Industrial establishments may be classified broadly under jobbing shops and manufacturing shops. In the former, absolutely identical jobs may not be repeated more than a few times in 12 months. On the other hand, in the latter, the same processes may he repeated day after day without variation during the entire year. To the former class belong practically all the shops operated by the Navy Department. Selecting the machinery for doing jobbing work economically is naturally much more difficult than selecting the machinery for a shop which turns out only one or two standard articles. In the case of the latter the processes involved in making the articles are definitely known beforehand and only the exact equipment required to accomplish these processes need be installed.
