Monadnock Guide, edited by Henry I. Baldwin. Concord, New Hampshire; Society for the Protection of New Hampshire Forests, 1970. 128 pages, 31 photos, line drawings, 3 maps. $2.00

An attractive, pocket-sized guide of the “biggest little mountain” of 3165 feet in southern New Hampshire. It covers the history of man’s connection with the mountain for over 200 years, and its natural history (geology, weather, vegetation, wild life, birds, small mammals, insects). Trails are described with a sketch map showing 82 points of interest and a topographical map and with advice for the many thousands of people whohike about 1700 feet to the summit every year. It is gratifying that so much of interest has been observed and written about this enticing little mountain as a labor of love.
