As they traveled other circumstances arose to puzzle them. Once a flight of strange birds passed far above them, flying in the same direction. They came to a spot where the strangers had made camp, and there were the remains of a fire with charred wood. Then as they drew nearer, with many miles passed, they saw that the haze which hung about the mountain summits appeared to be not of clouds, but of smoke.
On the second stage of their journey Polaris halted the dogs at a new wonder.
"Lady," he said, "look hard and tell me the color of those hills, or is it that my eyes are giving way to the snow blindness?"
Rose Emer arose in the sledge and gazed at the hills, and cried: "Green! Green! But how can they be?"
"Warm air, green hills, and people with horses," Polaris smiled. "It seems that such are not all in the north. Ah, the good green hills I have read of and which I have so longed to see!"
On sped the dogs, and nearer and nearer loomed the hills of green, set like immense, dull emeralds in the white of the snows. Only at their summits were they black and craggy and scarred. Above them spiraled shifting clouds of smoke.
And as they journeyed, the sun shining on the softening snows, and the air growing warmer and warmer, in an ice-locked sound five hundred miles to the north, a little company of weary-faced men gathered on the deck of the good ship Felix, and one of their number read the burial service for the repose of Rose and John Emer and Homer Burleson, strayed from the ship and given up for dead after a searching party had failed to find any trace of them.
As the travelers neared the base of the foot-hills of the mountain range the ground became more uneven, being broken by rock slopes and small hills, many of which were bare of snow. Around these the trail wound zigzag. They swung around one of the sharp curves, and Polaris reined in the dogs.
"Now, lady, here comes one along the trail who may solve for us all our riddles!" he cried, and pointed ahead.
