Girls and mothers hurried into their coats and out into the frosty air. The street sloped down sharply, and the middle of the road was filled with flying bobsleds, as the young people of the neighborhood took advantage of the snowy crust. Sahwah brought out her brother's bob, which he was not using this evening, and piled the whole company on behind her. She could steer as well as a boy. Down the long street they shot, from one patch of light into another as they passed the lamp posts. The mothers shrieked with excitement and held on for dear life. "Oh," panted Mrs. Brewster when they came to a standstill at the bottom of the slope, "is there anything in the world half so exciting and delightful as coasting?" Down they went, again and again, laughing all the way, and causing many another bobload to look around and wonder who the jolly ladies were. Most of the mothers lost their breath in the swift rush and had to be helped up the hill to the starting point. Once Sahwah turned too short at the bottom of the street and upset the whole sledful into a deep pile of snow, from which they emerged looking like snowmen. "Oh-h-h," sputtered Mrs. Brewster, "the snow is all going down inside of my collar! Sarah Ann, you wretch, you deserve to have your face washed for that!" She picked up a great lump of snow and hurled it deftly at Sahwah's head. It struck its mark and flew all to pieces, much of it going down the back of her neck. "This coasting is all right," said Mrs. Gardiner, "but, oh, that walk up hill!" Mrs. Evans spied her machine standing in front of the Brewster house, and it gave her an idea. "Why not tie the bob to the machine," she said, "and go for a regular ride?" This suggestion was hailed with great joy, and carried out with alacrity. "Would you like to drive, mother?" asked Gladys. "No, indeed!" said her mother. "I'm out sleigh-riding to-night. You get in and drive it yourself!" Gladys complied, with Migwan up beside her for company, and away they flew up one street and down another and through the park. And just as they were going around a curve, Sahwah, who sat at the front end of the sled, untied the rope, and away went the machine around the corner, and left them stranded in the snow. Gladys felt the release of the trailer, but pretended that she knew nothing about it, and drove ahead at full speed, and traveling in a circle, came up behind the marooned voyagers and surprised them with a hearty laugh. This time she towed them back to Sahwah's house, where they drank hot cocoa to warm themselves up, and all declared they had never had such fun in their lives. "And to think how near I came to missing this!" said Mrs. Evans, as she and Gladys were driving home, and she shivered when she remembered how she had almost gone to the musicale. CHAPTER VI. GLADYS UPHOLDS THE FAMILY CREDIT.
