Chester and Ivan nodded.

CHAPTER XXIX.

MR. STUBBS PROVES HIMSELF.

"We'll stay in among the trees and won't show ourselves unless we have
to," Hal explained.

From the direction in which the fugitives had so recently come, there now
came the noise of a rapidly approaching body of horsemen. They halted a
short distance from where Hal, Chester and Ivan stood and dismounted.

"They may be hiding in here," said a voice. "We'll have a look."

The men, a dozen of them, came forward.

Making a slight detour, the three friends managed to get behind them.
Then, instead of continuing straight ahead, Hal turned sharply in his
tracks and followed in the wake of the Bulgarian searching party.

The Bulgarians proceeded slowly, exploring every nook and corner of the
woods, and firing their rifles into the densest of the trees. Hal,
Chester and Ivan came up with them at length and mingled among them
without being discovered.

"Off to the left farther," instructed the officer in command.

"No use," said Hal, in a gruff voice. "I've just come from there. There
is no one there. The fugitives must have gone farther."

"Are you sure?" asked the officer, looking at the lad searchingly.

"Positive. I fired my revolver into every tree in which I thought there

of being detected. They all walked slowly and gradually were left behind.

The Bulgarians mounted and rode off down the road.

"Well, we are safe for a few minutes," said Chester, drawing a breath of
relief. "What now, Hal?"

"Well," was the reply. "We can't fool about in these woods long. We are
bound to be found sooner or later if we do. Also, there is little chance
that we could walk to the Greek frontier without being discovered. In
some way we must find a conveyance."

"Yes, but how?" questioned Chester.

"That's the question. But certainly some of these Bulgarian officers must
have motor cars. Surely they have some means of transportation besides
horses. I have an idea that if we will follow them, in their search, we
may come across an automobile."

"That's not a half bad idea," declared Chester. "We'll do it. Shall we
start now?"

"Hold on," said Hal. "Either you or I must remain h
