Mr. Paul Rainey has stated that his wonderful animal pictures, which showed his happenings from the unloading of his expedition from an Atlantic steamer on the coast of Africa, through the various hunts, and up to his departure, likewise cost fifty thousand dollars. Some of these wonderful films demonstrated how practical was his much-laughed-at theory that the Mississippi hounds used for hunting bear could successfully hunt the destructive African lion and the chetah. These pictures, which were taken with the idea of permitting Mr. Rainey’s friends at home to journey with him in spirit in his travels, were first shown publicly last winter at the National Geographic Society in Washington to illustrate a lecture by Mr. Rainey. Those who then enjoyed them can feel only satisfaction to know that they have now been placed on public exhibition, to show to the people at large what Professor Henry Fairfield Osborn, President of the American Museum of Natural History, has declared to be “the greatest contribution to natural history of the last decade.” The writer recently saw these pictures, and while the films are naturally not as perfect as when first shown in Washington, all the essentials are faithfully reproduced. It is only recently that the streaky, flickering, eye-straining series of pictures first brought out have been supplanted by pictures so improved and so steady and continuous that the setting of a room or a landscape made up of hundreds of pictures appears as a single photograph. This is admirably illustrated by a portion of Mr. Rainey’s pictures, which show, through the peculiarly clear African atmosphere, a range of mountains ninety miles away. Again, his picture of the drinking-place, where, owing to a long drought, some of the animals had come eighty miles to scratch in the sand for water, shows the stillness of an immense landscape broken only by the swaying of the nests of half a hundred weaver-birds in a single tree, and by the scamper of monkeys, baboons, and other small animals two hundred and fifty yards from the camera. The same still background is shown as these little animals cautiously approach, drink, and are driven away by those of larger size, who in turn give way to companies of zebras, giraffes, rhinos, and elephants. In a recent lecture given to benefit a fund to establish an animal hospital in New York, Dr. Joseph K. Dixon is credited with having shown a rare set of films which took his audience on a most interesting trip through the Yellowstone Park, and showed them an animal hospital which nature had provided in a secluded spot of aspen-trees, where injured creatures went for rest and convalescence. Many vivid pictures showed lame deer, wounded elk, and bears having their cuts and bruises healed by their own applications of oil taken from the trees.
