I reached the head of the trail in plenty of time and hurried down after Llana and Pan Dan Chee, whom I found waiting for me when I caught up with them.

As we descended, I looked up and saw the green warriors at the edge of the rift looking at us; and, guessing what would happen, I dragged Llana into the shelter of an overhanging ledge. Pan Dan Chee followed just as radium bullets commenced to explode close to us.

The rifles with which the green men of Mars are armed are of a white metal, stocked with wood; 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 projectiles which they use explode when they strike an object, for they have an opaque outer coating which is broken by the impact, exposing a glass cylinder, almost solid, in the forward end of which is a minute particle of radium powder.

(Editor's Note) I have used the word radium in describing this powder because in the light of recent discoveries on earth I believe it to be a mixture of which radium is the base. In Captain Carter's manuscripts it is mentioned always by the name used in the written language of Helium and is spelled in hieroglyphics which it would be difficult and useless to reproduce.

The moment the sunlight, even though diffused, strikes this powder it explodes with a violence which nothing can withstand. In night battles one notices the absence of these explosions, while the following morning will be filled at sunrise with the sharp detonations of exploding missiles fired the preceding night. As a rule, however, non-exploding projectiles are used after dark.

I felt it safer to remain where we were rather than to expose ourselves by attempting to descend, as I doubted very much that the huge green warriors would follow us down that steep declivity on foot, for the trail was too narrow for their great bodies and they hate going anywhere on foot.

After a few minutes I investigated and found that they apparently had departed.

Then we started on down into the valley, not wishing to risk another encounter with that great horde of cruel and ruthless creatures.

Chapter 3

The trail was steep and oftentimes dangerous for it zig-zagged down the face of an almost perpendicular cliff. Occasionally on a ledge we would have to step over the skeleton of a man, and we passed three newly dead bodies in various stages of decomposition.
