The story of the exposition; being the official history of the international celebration held at San Francisco in 1915 to commemorate the discovery of the Pacific Ocean and the construction of the Panama Canal. on the part of the manin charge. In the Exposition year such systems were being applied toapartment houses, hotels, and individual residences. An exhibit that everybody liked to watch at work was the gradingmachine of the Price Fruit Sizer of North Yakima, Washington. Insteadof passing fruit through holes of various sizes, this machine worked bymomentum, and so graded according to weight, tossing wooden apples by asort of minature catapult into canvas pockets at various distances. Inas-much as the impulse was uniform the lightest apples went the farthest; andthe precision of the machine, doing it over and over again with all sizes offruit, seemed miraculous. It dropped the same wooden ball into the samepocket every time, and the pockets were not large. They were of coursedevised in such shape as to prevent bruising, and the machine could tosseggs a dozen feet without breaking them. Twenty-six of these contrivanceswere sold to Watsonville packing houses before the Exposition was THE SPRING FLOWER SHOW
