long is divided into three parts, one being used for an office, the others for stock and tool rooms, respectively. Nine large pits are provided on this floor and there is also ample bench room. This ground floor assembly department is devoted to work that does not involve taking down a car to any extent such as fitting various accessories, tuning or adjusting engines, repairing clutches, brakes, axles, etc., and other work that will not lay up a car for more than a few days. There is a large door at one end to permit cars to enter directly from the street and a smaller entrance at the other leading directly into the passage way in front of the stock room counter over which the patrons are served. There is also a large door opening into the rear of the elevator, permitting cars to run on the elevator when this is in its lowest position, either from the shop interior or from the street.

The upper floor is divided in much the same manner as the lower one, the largest room being used for overhauling purposes, the 36 x 28 feet room is used as a machine shop, while the small room over the office and stock room is used as a forge and tinsmith shop. A large skylight in the roof of the blacksmith shop gives much needed light on the anvil and bench. There are no pits in this floor but, as is the case with the one below, there is an overhead track extending the full length of the room for travelling chain falls attached to the ceiling. The equipment of the machine shop is very complete and enough tools are provided so that it is possible to duplicate any part of any automobile. The equipment shown at Fig. 6 is also very complete.

In the building outlined at Fig. 6 which has been designed exclusively for automobile repair work it will be noticed that the saw tooth roof and the many windows make for maximum daylight illumination. The windows of the saw tooth should always face toward the north to get the best light and prevent annoyance due to the sun shining directly in during the day. The building may be of either brick or concrete and while the arrangement depicted is very good, the plan may be varied to suit individual requirements. It will be observed that there are two main entrances, one a small door, leading directly into the machine shop, while there is a large main door by which the cars enter the repair shop.

and Other Appliances,

It will be noted that the office is placed in such a way that all that goes on in either the machine shop or the assembling department may be seen by the executive or manager. The location of the stock and tool room in the machine shop is logical, as it is most convenient for the men who have frequent need of special tools. The men on the assembling floor usually have their own outfits, whereas the machinists are continually using special drills, taps, dies and cutters that the company must furnish. A person cannot enter the machine shop without first passing the clerk in either the office or the stock room, as wickets in the walls of these rooms forming the passageway open directly into the narrow hall providing access to the machine shop. A pair of large double doors separates the machine shop from the assemblying room as it is often necessary to move in bulky portions of automobiles for attention. In the building shown the boiler room is partitioned off from the assembly room and it is not intended to have any basement. If a cellar is provided, however, the heating boiler may be placed therein and be out of the way. The equipment of the various departments which can be applied to any of the repair shops shown will now be considered in connection with the logical arrangement of the repair shop department.

Arrangement of Departments.-In arranging the departments the layout should be for greatest efficiency and convenience. This applies to the repair shop as much as to the manufacturing plant, and intelligent study will often result in changes which will materially increase efficiency. Many shops are not profitable because of lack of organization and lack of system, while others are handicapped because of poor general arrangement. The owner or manager of a small shop may consider that the installation of a methodical system for record of the cost and progress of the work involves an expense that is unnecessary, and many shops are conducted by a hit or miss principle when simple accounting methods and organization of force would make them much more profitable. Too much system, however, is as bad as not enough, so a happy medium between the two extremes should be adopted. There should be some distinct scheme of organization in every shop of any size, especially in those which employ 18 or 20 men, and this can be advan
