covered in at the sides and ends, leaving an opening for them to sit and paddle, fifteen inches wide, and five feet long. Underneath the covered parts provisions, furs, cooking utensils, &c., could be stowed away on both sides, leaving room for them to lie down at full length in the centre.

The two end compartments were entirely covered in, but had openings over which a cover was lashed, and could, if necessary, be used for holding stores; but Godfrey did not intend to put anything here except temporarily, as it was important that the canoe should be as buoyant and light as possible. The frame of the boat was built of the tough and elastic wood of which the Ostjaks made their bows. It was very light, the ribs being bound to the longitudinal pieces by fine gut. It was built, as nearly as Godfrey could lay them out, on the lines of an English cruising canoe. The deck strips were similarly lashed, and when the framework was completed Godfrey tested its strength by dropping it three feet to the ground, rolling it over and over, and trying it in a variety of ways.

When fully satisfied with it the work of putting on the cover commenced. This was made of very soft and well-tanned reindeer hide, stretched as tightly as possible, and then rubbed with seal oil. The keel of the boat had been made very strong, as the rigidity of the whole craft depended upon this. It had been made flat, and the skins had been taken over it. When it was finished a false keel six inches in depth in the centre, tapering away to nothing at the ends, was fixed underneath. This keel was also made of tough wood, a little more than a quarter of an inch thick, but widening suddenly to over an inch where it touched the boat, in order that it might be securely fixed with screws to the keel inside.

The boat was provided with a light mast, which could be stepped or unstepped at pleasure, and there were two stays of twisted leather, one fastening to each side of the boat. An iron ring with a cord travelled up and down the mast, the halliard running through a small block, as Luka had been able to obtain a sheave at Turukhansk. The sail was a lug made of sheeting, oiled, and the boat carried beside a triangular sail of very much smaller dimensions and stouter cloth for heavy weather. She also carried a small mizzen mast and sail. In rough weather the cockpit could be completely covered with a light apron with openings where the rowers sat, with a sort of collar, which could be lashed tightly round their waists. The edges of this apron could be lashed down over the gunwale round the cockpit. When completed the canoe itself, with its mast and sails, weighed but sixty pounds, and could be carried with ease by one person on his shoulder.

The Ostjaks greatly admired the craft, which was entirely different from anything they had ever seen. The false keel puzzled them greatly, and Godfrey's explanations, even when aided by Luka, failed altogether in making them understand that it would have the effect of enabling the craft to sail near the wind without drifting to leeward. The additional draught of water was no inconvenience whatever in a craft designed for the sea, and it added materially to the strength of the canoe. On the 15th of May it was freezing hard. The natives going down to the water's edge in the morning reported a sudden rise of three feet in the river. It continued to rise all day, and by nightfall was fifteen feet above its former level.

In the evening the north wind dropped suddenly, and an hour later it sprang up from the south, and by midnight a torrent of rain was falling. Godfrey could hear sounds like the reports of cannon above the pattering of the rain on the skins, and knew that it must be the ice breaking. In the morning when he looked out the whole mass of ice seemed to be moving. Black cracks showed everywhere across the white surface. The river had during the night risen another twenty feet. By mid-day the scene was a wild one indeed. No longer was the surface smooth. Hurrying along at the rate of fifteen miles an hour the great masses of ice were dashed against each other by the force of the current.

Two miles lower down the river narrowed suddenly, and here a block was formed. Some of the pieces of ice were thrust down, others climbed over them, thrusting themselves one on the top of the other till a ridge thirty or forty feet high was formed from bank to bank. At times this gave way, and then the whole was whirled down the stream, while another ridge at once commenced to form. Godfrey walked down to the point and stood for hours looking at the scene. The great blocks of ice, six or eight feet thick, seemed almost to be endowed with vitality as they climbed one above the other, until thrust off the crest of the ridge by the pressure of those behind them. The din was prodigious, a crackling, rustling, roaring sound, with sharp explosions and deep muffled booming. The whole air seemed to quiver with sound, and the loudest shout would have been inaudible a yard or two away. Below the ridge the river, so long as the barrier stood, was comparatively clear, but from time to time great masses of ice that had been sunk by the pressure and swept along under the ridge came to the surface with a surge that lifted one end high out of the water, reminding Godfrey of the spring of some enormous fish; then the ice would come down with a mighty splash, and hasten away reeling and rocking on the rapid current. Entranced by this mighty conflict of the forces of nature, Godfrey stood there until seven or eight o'clock in the evening.

It would be light for three hours yet, for the sun now only sank for a short time below the horizon. The rain was still falling heavily when he returned to his hut. The river had risen another thirty feet since the evening before, and the height of the bank had decreased from a hundred feet to about thirty. For two more days it rained incessantly. The river had now risen to its high-water mark, ten feet below the bank. Godfrey asked the Ostjaks if there was no fear of its overflowing, but they told him that there was no cause for uneasiness, for that at its present point it overflowed at many places both above and below them, and extended over a vast tract of country, and that at every additional foot it would spread so widely that it would speedily begin to fall again. The ridge had now ceased to form, although the river was still packed with floating masses.

"In another two days," the Ostjaks' chief said, "the ice will be all gone except a few blocks. Much of the ice above is carried out by the floods and left to melt on the land as the water lowers, but even without that the river at its present rate would soon carry it all down."

This Godfrey could well imagine, for at the rate of fifteen miles an hour over three hundred and sixty miles of the river would have been emptying daily. At the end of another three days but few blocks of ice were visible, and Godfrey now began to make preparations for his start. First the canoe was to be tried. She was taken down and placed in the water, and the sides under the half-decks were filled in with frozen geese and fish from the pile, which was still but little affected by the thaw.
