The course of the first battalion of the Riverlawn Cavalry was along a path scarcely wide enough for four horsemen to ride abreast. It was through a thicket of dwarf trees, the limbs of which took off many a hat and scratched hands and faces. At several points the riders came to hollows, filled with icy water, and here detours had to be made, for fear the animals might become stuck in the stiff soil beneath.

As was his usual habit, Deck rode at the head of his command, with Captain Abbey, of the first company, beside him. Several scouts had been sent out and with them had gone Artie Lyon, by special permission of the major.

The scouts soon found the road making a broad sweep to the south, and presently came to a point where there was a clearing in the woods and a brook. Here they stopped their horses for a drink, and Artie pointed out some fresh tracks leading up the watercourse. The tracks were of men as well as horses.

"Let us investigate those tracks," he said to Lieutenant Fronklyn, who was one of the party. "I think they are about what we are looking for."

"I wouldn't be surprised," answered Fronklyn, who, as old readers know, had frequently been on the scout with Deck, and he knew a thing or two about the business. "Do we go afoot, Captain?"

"I think we had better."

The horses were tethered in the brush, and the pair advanced along the brook with caution. Soon the trail led to the westward, and here they found themselves confronted by a series of rocks, overgrown by moss and covered with dead leaves. Fronklyn stopped and scratched his head.

"Are we stumped?" questioned Artie. He got down on his knees and commenced to examine the moss. "I reckon we can follow the trail in spite of the rocks. Come ahead," and again they advanced.

The rocks ran up and then down. At the other side was another clearing, and not far away the regular road to Rover.

"Halt!" whispered Artie, catching his companion by the arm. "There they are, as sure as guns!" and he pointed to their left.
