moment, then withdrew it. Another inch was gone.

Micheals frowned, and pushed his glasses tighter against his nose. He held the spade against the rock with one hand, the other held close to the surface. More of the spade disappeared.

"Doesn't seem to be generating heat," he said to Conners. "Did you notice any the first time?"

Conners shook his head.

Micheals picked up a clod of dirt and tossed it on the object. The dirt dissolved quickly, leaving no trace on the gray-black surface. A large stone followed the dirt, and disappeared in the same way.

"Isn't that just about the damnedest thing you ever saw, Professor?" Conners asked.

"Yes," Micheals agreed, standing up again. "It just about is."

He hefted the spade and brought it down smartly on the object. When it hit, he almost dropped the spade. He had been gripping the handle rigidly, braced for a recoil. But the spade struck that unyielding surface and stayed. There was no perceptible give, but absolutely no recoil.

"Whatcha think it is?" Conners asked.

"It's no stone," Micheals said. He stepped back. "A leech drinks blood. This thing seems to be drinking dirt. And spades." He struck it a few more times, experimentally. The two men looked at each other. On the road, half a dozen Army trucks rolled past.

"I'm going to phone the college and ask a physics man about it," Micheals said. "Or a biologist. I'd like to get rid of that thing before it spoils my lawn."

They walked back to the house.

Everything fed the leech. The wind added its modicum of kinetic energy, ruffling across the gray-black surface. Rain fell, and the force of each individual drop added to its store. The water was sucked in by the all-absorbing surface.

Everything

The sunlight above it was absorbed, and converted into mass for its body. Beneath it, the soil was consumed, dirt, stones and branches broken down by the leech's complex cells and changed into energy. Energy was converted back into mass, and the leech grew.

Slowly, the first flickers of consciousness began to return. Its first realization was of the
