An unfortunate quarrel between our pepper-pots marked the outset of our new stage. Challenger had from the moment of joining us issued directions to the whole party, much to the evident discontent of Summerlee. Now, upon his assigning some duty to his fellow-Professor (it was only the carrying of an aneroid barometer), the matter suddenly came to a head.

“May I ask, sir,” said Summerlee, with vicious calm, “in what capacity you take it upon yourself to issue these orders?”

Challenger glared and bristled.

“I do it, Professor Summerlee, as leader of this expedition.”

“I am compelled to tell you, sir, that I do not recognize you in that capacity.”

“Indeed!” Challenger bowed with unwieldy sarcasm. “Perhaps you would define my exact position.”
