THE HEAT-RAY
were with others in this attempt at communication. This little group had in its advance dragged inward, so to speak, the circumference of the now almost complete circle of people, and a number of dim black figures followed it at discreet distances.
Suddenly there was a flash of light, and a quantity of luminous greenish smoke came out of the pit in three distinct puffs, which drove up, one after the other, straight into the still air. This smoke (or flame, perhaps, would be the better word for it) was so bright that the deep blue sky overhead, and the hazy stretches of brown common towards Chertsey, set with black pine-trees, seemed to darken abruptly as these puffs arose, and to remain the darker after their dispersal. At the same time a faint hissing sound became audible.
Beyond the pit stood the little wedge of people, with the white flag at its apex, arrested by these phenomena, a little knot of small vertical black shapes upon the black ground. As the green smoke rose, their faces flashed out pallid green, and faded again as it vanished. Then slowly the hissing passed into a humming, into a long, loud, droning noise. Slowly a humped shape rose out of the pit, and the ghost of a beam of light seemed to flicker out from it.
