such friends, was a matter of surprise to all their acquaintances. But those who have read of the young ladies in the previous stories of the series, “Dorothy Dale;—A Girl of To-Day,” and “Dorothy Dale at Glenwood School,” have had sufficient introduction to these interesting characters to understand how natural it was for a lily (our friend Dorothy) to love and encourage a frolicsome wild flower (Tavia) to cling to the cultured stalk, to keep close to the saving influence of the lily’s heart—so close that no gardener would dare to tear away that wild flower from the lily’s clasp, without running the risk of cruelly injuring the more tender plant.

Then the girls settled down to wait. The Fire Bird, was a touring car in which the girls had enjoyed some noted rides about their home town
