DONALD AND ED TYLER TRY THE GYMNASIUM.

Pretty soon, boys who came to jeer remained to try the horizontal bar, or the "horse," or the ladder that stretched invitingly overhead from one end of the building to the other. By special suggestion, Don's and Dorry's Christmas gifts from Uncle were a flying-course, a swinging-bar, and a spring-board. Jack and Don carted load after load of sawdust from the lumber-mill—to soften the deck in case of a slip from the rigging, as Jack explained to Lydia—and presto! the gymnasium was in full operation.

All of which explains why Josie Manning and Dorothy Reed bought dark-blue flannel, and sent to town for the latest pattern for gymnasium dresses; why Don and Ed soon exasperated them by comfortably purchasing suits ready made; why Dorry's cheeks grew rosier; why Uncle was pleased; why Jack was proud; and why Lydia was morally sure the D's would break their precious necks, if somebody didn't put a stop to it.
