PREFACE
The Syndics of the Cambridge University Press propose to issue a Nature Study Series of which this is the first volume.
We count ourselves fortunate in securing Dr E. J. Russell as author and Soil as subject. The subject is fundamental, for, just as the soil lies beneath the plant and animal life we see, so is a knowledge of the soil necessary for all understanding of flora and fauna. The real complexity of the apparently simple element "Earth," and the variety of methods required for exploring it, are typical of the problems which the tout ensemble of the outdoor world presents to the naturalist.
