"Poison ivy!" Kitty sprang back as if the vine were about to sting her. "I never saw any before,—and I wanted to surprise Blue Bonnet—it looked so pretty. Oh, Alec, are you sure?"

"Sure?—positive. Dr. Judson pointed out lots of it around Camp, and we learned to give it a wide berth. But say, every one isn't susceptible, Kitty. Maybe you're immune."

"Oh, dear!" wailed Kitty. "What shall I do? Can't I be vaccinated or something to ward it off?"

"What's the trouble?" asked Uncle Joe, coming up in time to hear Kitty's despairing cry.

"Poison ivy," said Alec, pointing to the vines.

"Now that's bad." Uncle Joe kicked the innocent looking heap of greens off to one side. "I'll send up one of the boys to rake that up and get rid of it. Nasty stuff to have around,—'specially for folks with your—coloring." He eyed Kitty's milk-white freckled face apprehensively.

"If I get it and have to miss the party I'll never get over it!" Kitty declared.

"Oh, yes, you will—it only lasts a few days, generally," said Uncle Joe.

Kitty dabbed her eyes with her handkerchief.

"Here—don't do that!" Alec exclaimed hastily. "That might play the mischief with your eyes. Go bathe your face and hands with witch hazel, that may help. And hurry out again, Kitty—your friend Sandy is on the side veranda."
