hills and
came upon the dead city beyond. We had passed within its streets and
were walking toward the central portion, when at an intersecting avenue
we saw a body of green warriors approaching.

"Tars Tarkas was in advance, and they saw him, but me they did not see.
The Thark sprang back to my side and forced me into an adjacent
doorway, where he told me to remain in hiding until I could escape,
making my way to Helium if possible.

"'There will be no escape for me now,' he said, 'for these be the
Warhoon of the South. When they have seen my metal it will be to the
death.'

"Then he stepped out to meet them. Ah, my Prince, such fighting! For

where he had stood; but at last they overwhelmed him, those behind
pushing the foremost upon him until there remained no space to swing

would invite disaster. I shall go alone. If I need your help, I will
return for you."

They did not like it, but both were good soldiers, and it had been
agreed that I should command. The sun already was low, so that I did
not have long to wait before the sudden darkness of Barsoom engulfed us.

With a parting word of instructions to Carthoris and Xodar, in case I
should not return, I bade them all farewell and set forth at a rapid
dogtrot toward the city.

As I emerged from the hills the nearer moon was winging its wild flight
through the heavens, its bright beams turning to burnished silver the
barbaric splendour of the ancient metropolis. The city had been built
upon the gently rolling foothills that in the dim and distant past had
sloped down to meet the sea. It was due to this fact that I had no
difficulty in entering the streets unobserved.

The green hordes that use these deserted cities seldom occupy more than
a few squares about the central plaza, and as they come and go always
across the dead se
