Vol. 2(1) has made the most of this situation but it has done so intelligently by presenting a range of different viewpoints. Apart from the Editorial there are five papers by conservationists, planners, farmers and local authorities. Two of the most interesting, by Chris Hall, past Director of the Council for the Preservation of Rural England, and David Helland of the National Farmers' Union, represent opposing points of view but make telling points because their approaches are realistic and practical. When I read the first issue of Ecos a year ago, I thought it looked like becoming the Private Eye of the conservation movement. I am pleased to see that a year later, it has evolved into an impressive and objective publication and lost none of its independent approach, which I think is essential to a successful future. E.D.
Lakes of New York State. Volume III. Ecology of the Lakes of East-Central New York. Edited by Jay A. Bloomfield. Academic Press, New York, 1980. 416 pp. 23.5 x 15.5 cm. Price: $29.50.
This volume is the third in a series which profiles the geological, physical, chemical and biological properties of the major freshwater lakes in the State of New York. Volume I described the present ecological condition of the Finger Lakes in central New York, whilst Volume II covered four important lakes in western New York. The latest, Volume III, deals with three lakes in areas of extensive agriculture in eastern New York, all of them about the same surface area. Two of these, Saratoga and Canadarago Lakes, are very productive biologically--mainly due to cultural eutrophication. The third, Otesego Lake, is much deeper than the others and relatively less affected by man's activities. Following the introductory matter, the main body of the book is taken up by three separate, but parallel, accounts of these lakes, each occupying about one third of the volume. Each account is individually referenced, but there is a single index to the book as a whole. This volume maintains the high standard set by its two predecessors and will be of interest to anyone concerned with north temperate lakes and eutrophication, pollution and other factors changing their nature. Eleven authors are involved altogether and their accounts have been well edited and integrated by Jay A. Bloomfield. Having just edited and seen off to the press a comparable book on the ecology of Scotland's largest lochs, the reviewer is well aware of the many problems involved in producing a well-balanced multi-author account of this kind. Those concerned with this one have been successful and the series sets a high standard for limnologists and publishers in other parts of the world to follow. PETER S. MAITLAND
