With a joyous cry the Earthmen started for the narrow mouth of the valley, all without guns. Gone was the helpless feeling of before; now they could fight too. Axes, spades, pitchforks, sticks and stones even, were their weapons. Hilary thrust his automatic into Joan's hand. "You use it, dear. I won't need it. Come on, Grim." Morgan smiled slowly, handed over his dynol pistol without a word to a weaponless man and stalked after his leader. His great hand clutched and unclutched unconsciously. This was what he wanted, hand-to-hand fighting. * * * * * By the time they reached the foot of the valley, the noise of the oncoming Mercutians sounded like the rumbling of thunder. Secure in their numbers there was no thought of concealment. The Earthmen were pitifully few, only thirty of them, and wretchedly armed. Hilary disposed of them up the slope of the hill on either side, set them to loosening jutting boulders. He was in command on one slope. Grim on the other. In a minute the Mercutians would be upon them. A simultaneous attack, no doubt; the fliers dropping low to loose their deadly rays from above as the land force attacked with their hardly less deadly hand rays. Hilary shot a last hasty glance aloft. His heart gave a great bound. The thin insubstantial vapors of a little before had solidified, taken on a grosser leaden hue. The sky was a sullen gray, shot through intermittently with the broad flares of a sun valiantly struggling to reassert its long undisputed sway. Little flickers of lightning played around the ragged edges of the clouds. To the most unobservant it was evident now that a storm was in the making. But might it not be too late? The sun still shone, and as long as its light pierced through, the weapons of the Mercutians held all their deadly potency. The alien invaders sensed the urgent necessity for quick action, for the fliers were dropping now, hundreds of them, to within range. Hilary heard the shouted orders of the Mercutians Cors, the crashing forward of a mighty host, and then the front of the attack burst out of the trees in an engulfing flood of gigantic unwieldy bodies and gray warty faces. A quick view of the stout ungainly Viceroy, Artok, another of the coldly saturnine visage of Urga in the front rank, and with a roar of gutturals, the attack was on. * * * * * Down from above came a myriad blinding flashes, turning the inclosed valley into an inferno of heat and rocking, boiling, shattered ground. Up the valley shot the massed hand rays of the hundreds as they swept along in close-packed trot.
