Rural Science. By J. MASON and J. A. Dow. (2s. McDougall.)

An inexpensive little book, carefully written and well adapted to its purpose, which is to provide a three years' course in rural science for schools. The scheme of the book is in accordance with that issued by the Edinburgh and East of Scotland College of Agriculture. This scheme, for which one of the present authors was partly responsible, is of course primarily applicable to Scottish schools, but for the most part is equally suited to those in England. Messrs. Mason and Dow have interpreted the scheme very well and the course they give is clearly the work of experienced teachers who have learnt their pupils' difficulties and how to overcome them.

Murby's Sets of Minerals and Rocks.

Messrs. Thomas Murby & Co. have two sets worthy of the attention of teachers of geography. (1) A set of thirty Economic Minerals and Rocks; (2) a set of thirty Common RocksIgneous, Sedimentary, Metamorphic, &c. These have been selected by Dr. L. Dudley Stamp, Sir Ernest Cassel Reader in Economic Geography in the University of London, who has compiled a booklet of useful notes on each. The sets can be obtained in two forms. One in which the specimens are of specially large size and are thus well adapted for class demonstration; (1) in this form costs £3 7s. 6d.; (2) costs £2 18s. 6d. A set of smaller pieces for pupils' use costs (1) £1 5s.; (2) £1 35. The complete collection should prove of real utility and the enterprise of the publishers deserves high commendation.

New Conceptions in Colloidal Chemistry. By Prof. H. FREUND

LICH. (os. net. Methuen.)

Colloidal chemistry is advancing so rapidly that it is difficult for any one but the specialist to keep abreast of the latest developments. Prof. Freundlich, whose large work on Colloid and Capillary Chemistry was recently reviewed in these columns, is not only one of the chief authorities on the subject, but has a marked capacity of clear exposition. We can heartily recommend this book to those teachers of physics or chemistry who realize the importance of colloid chemistry but have allowed themselves to become rusty.

Compulsory Teaching of Chemistry in Schools. By M KOSTER.

(Is. net. Bale.)

A forceful exposition of the view that, since chemistry plays such a vital part in modern civilization, every boy or girl should be taught something of it at school. Whether Mr. Koster will carry conviction or not is another matter; it seems to us that he bases his arguments far too much on the material side of the problem, forgetting that the prime object of teaching science in schools is education in its widest sense. However, the little pamphlet is well worth reading and is likely to provoke a good deal of discussion.

Practical Physics. By T. G. BEDFORD. (10s. 6d. net. Longmans.) The course described in this volume is based upon the set of experiments which have been provided in recent years for the students, mostly in their first year at the university, who have attended the author's classes at the Cavendish Laboratory, Cambridge. An important feature is the explanatory matter, on the theory of the practical work, which has been added in all cases where this might be found useful. For the most part, the apparatus described is simple, and not beyond the resources of the average laboratory. The volume can be recommended as a most useful guide, both to teachers and to students.

Forest, Steppe, and Tundra: Studies in Animal Environment. By MAUD D. HAVILAND (Mrs. H. H. BRINDLEY). (12s. 6d. net. Cambridge University Press.)

To appreciate these ecological essays a considerable knowledge of zoology and a modicum of botany are essential. The reader thus equipped will find in these pages a host of good things bearing on adaptation to environment, and on other matters of general biological interest. Mrs. Brindley has woven her own observations with those of previous workers in these strikingly diverse regions; and gives a full bibliography for each. Her book is more suitable to post-graduate than to school days.

Health: A Textbook for Schools. By M. AVERY. (6s. Methuen.) Within recent years resolutions in favour of hygiene finding a place in the curriculum have been passed by the Headmasters' Conference, and by the Conference of Headmistresses. This book is a level-headed presentment of the need for public and for personal hygiene, and of the steps and conduct necessary to secure them. It is suitable for use in upper forms of secondary and public schools, but should be read by every one who wishes to know what has been achieved in the past, what still requires

to be done for the sake of humanity, and the part that he (or she) should play in the hygienic fight.

The Home Preservation of Fruit and Vegetables. By MARGARET

J. M. WATSON. (6s. net. Oxford University Press.) We should like to see this book in the hands of, and its methods adopted by every fruit-grower and market-gardener in this country. Much of the deplorable loss and wastage that occurs in a "good" year for any given crop could be avoided if these methods of preservation were adopted. The book is based on courses given by the authoress at the Campden Research Station, and is primarily intended for students of domestic science, horticulture, &c., but any whose gardens ever produce more than is at the moment necessary for the household will find it invaluable for every kind of preservable produce.

The Birds of the British Isles. Third Series: Comprising their Migration and Habits, and Observations on our Rarer Visitants. By T. A. COWARD. (IOS. 6d. net. Warne.) Interest in bird-migration is so widespread that this handy volume will be welcomed by a large circle of readers to whom the extensive literature on the subject has been hitherto inaccessible. Mr. Coward, than whom there is no higher authority, here first gives us an epitome of the observed facts, and a most valuable expression of his own considered opinion regarding them, and then deals with all the birds on the British list, treating them in families, and stating when they appear in Britain, whence they come, and frequently their courtship and other habits. The illustrations, both coloured and photographic, are excellent; the former being by Archibald Thorburn, or reproduced from Lord Lilford's great work.

