"Yes; but these Martian boobies haven't your muscles. Aber Blitzen! did you see that fellow mount his bird again?"

I had seen it, and I do not remember anything more wonderful than this operation, which was repeated for each rider. The man went in front of his bird, turned his back, and stooped forward. The bird then curved his long neck to the ground, and put his head and neck between the legs of the rider, who clutched tightly with his arms and legs. With a swift, graceful swing, the bird lifted its head on high, carrying the rider as if he were nothing. When the great neck was again erect, the man slid carefully down it to his place, much as one might slip down a telegraph pole. Then two of the birds turned back to the city as swiftly as they could go, and the other two took separate side trails and soon disappeared.


CHAPTER III

The Armies of Mars

As the two returning birds passed the marching soldiers, their riders evidently delivered some message to the captains, for the soldiers suddenly broke forward in a run, using their long cross-bows with great dexterity as jumping staves. Placing the outer end upon the ground ahead of them as they ran, they leaped and hung upon the cross-piece with their hands. The springy resistance of this tough wood imparted to them a forward motion with its rebound, and they scaled great distances at each jump. The whole company did it in concert, and they made almost as great speed as if they had been riding bicycles. The slingers were consequently left far in the rear.

Less than half way up the incline the archers stopped, arranged their bow-thongs, and selected feathered arrows from a pouch slung over their shoulders.

"They can never hit us from that distance!" I exclaimed; "a rifle would not carry so far."

"You forget the weak gravity which will bend their course down very little, and the thin air which will barely resist their flight; this is a model planet for archery," he answered. "Quick! drop behind your shield! They have fired the first volley!"
