"But let's hurry now, Ruth," he went on hastily to cover their mutual confusion. "Follow close in my steps and don't keep more than two or three feet behind me at any time."

They set off on the unknown path whose end meant to them either deliverance or death. The chances were against them, but their hearts were high and their courage steadfast.

They had need of all their fortitude, for they had not advanced forty paces before danger menaced them.

Drew holding his torch high so as to throw its light as far ahead as possible, stepped on what seemed to be a crooked stick in the path. Instantly the stick sprang to life, and a powerful, slimy coil wound itself around the man's leg as high as the knee.

His first impulse was to spring back. His next was to grind down with crushing force on the squirming thing beneath his heel. The second impulse conquered the first and he stood like a statue while a cold sweat broke out all over his body.

For he had realized by the feel that it was the reptile's head that was beneath his heel and must be kept there at all costs until the life was crushed out of it.

Gradually the writhings grew feebler, until at last the coils relaxed and fell in a heap about his foot.

"What is it Allen?" asked Ruth in alarm at his sudden stop and rigid pose. "Do you see anything?"

"There's no danger," he assured her, though his voice was not quite steady. "I must have stepped on a lizard or something like that, and it gave me a start."

He kicked the mangled reptile out of the path, but not before Ruth's horrified glance had seen that it was no lizard but something far more deadly.
