discovered marked extreme astonishment, and the others were evidently satisfying themselves that I had not molested their young. They were conversing together in low tones, and gesticulating and pointing toward me. Their discovery that I had not harmed the little Martians, and that I was unarmed, must have caused them to look upon me with less ferocity; but, as I was to learn later, the thing which weighed most in my favor was my exhibition of hurdling. While the Martians are immense, their bones are very large and they are muscled only in proportion to the gravitation which they must overcome. The result is that they are infinitely less agile and less powerful, in proportion to their weight, than an Earth man, and I doubt that were one of them suddenly to be transported to Earth he could lift his own weight from the ground; in fact, I am convinced that he could not do so. My feat then was as marvelous upon Mars as it would have been upon Earth, and from desiring to annihilate me they suddenly looked upon me as a wonderful discovery to be captured and exhibited among their fellows. The respite my unexpected agility had given me permitted me to formulate plans for the immediate future and to note more closely the appearance of the warriors, for I could not disassociate these people in my mind from those other warriors who, only the day before, had been pursuing me. I noted that each was armed with several other weapons in addition to the huge spear which I have described. The weapon which caused me to decide against an attempt at escape by flight was what was evidently a rifle of some description, and which I felt, for some reason, they were peculiarly efficient in handling. These rifles were of a white metal stocked with wood, which I learned later was a very light and intensely hard growth much prized on Mars, and entirely unknown to us denizens of Earth. The metal of the barrel is an alloy composed principally of aluminum and steel which they have learned to temper to a hardness far exceeding that of the steel with which we are familiar. The weight of these rifles is comparatively little, and with the small caliber, explosive, radium projectiles which they use, and the great length of the barrel, they are deadly in the extreme and at ranges which would be unthinkable on Earth. The theoretic effective radius of this rifle is three hundred miles, but the best they can do in actual service when equipped with their wireless finders and sighters is but a
