Reuben listened approvingly to it all, and, when he had finished, mildly asked:

"How much longer shall we stay here, Seth? We've about seen all there is to see. Had we not better be starting back?"

"To be sure we had," replied Seth, whose enthusiasm over the possibility of successfully attacking the fort had caused him to be oblivious of the flight of time. "Come along; we mustn't stay here any longer."

Just as they were about to start they saw a party set out from the fort on skates and speed away southward.

"Whew!" exclaimed Seth. "I wonder what that means. Are they going off to do a little scouting on their own account? In that case we'll have to keep a sharp lookout or we may fall into their hands."

There was certainly need for using the utmost precaution in their movements, and it was with a keener sense of danger than they had felt before that the two New Englanders began their return journey.

So long as they were concealed by the woods they were safe enough from discovery, but once they took to the ice, which they must do as soon as possible, for their provisions were running low, and would not by any means last for a long journey overland, then they ran the risk of being sighted and pursued.

But there was no help for it, and no time to be lost, so they urged their way through the forest until they reached the edge of the lake.

Then with eager eyes and fast-beating pulses they scanned the glistening surface before them. Not a living thing was in view, but at any moment from around one of the wooded points the enemy might appear.

"I wish I knew which side they're on," said Seth, the anxious expression of his countenance showing his state of mind. "The farther away we can keep from them the better chance we'll have, for I'm sure we can skate as fast or faster than any of them."
