“Never mind your glacier,” shouted Nimbus. “I’ve found the track of the Evening Star, and she is going east instead of north.” He had climbed up a crevice in one of the ice cliffs and was studying the surface of a thin covering of new-fallen snow. There before him were the dainty footprints of the Evening Star, and here and there a blossom apparently fallen from her bouquet lay scattered along the tracks. “Now,” said Nimbus, “we will separate. Billy, you and I will go after the Evening Star, and you, Jack Frost, can follow the open trail of the Equator and see if you can find him. If you do find him, be sure not to let him get away.” “How about us?” said the motorman severely. “Oh, I had forgotten you!” said Nimbus. “We hadn’t,” said the motorman. “Then you’d better,” said the Equine Ox, sticking his head out of one of the windows of the car. “Always remember yourself last.” “I don’t care to hear anything more from you,” said the motorman. “It’s against the rules for a beast to talk, anyway.” “Oh, I don’t know about that!” said a voice from a little peak just above them. “A bear,” said Billy, astonished. “Why not?” said the voice, as a great white Polar Bear threaded his way down the slope toward the trolley car. But the motorman and the conductor seemed to think there were many reasons why not. They hastily sought shelter inside the car and closed the door after them, while the Equine Ox, with a snort of terror, pulled his head in so quickly that he brought away a part of the sash with his horns. “My!” said Billy; “I’m afraid that bear will get them or us.” “He’ll have to eat the side of the trolley car before he gets them,” said Nimbus. “And by that time,” added Jack Frost, “he’ll be so full he won’t have any more room for them.” So, leaving the bear busily gnawing at the sash board of the car, Nimbus, Jack Frost and Billy proceeded afoot on their quest. Jack Frost set out on the Equator’s trail at a prodigious pace, muttering to himself at each fresh discovery of a ruined glacier or melted icefield. Billy and Nimbus proceeded more slowly, for the track of the Evening Star was not always distinct, and it was plain that, here and there, when the going was hard, she had sailed over the obstructing cliffs. At the end of an hour the track disappeared altogether, nor could they find it, search as they might. “Where do you suppose she has gone?” inquired Billy. “Up,” said Nimbus briefly. “Probably saw the Equator coming.” As he was speaking they heard a familiar voice, and Jack Frost hailed them. “Hello!” said Nimbus; “what are you doing over here?” “This is where the track brought me,” replied Jack Frost, and Billy and Nimbus saw that the trail through the snow which had been melted by the Equator was within a few yards of them. “That explains why the Evening Star stopped walking,” said Nimbus. “She saw the Equator headed over this way, and decided she had better travel a little faster.”
