A Year in the Maine Woods

by Bernd Heinrich. AddisonWesley /William Patrick, 259 pages, $22.00.
Mr. Heinrich is a professor of zoology at the University of Vermont and the author of Ravens in Winter. His latest book is an account of a full year in a cabin among trees, birds, insects, and animals, all of which he observed with endless enthusiasm. The charm of Mr. Heinrich’s writing lies partly in his ability to describe weather and wildlife and partly in the curiosity that impels him to discover that red squirrels harvest maple syrup. The book is also a window on the past for anyone interested in such matters as how much wood is required to heat an ill-caulked cabin and how to conserve water by putting the well a long way from the house.
