I did not need a manual of green Martian etiquette to know what reply to make, for, in fact, I was so wild with anger that I could scarcely refrain from drawing my pistol and shooting him down for the brute he was; but he stood waiting with drawn long-sword, and my only choice was to draw my own and meet him in fair fight with his choice of weapons or a lesser one.

This latter alternative is always permissible, therefore I could have used my short-sword, my dagger, my hatchet, or my fists had I wished, and been entirely within my rights, but I could not use firearms or a spear while he held only his long-sword.

I chose the same weapon he had drawn because I knew he prided himself upon his ability with it, and I wished, if I worsted him at all, to do it with his own weapon. The fight that followed was a long one and delayed the resumption of the march for an hour. The entire community surrounded us, leaving a clear space about one hundred feet in diameter for our battle.
