They retired early to rest, for they needed to be up betimes. So passed the last night in Fort Providence.

CHAPTER XIX.

MARCH TO THE NORTH

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!"
