Carpenter work should be encouraged in a boy from the time he first becomes interested in it, for besides being something with which to keep him busy, the experience gained by its practice will be useful to him all his life, no matter what branch of industry he may follow later on. When a boy has learned the proper care and use of tools, and is able to turn out neatly executed work, he will find the occupation a profitable one, there being an unlimited number of things he can make in his shop. Doll-houses for girl relatives, toys for brothers and cousins, and articles for the household, such as are described in following chapters, are a few of the many things he can construct. Many of these are salable articles, besides being suitable for birthday and Christmas gifts, and should bring a neat sum of money to the young carpenter. A knowledge of carpenter work also develops in a boy a handiness for devising and putting together articles and apparatus for his own use.
