Quote:
"The animals, all owned by Miss Shipman, are the only North American wild beasts trained to appear in motion pictures and include deer, elk, bear, cougar, wild cats, lynxes, wolves, coyotes, skunks, raccoons, weasels, chipmunks, mink, marmots, badgers and many other species. It is a remarkable collection when it is borne in mind that all the animals have appeared before the camera. Neither concealed wires nor leashes were used to restrain them when they 'acted' in The Grub-Stake. Kind words were the only persuasion."
