The guard departed, having first carefully tied the dynamiters with Henry's clothesline. Mary Hill sat down beside Henry, the big gun balanced on her knee. Her cold, small fingers crept into his palm. She was little and dear, she might have been the mother that he missed or the daughter he had never had. The old man patted her wrist gently and a slow ache swelled within him, made up of loneliness and weariness. Then a new thought comforted him. She'd be there every day--in that tower, in his garden, the green eye-shade binding down her rebellious hair. He gave a tremendous sigh and his age-old war against the B. & A. perished in lusty middle age. At this minute two-thirds of the village of Elsie surged into his garden. Henry shambled up, jerked his suspenders straight, hunted his hat. Men were crowding round him--he saw mouths moving excitedly, hands waving. They beat him on the back, they shook his hand. But Henry pulled away. "Lemme alone," he yelled at the curious who milled about him. "You lemme alone. I've gotta feed my cats!" GRAINS SEND ROOTS MANY FEET INTO EARTH Investigators for the Carnegie Institution of Washington have reported some interesting discoveries about the depth to which food plants send their roots. Trees and other perennials send tap-roots to a great distance into the earth, but that cereals, which start new from the seed each season, do the same, has not been generally understood. Professor John E. Weaver reports that in Nebraska wheat and oats were found to send roots down to a depth of from six to eight feet, while corn roots were found eight feet deep. New agricultural methods may result from these investigations. HELICOPTERS MAY MAKE AIRPLANES OBSOLETE
