Abstract
THE beauty and purity of our rivers is a national heritage, and the increasing attention that is being turned towards problems of pollution is therefore welcome. But before the causes and effects of pollution can be truly understood it is necessary to have, as a foundation, a knowledge of the natural, unpolluted state. One of the most important. British contributions in this respect is to be found in a recent publication of the Water Pollution Board of the Department of Scientific and Industrial Research*. This report is concerned with the non-tidal reaches * of the River Tees and supplements the work on the tidal region previously published. The survey was undertaken by the Ministry of Agriculture and Fisheries, the research staff being under the direction of Dr. E. S. Russell. The report is drafted by Dr. R. W. Butcher, Dr. J. Longwell and Mr. F. T. K. Pentelow, who were botanist, chemist and zoologist, respectively, on the survey.
