manipulated the space-lock. As the Zonals saw him disappearing they came in fast. Quade got another javelin from his belt and used it efficiently. But after that he was reduced to using his fists, which was not too effective under water. The Zonals began dragging him out of the lock. Quade reached out, caught a lever, and tried to anchor himself. He couldn’t. But inside the ship there were weapons. He struck out frantically at another lever. The inside port opened. The sealed ship became unsealed in an instant, and the lake poured in, carrying with it Quade and a dozen Zonals. By the time the water had settled, a steady stream of amphibians were swimming down through the open lock, and the water had changed color to streaky yellow and pink that gradually merged into an ambiguous darker hue. Briefly puzzled, Quade noticed that two carboys of the concentrated aqueous dye had been smashed. Also, Kathleen had left the ship’s lights on, so the Zonals, temporarily distracted, were able to see Quade and to converge on him. They got him down, clawing at his suit with their talons. That didn’t worry him. The armor was tough. But one of the Zonals, after breaking a tooth on Quade’s helmet, got a bright idea. He found a metal bar somewhere and began smashing it down on Quade’s head. He used it like a piston, so that water pressure was minimized, and the helmet began to show a webwork of fine cracks. Quade twisted, got hold of the bar and tussled it free. He levered oxygen into his suit hurriedly. Buoyancy took over, and he shot up out of the heap of Zonals and bounced off the ceiling. But the amphibians instantly swam up after him. It was then that Quade noticed the row of carboys in their wall-cradles beneath him.... He broke them. Using the metal bar, he floundered and fought and smashed his way through the Zonals down the line, while blue and green and translucent orange flowed out from the carboys, staining the water brilliantly. It was tremendously concentrated, this aqueous dye. And, while each dye had been made to blend transparently with water, there is a simple principle of the color-wheel that added up to complete opacity. If you mix a lot of colors, you get black. This wasn’t dead black, but it was darker and thicker than a Venusian fog on Darkside. Within moments the Zonals were fighting by touch
