The investigation will be continued through laboratory experiments on trapped normal ducks. It is hoped that the results will either prove or disprove certain phases of the duck disease. The progress of this work is greatly retarded because it is very difficult to duplicate natural conditions at the laboratory. Hence, any results that may be obtained by laboratory experiments will have to be repeated under natural field conditions as soon as the disease reappears in California. It is needless to emphasize that the conservation of the waterfowl is markedly afi'ected by the duck disease. At the present time relatively few suitable nesting and loafing areas absolutely free from the malady can be found in California. More water areas are being taken away from the birds each year by agricultural and industrial enterprises. A committee on game refuges has been appointed to correct, if possible, such conditions as exist in order to assure a safe and suitable refuge for waterfowl. However, little progress can be made until the origin and nature of the duck disease has been Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
