In the third volume of the series, “Ruth Fielding at Snow Camp; Or, Lost in the Backwoods,” Ruth and some of her school friends spend a part of the mid-winter vacation at Mr. Cameron’s hunting lodge in the Big Woods, where they enjoy many winter sports and have adventures galore.

Ruth and Helen occupied a “duo” room on the second floor of the West Dormitory; but when Mercy Curtis, the lame girl, had come to Briarwood in the middle of the first term, the chums had taken her in with them, the occupants of that particular study being known thereafter among the girls of Briarwood as the Triumvirate.

Helen, when deserted by The Fox, who, from that first day at Briarwood Hall, had shown herself to be jealous of Ruth Fielding, for some reason, went slowly up to her room and found Ruth and Mercy there before her. There was likewise a stout, doll-faced, jolly girl with them, known to the other girls as “Heavy,” but rightly owning the name of Jennie Stone.

“Here she is now!” cried this latter, on Helen’s appearance. “‘The candidate will now advance and say her a-b-abs!’ You looked scared to death when they shot you with the lime-light. I was chewing a caramel when they initiated me, and I swallowed it whole, and pretty near choked, when the spot-light was turned on.”

Mercy, who was a very sharp girl indeed, was looking at Helen slily. She saw that something had occasioned their friend annoyance.

“What’s happened to you since we came from the supper, Helen?” she asked.

“Indigestion!” gasped Heavy. “I’ve some pepsin tablets in my room. Want one, Nell?”

“No. I am all right,” declared Helen.

“Well, we were just waiting for you to come in,” the stout girl said. “Maybe we’ll all be so busy to-morrow that we won’t have time to talk about it. So we must plan for the Lighthouse Point campaign now.”

“Oh!” said Helen, slowly. “So you can make up your party now?”
