Since no man can possibly be familiar with the facts of all these branches of knowledge, it is almost certain that occasional errors will have crept in; but there has been very earnest effort to verify so far as possible every statement of fact, and thus reduce such errors to a minimum.

It is certain that the specialist in any of the fields covered will be dissatisfied with the treatment of that field; but in order to cover the entire subject of conservation in a book of moderate size it is necessary to abbreviate; not only so, but to omit many ramifications of the subject which it would be interesting and profitable to follow. Doubtless, in the near future, there will be separate books on conservation for each of the divisions of the subject; and in such books there will
