CLEAN WATERS.
Th4i• best methods of prevention are very fully discussed iri the. 'Journal of the Royal Society for the Protection of Birds. The throwing out of oil is a gross waste as well as a cruel habit.' Apparatus' is available, and is not very costly, for separating the oil, and any shipmaster who pleases can do what every owner of a. sugar factory does : he can cleanse. the ejected Offal and prevent the fouling of the waters. The Germans, I believe; are partiOularly careful in such methods of separation. The United States are co-operating very heartily and are now " endeavouring to secure the signatures of all the Maritime Powers " to a convention prohibiting any ship from discharging oily waste within fifty miles of a shoe:. In some places the very floor of the sea is coated with black refuse that must destroy marine life. Definite research work is needed on the history of the oil after it has been released on the surface of the waters. Similar research is needed in regard to the motor oil on the roads, some of which finds its evil way to the trout streams.
