concerning the sensibility of bees to color. The importance of "longness" or "rich-
ness" of outline is discussed. This chapter also reviews the famous discovery of
Von Frisch relating navigation by polarized light from the sky to the bee dances by
which the hive is notified of the success of a honey seeker. (Among other things,
bees cannot describe height in their dance.)

The mass movements of populations are discussed in Chapter V, entitled At the
Mercy of the Elements.


Tlio (lifTci-fiic(> in individual navijration as ojjposod to mass niijii'af inn is cinplia-
sizod. Locusts movin*; at the nicroy of the wind aro disfusscd. linllcrfly niij;ralions
are well treated. This chapter includes a discussion of the cffccl of pressure of air
or water on the sides of an orsanism in guiding animals.

The Migraiiou of Birds, Chapter VI. contains a good lex iew of many of the
observations and si^eculations that have been made concerning long distance travel
of birds. The fantastic long journeys of the bristle-thighed curlew and of the great
shearwater are discussed, and the extrime difficulty of making a landfall in llic
trackless ocean is pointed out.

Chapter YII, Aerial Navigatorx, exi)ands the previous chapter. Here the aiitlior
warns against the use of the homing jjigeon as an explanation of thr iKiniiiig lie-
havior of all species. He calls the swallows and others true travelers.

Here is a very interesting discussion of the "internal clock" mechanism which
functions in conjunction with the bird's recognition of the position of the sun. en-
abling it to calculate its position — a method of bio-co-ordinate navigation.

Wiitcnrtn/s, as Chapter YIII, concerns the migrations of eels. North Sea cod.
tunny, salmon, etc. There is a discussion of the recognition of a home stream by a
salmon, which the author inclines to believe is due to dissolved organic substances.
The influence of temperature and salinity changes, currents, inherited direction
sense, magnetic field disturbances, etc., are discussed.

The built-in radar of Gijmnarchus niilotiriis of West Africa and the Nile is a
marvelous mechanism by means of which prey is detected through disturbance of
the magnetic field surrounding the fish. The importance of this in long-range naviga-
tion is minimal.

The Fated Journeii. ("haiiter IX, exjiamls the earlier discussion of mass animal
migrations to include the lemmings, cariboti, Harp seal, whales, etc. A review of
the I'atuxent wild mouse trapping studies is included.

Chapter X. Animal Senses, contains the author's own summing up.

"It is evident that no new .senses have yet been proven to exist : and. in jiarticular,
sensitivity to the earth's magnetic field has not been demonstrated.

"A difficulty which must be overcome in thiid<ing al)out this problem lies in our
desire, conscious or unconscious, to parallel aninmls' with our own. But
willingness to admit the po.ssibility of the superiority of animals' senses in some
directions should not lead us into the realms of fantasy where so many have
wandered while considering the remarkable powers of animals to navigate."

This book is heartily recommended to anyone. The author avoids highly technical
discussions and writes vividly and with an excellent choice of examples. This
reviewer could only wish for a more extensive bibliography, l)ut in turn that would
perhaps remove this book from the realm of general interest and make it a text
suitable only for the sjiecialist. — Harold D. liisseU, Culifoniia Departineni of Fish
and Game.

America's Natural Resources

Edited by Charles H. Callison ; Tln' Ronald I'n-ss ("onipan\. New York, 1!).">T •

vi + 211 p. ,$:;.75.

Many books on the conservation of natural resources have been written in recent
years. This is not just another one. but rather a brief resume of the entire field in
few words by experienced people capable of seeing the problem in its entirety.

It is a well-organized book with wide appeal. For the layman, it represents a brief
and concise introduction to the fundamentals of conservation. For the professional
man, it is useful as an excellent source book, summarizing the highlights of this
most important problem. (Resource specialists need frequently to read books of this
type to retain the proper perspective of the over-all natural resources picture.)

Edited by the Natural Resources Council of America, it brings together a clear, summary of the pertinent facts about America's natural resources and their
conservation. Each topic, such as soil, water, wildlife, etc., is covered in a separate
chapter by a leading authority in the field. These are such men as P'airfield Osl)oru,
Shirley Allen, Albert S. Hazzard, and many other nationally known figures.

Although the chapters were prepared independently, the various authors follow
a similar pattern of exposition in reviewing each resource. This is basically a descriji-
tion of original abundance, the impact of man's activities on the resource, modern
concepts of utilization, followed by what the future holds in store. All are relatively
optimistic about the future, indicating that "when man's activities are so managed
that they will not be detrimental to a continued resource supply, when he has learned


to temper his demands and share in nature's benefits, then the future of our resources
will be assured."

The rapid-moving text, clear type, plus change of style by each author help make
up for the absence of illustrations. This is a book that will serve as an informative
guide for persons wishing to take intelligent action in the defense of our natural
resource heritage. — Willis A. Evans, California Depariment of Fish and Game.

The Living Sea

By John Crompton ; Doubleday & Co., Inc. New York, lO.")!; 234 p., 24 black-and-
white drawings by Denys Ovenden. $3.95.

"An exciting introduction to the sea and its creatures." These words, which ajipear
on the dust jacket, aptly descrilie what the reader will find within.

The author introduces his subject with a brief discussion of the formation of the
earth and its seas and the inception of life. lie tells of the importance of the sea
to all life and the role of plankton in its economy. He traces the evolutionary
processes that enabled animals to make the land their home and follows their
development through the dinosaurs to man. From here we follow the mammals as
they evolve from land forms to sea dwellers, some of which, the whales, spend their
entire lives at sea. Descriptions of the evolution and life history of the foregoing and
many of the important fishes, mollusks, and crustaceans make very interesting

The author's typically British humor adds spice to an already fascinating treat-
ment of a fascinating subject. Mr. Crompton's recognition and forceful expression
of man's destructive effects on animal populations are indeed welcome.

There are a few errors, but they detract little from the value of the book. In the
reviewer's opinion, '"The Living Sea" would prove absorbing and informative reading
to almost anyone. — John L. Baxter, California Depart iiient of Fish and (lame.
