Nothing is more useful to a youth than to be able to do a little carpentering. To be handy with a chisel and saw, a nail and a hammer, saves many a dollar in the course of the year. If you call in a carpenter for a little work he is sure to spin out a “regular job.” I remember once buying some oak saplings, which cost me fifteen cents a stick; and wanting to build a summer-house, I required eight of them to be sawn through, so I applied to a carpenter, and the sticks were cut, but, to my astonishment, four dollars was charged for this little “job,” although the wood cost me only one dollar and thirty cents. I found out afterwards that the proper price for sawing would have amounted to about one dollar, so that three dollars profit was clapped on for the benefit of my experience. I just mention this to show my young friends that if they wish to make summer-houses for their gardens, cages for their birds, fowl-houses, rabbit-hutches, or boxes for their books, they must learn to make them for themselves. I shall therefore offer them a little advice upon “carpentering.”
Endeavor to procure some small outhouse, in which you may erect what is called a carpenter’s or joiner’s bench. These may very often be bought second-hand, or if not, can easily be procured at a reasonable rate. I am very particular in recommending a bench, as without it you will find many obstacles to your work. You must also provide yourself with a set of tools,—gimlets, hammers, planes, saws, gouges, files, nails, screws, and such articles of use.
