That remark was made in the shop, and was pretty near correct. Outside of the shop no one ever thinks of calling anything a screw driver except the instrument used to turn slotted screws. I had almost said wood screws, but that would have discarded the screw driver most in sight, that little convenience that comes, and goes, with every sewing machine, to tempt the operators to get them out of repair, and which, it is needless to say, isn’t, sometimes, worth the powder it would take to blow it to Chic—, but after all, it serves its purpose—what more would you want? And it is used by more people than any other mechanical instrument.
In fact few domestic screw drivers are just what they should be; and carpenters screw drivers are not much better. Wood screws are of various lengths and sizes. You can get little bits of wood screws, an inch long, or you can get them, just the same length, as big as a lead pencil.
Here are half a dozen estrays now on my desk while I write; how, whence, or when they came I don’t know. They will do for samples, and they vary from an eighth to more than a quarter of an inch in size. Now it don’t stand to reason that the little screw—not much bigger than a knitting needle, requires the same size and kind of a screw driver that the big one does.
