To encourage readers to "use their hands" the following chapters have been written. The subjects chosen provide ample scope for the exercise of ingenuity and patience; but in making my selection I have kept before me the fact that a well-equipped workshop falls to the lot of but a few of the boys who are anxious to develop into amateur craftsmen. Therefore, while the easiest tasks set herein are very easy, the most difficult will not be found to demand a very high degree of skill, or more than a very moderate outlay on tools. I may say here that I have been over the ground myself to find out its difficulties for my readers, and that I made an engine similar to that described in Chapter XV (the most elaborate mechanism included in the book) with very simple tools. Some of the items which I had on my original list were abandoned, because they presupposed the possession of comparatively expensive machines.
Archibald Williams (1871–1934) was English technical journalist and Fellow of the Royal Geographical Society.
He was living at 82 Mattock Lane , Ealing , London and was a well-known author of boys' books ', including the popular "How it Works" series. The net vaue of his estate was £4686, gross, £ 4743 net. He died in Ealing.
Note: Williams was born in the Faringdon district that spans the boundaries of the counties of Wiltshire, Gloucestershire, Oxfordshire and Berkshire in the September (fourth) quarter of 1871 and died in Ealing in the September (fourth) quarter of 1934. As no exact date of birth and death is known, the first date of the fourth quarter is used to complete the field in both cases.
