15. tin cans, plastic sheeting ...'. Obviously the toxic waste does not worry the badgers too much. So far as sett numbers are concerned, we have so far found about 350 in Essex, and the likely total is perhaps 500 or so. Assuming 3/5 active at any one time and four animals, say, per sett, this would give a total population for the county of 1200 animals. I am firmly of the opinion that they are declining in number generally, but we need much more information to be sure. Bob Cowlin, Essex Badger Recorder ---oOo--- BOOK REVIEWS - BOTANY AND DEER One of the perks of editing the Essex Naturalist is that some kind publishers send me free copies of their books. We don't print reviews in the Essex Naturalist any more - hence this section in the Bulletin. "Bellamy on Botany" has reached its second edition - published a few months ago to coincide with the re-run of the BBC-tv series. The book is useful even if you did not see the series (and if you missed it, watch out for a repeat in a year or two). If you find Bellamy's enthusiastic approach to botany infectious, then you will be pleased to know that this book is written in just the same style as his TV talks. Each chapter takes a separate theme - grass, wood structure, fungi and bogs for example. The level is best suited to naturalists who have a general interest in botany - a good section on follow-up studies tells you how to become a more knowledgeable botanist if the bug bites you. Thirty bob for a thinnish paperback with a fair number of black and white photographs seems fair (but not good) value.
