“Come over, Baldy! Back, Ginger!”

The polers are hooked up, and in a short space the wagon moves off to the Signal office for final instructions. Gunner jumps down from the body of the wagon, drags the end of the wire into the Signal office, and then mounts and pulls out over the hill.

The wagon rolls steadily over the rocky hills, reeling out the cable as it proceeds. Darkness settles down, but this does not deter the cable detachment.

“Whoa!” roars the lead driver as a wady-bed opens up below him in the darkness. “Steady with those horses behind—who’s in the pole?”

“What’s the matter?” inquires Dawk, riding up to the leaders.

“Oh, another wady; it looks pretty solid, too.”

Dawk looks ahead, rides off to the right, and after a few minutes calls out directions to the drivers.

“This way with that wagon; you can get across here.”

Charlie swings his leaders round and heads for the spot where Dawk’s voice is heard. The wagon jolts over a rock, and lurches toward the wady so closely that a huge lump of earth detaches itself from the steep bank and rattles down on to the boulders beneath.

“Get over to the right!” yells Gunner from the back of the wagon. “What the blazes are you drivers doing? You’ll have the whole box and dice in the wady in a minute!”
