Excerpt from The Life of Inland Waters: An Elementary d104 Book of Fresh-Water Biology for American StudentsThe study of water life, which is today the special province of the science of limnology*, had its beginning in the remote unchronicled past. Limnology is a modern name; but many limnological phenomena were known of old. The congregating of fishes upon their spawning beds, the emergence of swarms of May - ies from the rivers, the cloudlike ight of midges over the marshes, and even the water bloom spreading as a filmy mantle of green over the still surface of the lake such things could not escape the notice of the most casual observer. Two of the plagues of Egypt were limnological phenomena; the plague of frogs, and the plague of the rivers that were turned to blood.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
