Estate Econofnics. By Andrew Slater. London : Constable 

 and Co., Ltd., 191 7, pp. xiii + 264. Many illustrations. 



The above book is planned and written as a guide to land- 

 owners, land agents, factors, foresters, and others. The subject 

 matter is dealt with in a short and concise manner.

 drainage, embanking of rivers, construction and maintenance of 

 roads, fencing, gates, etc., will be found of equal interest and

 executed drawings, prepared by Mr Andrew Slater, jun. An 

 appendix, containing legal and other notes, is given and forms 

 a very useful addition to a work of this kind. One or two
