One is apt in selecting an oil can to think that the more expensive sorts are the best. This is not always the case. For use on the bench, when oil is used only for oilstones, a very small and light can is better than a large heavy one. A can a little larger than those usually furnished with sewing machines is a good size. The hole in the spout should be quite small. It is far easier to take the necessary time to let oil flow from a small opening than to wipe up the excess which is sure to flow from a large spout with a large opening. Neatness and economy in the use of oil will help one to become neat and economical in the use of other materials. Be very careful in filling the can not to get any dirt into it, for a very small bit of dirt may stop the spout and cause a good bit of trouble.
