e was pointing to a flat bodied fish with incredible jaws that lay on the grass, emitting strange sounds even in the air. It flapped about madly. Its jaws closed upon a stick nearly half an inch thick, and cut it through.

"It is a piranha," said Paula. "The same fish that bit your hand. It can bite through a copper wire fastened to a hook, but this hook is so long...."

"Pleasant," said Bell. Something large and red passed before his eyes. He struck at it instinctively.

"Don't!" said Paula sharply.

"Why?"

"It's a maribundi wasp," she told him "And its sting.... Children have died of it. A strong man will be ill for days from one single sting."

"Still more pleasant," said Bell. "The jungle is a charming place, isn't it?" He wiped the sweat off his face. "Any more little pets about?"

She looked about seriously.

"There." She pointed to a sapling not far distant. "The palo santo yonder has a hollow trunk, and in it there are usually ants, which are called fire-ants. They bite horribly. It feels like a drop of molten metal on your flesh. And it festers afterwards. And there is a fly, the berni fly, which lays its eggs in living flesh. The maggot eats its way within. I do not know much about the jungle, but my father has—had a fazenda in Matto Grosso and I was there as a child. The camaradas told me much about the jungle, then."

Bell winced, and sat down beside her. She had Ribiera's pearl handled automatic within easy reach. She saw him looking at it.
