Plan and sections of self- maintaining-, self-filling trough. Desert model. This installation is placed in an excavation corresponding with out- side contours. The top of the struc- ture is level with the earth surface. Structure is to be made of rein- forced concrete (1 part cement, 5 parts gravel). An oiled earth catchment apron is to be built, draining into the small settling basin. Main tank is covered with either redwood planking or reinforced concrete. A shade and coyote guard is to be built over the sloping drinking trough. The small capacity of most of the quail watering troughs tried has necessitated several filling and inspection trips per season, while mechani- cal difficulties have been present in nearly all cases, making the use of , such tanks a positive hazard to any population of quail entirely dependent on them. In some instances the reservoir would not maintain its supply 1 Submitted for publication, June, 1943. (157).
