"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.
"The problem of the descent is at first sight a formidable one," said he, "and yet I cannot doubt that the intellect can solve it. I am prepared to
