Burton Holmes has received word from his operator, Mr. De Pue, who is now in Yellowstone Park with his chronomatographe and apparatus photographing the geysers in action, that he has visited the Dalrymple Farms, the largest farms in the world, and obtained several pictures of the thrashers and reapers in action. This will no doubt prove especially interesting, as these machines play such an important part in tossing wheat and its price into the air. This will be the first time that geysers have been thrown upon the screen by this new branch of photography, and their beauty will be enhanced by being seen in full play.
