“We go right or we go left, Chuba?” Muscles asked.

“We’ll go straight up,” Biff replied. “Let’s see what’s on top. Surely can’t tell from here. After we take a look-see, we’ll probably bear to the right. Jaraminka must be off that way.” Biff pointed slightly to the northeast. “Think so, Chuba?”

Chuba nodded his head.

They mounted toward the rim at the top of the sharp incline. In places, the ground rose so sharply they had to pull themselves up, grabbing the stunted trees for handholds.

Nearing the top, they ran into a barrier that stopped them cold. This was a man-made obstacle, the last thing to expect in this wild, remote country. It was a heavy, metal-barred fence. It stood higher than Muscles’ head, and three strands of ugly barbed wire were stretched along the top.

“What the—” Muscles’ eyes bugged out in astonishment.

The fence stretched out to the right and left in a long curve. The ground was cleared on both sides of the fence, forming a path easy to walk along.

“This we have to find out about,” Biff said. “Why fence in a mountain top unless there’s something inside that’s top secret?”

“That fence could be electrified. Stay clear of it,” Muscles warned.

“Could be,” Biff said, “but I doubt it. It would take a lot of power to do it. Besides, where would the power come from? Let’s follow it, to the right. But be alert. Good fences don’t mean good neighbors here. I’ve a hunch these good fences mean good guards every few feet.”
