"Dick," said Buttons, after a long pause, "you are as pale as a ghost. I believe you must be beginning to feel the miasma from these plains."

"Oh no," said Dick, dolefully; "something worse."

"What's the matter?"

"Do you remember the eggs we had for dinner last evening?"

"Yes."

"That's what's the matter," said Dick, with a groan. "I can't explain; but this, perhaps, will tell thee all I feel."

"_Gorgons, and hydras, and chimeras dire_."
