It is a cold winter and everybody is sick. Frog arrives and tells them how long ago, the animals called the Great Spirit to meet with them. They complain that humans have all of the advantages, including hands, the ability to walk upright, master fire and create shelter, while they suffer each winter; the bears sniffling in dark caves, the bugs aching joints, the snakes soar bellies and the birds aching throats. The Great Spirit decides that during the winter the people will suffer like the bear and the snake and the insect and will be silenced as the birds, but Frog counsels him, and he decrees that the people may find a cure for these ills in the roots, the leaves and the bark of the plants if the people are smart enough to find them, and wise enough to remember them. - from Amzon
