him, we can next dig up whatever it is that this foreign agent thinks
is worth burying!"

Then, with a shade of curiosity, Benson added to himself:

"I don't know, yet, how it happened that Hal was on my trail. There
wasn't time for him to tell me."

Clank! clank! But after a while the noise of the shovel ceased for a
while. Captain Jack craned his neck eagerly, trying to pierce the
darkness of the night. He could make out nothing, though he heard
some one still moving inside the clump of bushes.

Then again the noise of the shovel on the dirt was heard.

"He's filling in, now, beyond a doubt," thought Captain Jack. "He is
burying--what? The maps and records? Hiding them here that he may
dig them up at some later date?"

Benson chuckled noiselessly.

"If that's Millard's game I reckon some one else will do some digging
over yonder before he pays this place a second visit!"

Ah, the noise had stopped, at last. Now, Millard came out of the
thicket.

"He hasn't that bundle he brought up here!" throbbed Jack Benson. "And
he isn't bringing a shovel out, either, so it must be hidden right handy.
Great!"
