“I am surprised, sir,” boomed Challenger, stroking his majestic beard, “that any man of science should commit himself to so ignoble a sentiment.  You are in a land which offers such an inducement to the ambitious naturalist as none ever has since the world began, and you suggest leaving it before we have acquired more than the most superficial knowledge of it or of its contents.  I expected better things of you, Professor Summerlee.”

“You must remember,” said Summerlee, sourly, “that I have a large class in London who are at present at the mercy of an extremely inefficient locum tenens.  This makes my situation different from yours, Professor Challenger, since, so far as I know, you have never been entrusted with any responsible educational work.”

“Quite so,” said Challenger.  “I have felt it to be a sacrilege to divert a brain which is capable of the highest original research to any lesser object.  That is why I have sternly set my face against any proffered scholastic appointment.”

“For example?” asked Summerlee, with a sneer; but Lord John hastened to change the conversation.

“I must say,” said he, “that I think it would be a mighty poor thing to go back to London before I know a great deal more of this place than I do at present.”

“I could never dare to walk into the back office of my paper and face old McArdle,” said I. (You will excuse the frankness of this report, will you not, sir?) “He’d never forgive me for leaving such unexhausted copy behind me.  Besides, so far as I can see it is not worth discussing, since we can’t get down, even if we wanted.”

“Our young friend makes up for many obvious mental lacunae by some measure of primitive common sense,” remarked Challenger.  “The interests of his deplorable profession are immaterial to us; but, as he observes, we cannot get down in any case, so it is a waste of energy to discuss it.”

“It is a waste of energy to do anything else,” growled Summerlee from behind his pipe.  “Let me remind you that we came here upon a perfectly definite mission, entrusted to us at the meeting of the Zoological Institute in London.  That mission was to test the truth of Professor Challenger’s statements.  Those statements, as I am bound to admit, we are now in a position to endorse.  Our ostensible work is therefore done.  As to the detail which remains to be worked out upon this plateau, it is so enormous that only a large expedition, with a very special equipment, could hope to cope with it.  Should we attempt to do so ourselves, the only possible result must be that we shall never return with the important contribution to science which we have already gained.  Professor Challenger has devised means for getting us on to this plateau when it appeared to be inaccessible; I think that we should now call upon him to use the same ingenuity in getting us back to the world from which we came.”

I confess that as Summerlee stated his view it struck me as altogether reasonable.  Even Challenger was affected by the consideration that his enemies would never stand confuted if the confirmation of his statements should never reach those who had doubted them.
