Accompanies Peary's Expedition.Miss Mamie Babb of Westbrook, Me., who sails with Commander and Mrs. Peary in 1he Roosevelt when the explorer makes his quest for the north pole, is perhaps the youngest woman who has ever undertaken such an expedition, She is 20 years old. It is not through the spirit of adventure*that she takes this trip, hut because she has been offered a large salary to go as steographer to the commander and companion to Mrs. Peary. Physically Miss Babb is a slight girl and does not look able to stanu great hardship. She is now staying at Eagle Ledge, an isolated island in Casco bay, the Peary summer home.
