With Paul stooping low to keep from bumping his head, they half walked, half crawled along the passageway. The floor and walls had been smoothed, and evenly spaced beams supported the ceiling. Francesca extinguished the light because of the smoke in the tight confines, and they traveled in darkness. After about fifty feet the tunnel angled into another, slightly bigger passageway.

“This is the water works,” Francesca said in hushed tones. “We must be silent. The tunnel is only a couple of feet below ground, and the Chulo have sharp ears.”

Using a primitive fire starter similar to the one carried by Tessa's half-brother, Francesca got the lamp going again and they forged ahead. They made slow progress, but after about fifteen minutes the tunnel came to an end. Francesca motioned for Paul to squeeze up beside her. She pulled a small spade from her bag and chopped away at the blank dirt wall until the blade hit something with a thud.

“I'll need your strength again, Dr. Paul. Push against this hatch. I don't think anyone is at the river, but be cautious.”

She backed off to give Paul more room. He put his shoulder against the wood, braced himself, and shoved, gradually increasing the pressure until he felt the wood give. He pushed harder. The circular cover opened a few inches. Paul peered through the narrow space with one eye and saw water. With a final shove he popped the hatch off.

The opening was in the side of a grassy embankment. He slithered through the hole, then helped the others climb out. Moving from the cool, dark tunnel into the hot sunlight was a shock, and they blinked their eyes like moles. Paul replaced the hatch. While the others covered the opening he slid on his stomach to the top of the bank and peered over the edge.

The stockade fence and its grim decorations were a short distance away. The tunnel had passed right under it. A tall, billowing plume of black smoke rose from beyond the fence. What sounded like a flock of wild birds could be heard. As he listened the bird cries became human voices. He slid back down.

“It looks like they're having a weenie roast,” he announced with a grin. Turning to Francesca, he added, “Don't ever tell me you don't have a talent for arson.”

Francesca responded by motioning for the others to follow her along the edge of the river. They stayed low, hidden by the embankment, and after a few minutes came upon a dozen dugout canoes. They hauled two dugouts aside. Trout thought of scuttling the others, but their hulls were thick and not easily damaged.

“Anybody got a power saw?” he said. “Even a hatchet would do.”

Francesca reached into her sack and came out with a covered pot. Using a flat stone from the riverbed, she smeared the blackish yellow contents of the pot onto the other canoes. She lit the substance on fire. The wood flared into smoldering flames where she had daubed the unctuous mess.
