My captor, whose name was Tars Tarkas, was virtually the vice-chieftain of the community, and a man of great ability as a statesman and warrior. He evidently explained briefly the incidents connected with his expedition, including my capture, and when he had concluded the chieftain addressed me at some length.

I replied in our good old English tongue merely to convince him that neither of us could understand the other; but I noticed that when I smiled slightly on concluding, he did likewise. This fact, and the similar occurrence during my first talk with Tars Tarkas, convinced me that we had at least something in common; the ability to smile, therefore to laugh; denoting a sense of humor. But I was to learn that the Martian smile is merely perfunctory, and that the Martian laugh is a thing to cause strong men to blanch in horror.
