creased the need for civil engineers, but demands a higher standard of training and education.

There is also pressure from educa- tionists and industry to step up the amount of engineering, scientific and cultural knowledge imparted to stu- dents of engineering. This makes it essential to present the student with a logical sequence of knowledge.

In this book, the author, who is Lecturer in Civil Engineering, Dundee College of Technology, breaks away from the conventional treatment of the subject, and presents a newer, more stream-lined approach.

Here is a publication which should smooth the way for civil engineering students studying the first year of a course in theory of structures.

Ready Mixed Concrete.

Pocket-size

book by Gerhard Grimm, Dipl.- Ing., Professor at the State En- gineering College in Konstanz (Germany). Free of charge from ARBAU, 69 Hoidelberg, Ger- many, Postfach 160.

In view of the increasing import- ance of ready-mixed concrete, the au- thor has undertaken to cover the de- velopment and basic principles of this new article in ten abundantly illus- trated chapters. The booklet deals with all questions concerning the planning, erection and operation of ready-mixed concrete plants.

Among the different technical sub-

jects covered, the one concerning quality safeguards and quality control is dealt with in detail in a separate chapter. The other chapters, too, e.g. the one describing the equipment of a plant laboratory, contain valuable information and help to provide a comprehensive picture of the subject of "ready-mixed concrete".

ate properly because of the inade- quacy of the street pattern, road capa- city and parking facilities (a situation by no means peculiar to Hong Kong) and in fact under present circum- stances the private car should be ban- ned from the central areas at least if there was anything to replace it.

The primitive railway system be- tween Kowloon and the border does not handle the traffic that the size of its installation demands. The most efficient part of the whole system is the ferry element, and leads to thoughts of the possibility of making better use of the water routes, which are the best in the Colony, and as yet not congested. The problem of mass transportation in Hong Kong is how-

ever not without solution; but this solution is bound to be drastic.

Finally in considering transporta- tion and urban pattern, particularly when the prospects look gloomy and there appears to be no solution to traffic problems except frustrating re- striction, hope can be found in the prospect of new transportation sys- tems, both those hitherto undreamed of and those already under study.

One such system is a development of the pneumatic tube system used for message delivery, in which a tube- like vehicle is projected along a tube by compressed air. These transporta- tion systems may be installed under our cities or above them, but what- ever they are, they will certainly in- fluence the urban pattern.

The speed and large carrying capa- city of these new systems will permit the greater spread of the city without the disadvantages to human occupa- tion which this growth produces to- day. Population densities would be reduced and the urban area could again be an attractive environment in which to live.

In all this as was stated at the sum- ming up of the conference, "it is necessary to recognise that transporta- tion is not an end in itself, but a means to an end which is that of achieving a happy, satisfactory human environment for living in our metro- politan cities and urban areas."

...toughest of them all!

No better vehicles exist than these sturdy and economical heavy-duty Commers, which over the years have fully proved their worth in all parts of the world.
