Excerpt from Aquatic Plants in Pond CultureIt is perhaps superuous to add that submerged plants bind the bottom soil together, thus acting as a deterrent to turbidity from that source, and that plants doubtless facilitate clarification when the water of a pond has become turbid with surface drainage after a rain or from other external causes of a temporary character. The superintendent of the Tupelo, Mississippi, station, Mr. C. W. Burn ham, cites as an evidence of this the numerous reservoirs or tanks in the West which are devoid of vegetation and in which the water is constantly roiled. It is possible that in some instances the absence of vegetation is due to the constantly roily water, a condition else where referred to, but control tests in aquaria demonstrate that in an aquarium containing Cabomba the water is clarified much more quickly than in one devoid of vegetation. It is believed that if many of the so-called tanks of the Western States now devoid of vege tation could be stocked with water plants, these would not only pre vent turbid water by binding the bottom soil together, but would under certain conditions prove an aid to clarification.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
