Shadows were photographed in a wire-model greenhouse oriented in N-S, E-W, and NE to SW (45°) directions in a heliodon which simulated 39° N latitude. Photographs were taken at 2 hr intervals during morning hours of winter and summer solstices. E-W greenhouses cast fewer shadows than other orientations during the winter solstice. Similar amounts of shadows occurred in all orientations during the summer solstice.