Elementary Botany: an Introduction to the Study of Plant Life.

By Dr. W. WATSON. (6s. 6d. Arnold.) This pleasantly-written book is serviceable both in school (class-room and laboratory) and in the field, and is successful in correlating the two types of work. A good feature is the association of plant physiology with morphological features as these come under observation, instead of devoting any chapters exclusively to physiology. It is certainly right to combine the study of structure with function; though in practice it is not always easy.

MISCELLANEOUS

Practical Social Science : A Laboratory Text-book. By Dr. J. A. LAPP. (7s. net. New York: Macmillan.)

A book of this kind brings home to English readers the difference between American and English secondary schools. It is a text-book for the use of boys and girls, giving the essential data of social science in the concrete," together with a very large number of problems which can be solved by the correct handling and interpreting of the data. The aim of the writer is to train the students for intelligent citizenship, as well as to prepare them for more advanced work in sociology. The subjects are grouped under four main heads, The Citizen and Society, Production, Social Welfare, Community Work, and are in every case amply illustrated by charts and tables, taken from official publications.

The Book of the Aeroplane. By Captain J. L. PRITCHARD, (7s. 6d. net. Longmans.)

The author of this very readable volume is a well-known writer on aeronautical topics. Within the compass of 255 pages we are led through a popular survey of all that is interesting and important in this latest of technical developments. Beginning with an historical introduction-with a reminder that it was Wilbur Wright's dictum that "the bird which talks most is the parrot, and is the bird which flies least '"-we are taken successively through chapters on why an aeroplane flies, famous flights, races, and records, ground organization, safety problems, aeroplane types, construction problems, and aeroplane engines. Finally we have a survey of the aeroplane in war and the problems of the future. The book is well illustrated with plates and diagrams, and we recommend it to all school libraries.

Stability and Seaworthiness of Ships: A Text-book for Officers of the Mercantile Marine and for all Concerned with the Loading of Ships. By Prof. T. B. ABELL. (18s. net. University Press of Liverpool. Hodder & Stoughton.) Both the Univ

University of Liverpool Press and Prof. Abell are to be congratulated on this excellent volume, which fittingly emanates from a "sea-board" university. The work is clearly written, well-produced, and sufficiently elementary in its mathematical treatment to enable it to be studied with advantage by the various classes of readers for whom it is mainly intendedthose who have to prepare a ship at its loading port, those who have to navigate it, and the marine engineer officers who have charge of the appliances for securing stability.

Pros and Cons: a Newspaper Reader's and Debater's Guide to the leading Controversies of the Day (Political, Social, etc.). Seventh Edition. By H. CoUSENS. (2s. 6d. net. Routledge.) There is a marked tendency in these times to forswear permanent labels, political or other, and to consider public questions on their merits, as they arise. To this tendency, which one can scarcely help approving, this small volume will minister. It ranges over a very wide field, from total abstinence to coeducation, and from direct action to the sterilization of the unfit. Some one has said that a man is well educated when he cannot be humbugged by a newspaper. If that is so, this book will help on the cause of education.

(1) Metal-Work. By H. M. ADAM and J. H. EVANS. (6s. 6d. net. Arnold.)

(2) Printing and Book Crafts for Schools. By F. Goodyear. (Ios. 6d. net. Harrap.)

(3) Pictorial House Modelling: a Practical Manual Explaining how to make Models of Buildings. By E. W. HOBBS. (6s. net. Lockwood.)

(1) This is a new edition of a book well known to manual training instructors and, while it is impossible to treat metal work adequately in some 270 pages, the authors have collected here most of the information necessary for elementary classes. We are glad to see that the formal course of exercises and suggestions for models have been omitted from this edition, for, in our opinion, anything which would tend to stereotype a set of models and exercises is educationally wrong. The instructor must be free to invent, to modify, and, wherever possible, to allow full scope to his pupils' ideas. (2) Printing and bookbinding are comparatively new in junior handicraft schools, but are very valuable in developing manual dexterity and skill and in affording scope for really useful occupations which are well suited to those who find woodwork and metalwork too difficult.

PUBLICATIONS

Mr. Goodyear has treated the elementary parts of his subject admirably, and any handicraft instructor who is seeking new worlds to conquer will be well advised to add this little book to his library. Some of the illustrations are inartistic and might well be replaced by others in future editions, but technically the book is quite satisfactory and contains under one cover much information otherwise difficult to obtain. (3) Some of the suggestions in this book will be found useful for pupils who are well advanced in cardboard modelling, but the scheme is too haphazard and the details too elaborate for school work.

Letters of George Gissing to Members of his Family. Collected

and Arranged by ALGERnon and Ellen Gissing.
net. Constable.)

(185.

Readers who belong to Gissing's generation will turn the pages of this book with pathetic interest. They will remember him as the scholarly recluse, who scorned the opinions of the multitude, lived hard, wrote hard, and died young. During the brief three and twenty years of his literary life, he produced nearly as many novels, at least half of which are of a kind which the educated world will not willingly let die. These letters help very materially to fill out the picture of Gissing that his admirers had so far been able to form, and help also to relieve the sombreness of that picture by showing us Gissing as the affectionate son and brother.
