THIS is the eleventh edition of an excellent and most useful book for engineers and students in the engineering departments in our technical colleges. Prof. Unwin is so well known in the profession that any work of his is sure to receive full attention and careful study; for even in the present day one unfortunately often sees machinery and engineers' tools, the design and construction of which give us cause to wonder how they manage to work at all. The author is one of those Professors whose books are eagerly sought after by practical men for guidance. To say this is to say very much indeed, for engineers have to make their machines “pay” and creditable to themselves; a bad machine tool in a shop is very soon found out by the repairs it requires, and the quality of the work it can produce.
