This is a subject in which every boy is interested. While fewmechanics have the opportunity to actually build an automobile,it is the knowledge which he must acquire about every particulardevice used, that enables him to repair and put such machines inorder. The aim of this book is to make the boy acquainted witheach element, so that he may understand why it is made in thatspecial way, and what the advantages and disadvantages are ofthe different types. To that end each structure is shown indetail as much as possible, and the parts separated so as togive a clear insight of the different functions, all of which areexplained by original drawings specially prepared to aid the reader.

This work is not intended to set forth the exploits of aviatorsnor to give a history of the Art. It is a book of instructions intendedto point out the theories of flying, as given by the pioneers,the practical application of power to the various flying structures;how they are built; the different methods of controlling them;the advantages and disadvantages of the types now in use; andsuggestions as to the directions in which improvements are required.It distinctly points out wherein mechanical flight differsfrom bird flight, and what are the relations of shape, form, sizeand weight. It treats of kites, gliders and model aeroplanes,and has an interesting chapter on the aeroplane and its uses inthe great war. All the illustrations have been specially preparedfor the work.
