Next day at early dawn, Hatteras gave the signal for departure. The well-fed and well-rested dogs were harnessed to the sledge. They had been having a good time of it all the winter, and might be expected to do good service during the summer.

It was six in the morning when the expedition started. After following the windings of the bay and going past Cape Washington, they struck into the direct route for the north, and by seven o’clock had lost sight of the lighthouse and Fort Providence.

During the first two days they made twenty miles in twelve hours, devoting the remainder of the time to rest and meals. The tent was quite sufficient protection during sleep.

The temperature began to rise. In many places the snow melted entirely away, and great patches of water appeared; here and there complete ponds, which a little stretch of imagination might easily convert into lakes. The travellers were often up to their knees, but they only laughed over it; and, indeed, the Doctor was rather glad of such unexpected baths.

“But for all that,” he said, “the water has no business to wet us here. It is an element which has no right to this country, except in a solid or vaporous state. Ice or vapour is all very well, but water — never!”

Hunting was not forgotten during the march, for fresh meat was a necessity. Altamont and Bell kept their guns loaded, and shot ptarmigans, guillemots, geese, and a few young hares; but, by degrees, birds and animals had been changing from trustfulness to fear, and had become so shy and difficult to approach, that very often, but for Duk, the hunters would have wasted their powder.

Hatteras advised them not to go more than a mile away, as there was not a day, nor even an hour, to lose, for three months of fine weather was the utmost they could count upon. Besides, the sledge was often coming to difficult places, when each man was needed to lend a helping hand.

On the third day they came to a lake, several acres in extent, and still entirely frozen over. The sun’s rays had little access to it, owing to its situation, and the ice was so strong that it must have dated from some remote winter. It was strong enough to bear both the travellers and their sledge, and was covered with dry snow.

From this point the country became gradually lower, from which the Doctor concluded that it did not extend to the Pole, but that most probably this New America was an island.

Up to this time the expedition had been attended with no fatigue. The travellers had only suffered from the intense glare of the sun on the snow, which threatened them with snow-blindness. At another time of the year they might have avoided this by walking during the night, but at present there was no night at all. Happily the snow was beginning to melt, and the brilliancy would diminish as the process of dissolution advanced.

On the 28th of June the thermometer rose to 45°, and the rain fell in torrents. Hatteras and his companions, however, marched stoically on, and even hailed the downpour with delight, knowing that it would hasten the disappearance of the snow.

As they went along, the Doctor often picked up stones, both round ones and flat pebbles, as if worn away by the tide. He thought from this they must be near the Polar Basin, and yet far as the eye could reach was one interminable plain.

There was not a trace of houses, or huts, or cairns visible. It was evident that the Greenlanders had not pushed their way so far north, and yet the famished tribes would have found their account in coming, for the country abounded in game. Bears were frequently seen, and numerous herds of musk-oxen and deer.

On the 29th, Bell killed a fox and Altamont a musk-ox. These su............
