"It's the alkali that counteracts the poison," explained Han. "They say that if you can bathe the places in alcohol soon after you come in—in contact with the ivy—"

"For the love of Pete!" exclaimed Perry. "Forget about it, Han! You'll worry yourself to death over that poison-ivy. Maybe it didn't bite you, after all."

"Of course it did!" replied the other resentfully. "It always does. If I had some alcohol, though—"

"Well, come on and get some. We've got to find the boat first, haven't we?"

"Yes, but I don't think it's that way."

"Then you try the other way, and if you find it, sing out so I'll hear you."

"All right." They separated, each following the edge of the water, and presently Perry's voice rang out. "Here she is, Han!" he called. A faint hail answered him and Perry stowed the milk-can in the bow of the little boat and seated himself to wait. A few minutes later, as Han still tarried, he shouted again. This time there was no reply however, and Perry muttered impatiently and found a more comfortable position. When some five minutes more had passed he got to his feet and yelled at the top of his lungs. "Get a move on, Han! The milk's getting sour and I'm getting cold!" he shouted. An answering cry came from closer by, but what it was that Han said Perry couldn't make out. He turned his coat collar up, plunged hands in pockets and viewed the grey mist scowlingly. Then he began to listen for footsteps crunching the sand. But no sound save the lapping of water on the beach and the creaking of a boom on an unseen boat reached him.

"It would serve him right to leave him here," he muttered resentfully. "Anyway, I'm not going to yell at him any more. I suppose he's so taken up with his poison-ivy business that he can't think of anything else. Wonder if I got into that stuff, too!" The idea was distinctly unwelcome. He thought he recalled brushing through leaves as he crossed the wall. He had never had any experience with poison-ivy and didn't know whether or not he was susceptible, but it seemed to him that there was a distinct itching sensation on his back. He squirmed uncomfortably. Then a prickly feeling on his left wrist set him to rubbing it. He examined the skin and, sure enough, it was quite red! He had it, too! You had blisters all over you, Han had said. Perry looked for blisters but found none. Still, he reflected miserably, it was probably too early for them yet. He suddenly found himself rubbing his right wrist too. And that, also, was distinctly inflamed looking, although not so red as the other. Gee, he'd ought to do something! Alcohol! That was it! He ought to bathe the places in alcohol! He jumped out of the dingey, pushed it down the beach into the water and sprawled across the bow. Then he shoved further off with an oar and sudsided onto a seat.

"Back in ten minutes for you, Han!" he shouted. "You wait here! I'll bring some alcohol!"

When a dozen choppy strokes had taken him out of sight of the shore his panic subsided a little and two thoughts came to him. The first was that he was treating Han rather scurvilly and the second was that he hadn't more than the haziest notion where the Adventurer lay! But, having embarked, he kept on. Probably ten or fifteen minutes wouldn't make much difference in Han's case, while, as for finding the cruiser, he would shout after he had rowed a little further and doubtless someone aboard would hear him.
