Amateur Work readers will be better able to follow the trend of these articles if each name and address is checked off on the map given in last month's issue as these locations will be referred to many times during the progress of the work.

It will be observed that the town has been pretty well covered, and that wires will have to be placed on every street in town, but in certain cases over private ground to save wire expense.

As the purpose of the company is to supply telephone service at a minimum of expense and labor, it is decided to utilize all substantial trees on the highways, where possible, a proposition which would not meet with approval in many larger communities, but quite worthy of introduction in Jefferson, where the trees furnish an unusual opportunity for such practice. As to line construction, it is deemed advisable to secure the services of one able telephone construction employe to supervise the undertaking, and thus lessen the possibilities of error. It is an easy matter to secure the services of such an expert through the medium of the supply house furnishing the stock of instruments and fixtures, and such procedure will always be found cheapest in the end, even though the wages paid for expert help seem somewhat high. One capable foreman can direct the work of a dozen inexperienced hands in stringing wire, setting poles, and the the like, the gang of men thereby accomplishing more in two days than they could in a week if alone and unaided.

Such poles as are required at street corners may be cut in the nearest timber section, from which they can be purchased.

The Jefferson central office is at the general store at the center. Provision is made for the switch-board in a corner near the Post Office section and book-keeping desk, where it is convenient for the clerks to answer the calls. This matter of having the calls answered by several, appears to a certain extent primitive and unbusinesslike, but the calls will be few and far between at first. Should the business increase sufficiently, a permanent operator may be stationed at the switchboard, at least during the busiest part of the day.

In the selection of equipment for the central office and the sub-stations, the merits of several makes of apparatus have been carefully looked into, in several cases it being difficult to discriminate between them, but in view of the fact that one system provides means of signalling between parties on the same party line, without operating the drop signal at central, a purchase of twenty complete sets of subscribers' instruments of the wall type, and a 50 line switchboard equipped for this service, is assumed to have been made.

The subscribers' instruments are of the type known as 5-bar, 1600 ohm bridging, with a push button installed on each set, so that in turning the generator the ringing current may be sent grounded or metallic upon the line. When ringing central, the push button is pushed while ringing, which rings through one side of the ground, thereby calling central without ringing any of the bells on the line, and in ringing various calls on the line the button is left normal, the subscriber turning the generator as usual. This feature eliminates a portion of the ringing on each line and also permits parties desirous of transacting much business together to locate on the same party line.

A sketch of this circuit may not be out of place, as the engraving of the instrument shown in this article does not illustrate the push-button feature, which is at the left on the bell box. Apparatus of this type is set up by special arrangements with the factory.

The price of each subscriber's outfit is $11.25 net in quantities of 26. The instrument is similar to the conventional Bell type of wall set, with transmitter fitted to an extending arm, generator above and batteries in the box below. The metal work is nickel and black enamel. The woodwork is oak or mahogany, as preferred. In the cut of the instrument wet batteries are shown. It is the general opinion of telephone men of today that the dry battery answers all the requirements, and in the Jefferson installation, where maintainance expense must be cut to a minimum, the wet type of cell will be replaced with the dry.
