 Nomads of the North, A Story of Romance and Adventure under the Open Stars written by James Oliver Curwood. It was late in the month of March, at the dying-out of the Eagle Moon, that Neewa the black bear cub got his first real look at the world. Noozak, his mother, was an old bear, and like an old person she was filled with rheumatics and the desire to sleep late. So instead of taking a short and ordinary nap of three months this particular winter of little Neewa's birth she slept four, which, made Neewa, who was born while his mother was sound asleep, a little over two months old instead of six weeks when they came out of den.
