So please buy this book (£2.50 from the Essex Naturalists Trust or bookshops) and get to work improving the records in your area. If the price seems steep for a 152 page paperback, then remember that the profits (if any) help the Trust in its con- servation work. If you buy direct from the Trust then they get more profit (but you still pay the same). David Corke SLOW-WORM SURVEY May I thank all those who have kindly sent in reports of Slow-Worms. New records have been reported from Maldon, Brentwood and Chelmsford areas. Please inspect your compost heap for slow-worms as they climb up just under the surface where it is warm and dry and if the top is just raked off exposing the top of the firm com- post they can be seen to glide off as they are disturbed. Further records welcome please to: D. R. Scott, Court Hill, Little Leighs, Chelmsford. CM3 1PG.

The exception to this was in April this year when on hearing mice in a tea chest I investigated more closely. The animals had nested in old clothes chewed up in the tea chest, and they had carried in some thirty or forty full-sized acorns for their food. The nearest oak tree is thirty feet from the bungalow, and up a sheer brick wall would
