"Without tools man is nothing, with tools he is all."-Carlyle. "The smith came holding in his hands the tools-the instruments of his craft, anvil and hammer and well-made pincers, wherewith he wrought the gold."- "Odyssey," Book III.

The study of the development of tools is one, which, owing to the absence of records referring to their early uses, is necessarily difficult, and direct evolution hard to prove. Study of this subject shows that development of races and of tools may be presumed to have proceeded along very similar lines in different countries at different times. But it should be clearly understood that the definite uses of tools and implements belonging to prehistoric times is largely pure conjecture. To correctly trace evolution in tools is an impossible task regarding prehistoric examples, and the study of tools belonging to a particular country is necessarily largely conjecture in its early stages. It is, however, interesting to note that the "development" of tools and implements, through which may be traced the development of man, has, as indicated above, proceeded in very like ways in countries so far apart as England and Egypt. European developments, in England, Sweden, and Switzerland for instance, exhibit some remarkable sequences of development in design and material. For the purpose of object lessons to handcraft classes the national aspects of the subject are probably sufficient, thus considerably reducing the range of the subject. It is recommended that for purposes of demonstration, wherever possible, large charcoal drawings be made from the actual examples, the drawings being made permanent by the application of some fixing solution and placed on rollers.
