STABILITY This book obviously supplies a wide-felt need: it was first published in 1970, reprinted in 1972, 1975 and 1976. From the 89 pp. in the first edition it grew to 128 pp. in the second edition. It is richly illustrated with 32 colour plates of soils (same as in the first edition), 14 photographs and some 70 drawings (15 new ones): diagrammatic profile sketches, representations and sections, maps, block diagrams, schemes, toposequences of soils in different landscapes, a chronosequence illustrating the gilgai phenomena, etc. In the text there are some 35 profile descriptions and 22 tables, there is an index with about 600 entries (some 450 in the first edition), The list 'for further reading' contains about 100 references, twice as much as in the first edition, There has been some rearrangement of the subject matter, the chapter Soil Classification is rewritten and updated with the FAO/Unesco list of soil units (1974), the system of England and Wales and the French system (1967). On many places there are small additions and changes in the text. The book is certainly well-suited 'for students beginning an advanced study of

Stability of Tidal Inlets is a successor to two other books on tidal inlets authored or co-authored by Par Bruun. Two co-authors contributed 'Combinations of Waves and Currents'. In addition, James Purpura provided an appendix entitled 'Performance of a Jetty-weir Inlet Improvement Plan'. Bruun and the co-authors have produced a com, pendium of material concerning tidal inlet geomorphology, hydraulics, sedimentation and the design of inlet improvements. This book is the best available single source of information about tidal inlets and coastal engineering problems encountered in their vicinity. For those scientists and engineers in,,~lved with inlet problems, it will be a hcndy reference book. The first two chapters of the book provide a descriptive discussion of the origin and configuration of inlets and the reasons why inlets shoal and migrate. The third chapter considers inlet hydraulics including
