"That's it," said Lord John. "The odds are that this plateau is of no great size, and we shall travel round it until we either find an easy way up it, or come back to the point from which we started."
"I have already explained to our young friend here," said Challenger (he has a way of alluding to me as if I were a school child ten years old), "that it is quite impossible that there should be an easy way up anywhere, for the simple reason that if there were the summit would not be isolated, and those conditions would not obtain which have effected so singular an interference with the general laws of survival. Yet I admit that there may very well be places where an expert human climber may reach the summit, and yet a cumbrous and heavy animal be unable to descend. It is certain that there is a point where an ascent is possible."
"How do you know that, sir?" asked Summerlee, sharply.
"Because my predecessor, the American Maple White, actually made such an ascent. How otherwise could he have seen the monster which he sketched in his notebook?"
"There you reason somewhat ahead of the proved facts," said the stubborn Summerlee. "I admit
