the craft higher up, made it dip down almost to the earth, and then swoop upward like some great bird. Then he turned it completely about and though he developed no great speed in this test made it progress quarteringly against the wind,
"It's almost perfect," declared Tom. "A few touches and she'll be all right."
"Is it all right?" asked Ivan Petrofsky anxiously, as the three left the cabin, and Eradicate hitched his mule to the glider to take it back to the shed.
"I see where it can be improved," he said, as they made ready to descend. "I'll soon have it in shape."
"Then we can go to Siberia?"
"In less than a month. The big airship needs some repairs, and then we'll be off."
The Russian said nothing, but he looked his thanks to Tom, and the manner in which he grasped the hand of our hero showed his deep feelings.
The glider was given several more trials, and each time it worked better. Tom decided to change some of the weights, and he devoted all his time to this alteration, while Ned, Mr. Damon, and the others labored to get the big airship in shape for the long trip to the land of the exiles.
