The bubble had become a blooming horror sailing slowly westward above the storm-tossed Atlantic. And all the chemical agents which Lawton sprayed through the ventilation valves failed to impede the growth or destroy a single seed pod.

It was difficult to kill plant life with chemicals which were not harmful to man. Lawton took dangerous risks, increasing the unwholesomeness of their rapidly dwindling air supply by spraying out a thin diffusion of problematically poisonous acids.

It was no sale. The growths increased by leaps and bounds, as though determined to show their resentment of the measures taken against them by marshalling all their forces in a demoralizing plantkrieg.

Thwarted, desperate, Lawton played his last card. He sent five members of the crew, equipped with blow guns. They returned screaming. Lawton had to fortify himself with a double whiskey soda before he could face the look of reproach in their eyes long enough to get all of the prickles out of them.

From then on pandemonium reigned. Blue funk seized the petty officers while some of the crew ran amuck. One member of the engine watch attacked four of his companions with a wrench; another went into the ship's kitchen and slashed himself with a paring knife. The assistant engineer leapt through a 'chute opening, after avowing that he preferred impalement to suffocation.

He was impaled. It was horrible. Looking down Lawton could see his twisted body dangling on a crimson-stippled thornlike growth forty feet in height.

Slashaway was standing at his elbow in that Waterloo moment, his rough-hewn features twitching. "I can't stand it, sir. It's driving me squirrelly."

"I know, Slashaway. There's something worse than marijuana weed down there."

Slashaway swallowed hard. "That poor guy down there did the wise thing."

Lawton husked: "Stamp on that idea, Slashaway—kill it. We're stronger than he was. There isn't an ounce of weakness in us. We've got what it takes."
