buoyant belts which all of us were wearing so that they floated away on the surface. But we had done some damage. Two or three of the big Tollgamo vessels seemed to be in distress. The one leading the line had checked its advance. Those behind seemed trying to hasten forward, so that now the ships were bunching. One of them, seemingly out of control, had slued sidewise, close to the edge of the abyss where the green-black depths went down perhaps a thousand fathoms. Perilously close, so that now as we stared it sagged drunkenly on the brink and seemed out of commission. And at the window portes of another of them, a dull-red glare was apparent. An interior fire. "Not too bad," Leh was muttering. "We'll do better, next time." Where was Nereid? My heart seemed to stick in my throat with apprehension as I watched the girls coming up. And then I saw her; still unharmed. She came close past our turret on her power-sled, her white arm waved at us as she flipped past and broke the surface for air. And then Allen suddenly gasped, "What the devil is that? What now?" Tollgamo wasn't waiting for our second dive! His leading ship suddenly was starting ahead of the others. And then suddenly, from three or four of the enemy vessels tiny black dots were rising. Water bullets.... Needle-like, foot-long projectiles. They came hurtling at us. And then they burst with muffled, blurred sounds of little explosions. Some were near the surface, tossing up spouts of iridescent water. It startled us into sudden confusion. Several of our girls were caught in the exploding puffs; and one of our cylinders. I saw it break apart in sluggish tearing fragments of metal and what had been its living occupants. A girl, caught at the surface, was hurled into the air. A chaos. And in the midst of it, Peters gave the signal for a general attack; sustained attack, this time. Again Leh plunged us into what now was a watery inferno. How long it lasted I cannot say. Ten minutes. Half an hour. An eternity of horror, with everyone for himself. There were times when I could see little of it. The shallow, fifty foot depth of ocean here was a glare of red and orange and opalescent light through which our cylinders dove and the girls plunged up and down like voracious little fishes. There was an inferno of lights and muffled ghastly
