THE MUNICIPAL SCHOOL FOR INSTRUCTION IN WATCH-MAKING, AT GENEVA.

When, in 1587, Charles Cusin, of Autun, settled at Geneva and introduced

the manufacture of watches there, he had no idea of the extraordinary

development that this new industry was to assume. At the end of the

seventeenth century this city already contained a hundred master watch

makers and eighty master jewelers, and the products of her manufactures

soon became known and appreciated by the whole world.

The French revolution arrested this impetus, but the entrance of the

Canton of Geneva into the Confederation in 1814, rendered commerce, the

arts, and the industries somewhat active, and watch-making soon saw a new

era of prosperity dawning.

On the 13th of Feb., 1824, at the instigation of a few devoted citizens,

the industrial section of the Society of Arts adopted the resolution to

form a watch-making school, which, having been created by private

initiative, was only sustained through considerable sacrifices.

[Illustration: CLASS IN ESCAPEMENTS AT THE WATCH MAKING SCHOOL, GENEVA.]

In 1840 the school was transferred to the granary building belonging to

the city. In 1842, when it contained about fifty pupils, it was made over

to the administrative council of the city by the committee of the Society

of Arts. From 1824 to 1842 the school had given instruction to about two

hundred pupils. From 1843 to 1879 it was frequented by nearly eight

hundred pupils, two-thirds of whom were Genevans, and the other third

Swiss of other cantons and foreigners.

The school, then, has furnished the watch-making industry with the

respectable number of a thousand workmen, among whom large numbers have

been, or are yet, distinguished artists.

The rooms of the granary, where the school remained for nearly forty

years, became inadequate, despite the successive additions that had been

made to them, and it became necessary to completely transform them. The

magnificent legacy that the city owes to the munificence of the Duke of

Brunswick was partly employed in the reorganization, and the school is now

located in a vast building designed to answer the requirements of

instruction. This structure, which is located in Necker Street, presents

an imposing and severe aspect. The main building embraces most of the

workshops, the office, the library, and the classroom for instruction in

mechanics, all of which receive a direct light. At right angles with the

main building are two wings. The one to the north contains in its three

upper stories workshops occupied by classes in escapements, bezil setting,

compensating balances, and ruby working. On the ground floor are installed

juvenile schools.

The south wing contains halls for lectures on theory, and two workshops

looking toward the north. The ground floor is used for the same purpose as

that of the north wing.

Finally, in the center of the main building is a wing parallel with its

two mates. It is in this that is located the vast staircase that leads to

spacious landings at which ends on every story a large corridor common to

all the halls and workshops. It is in this part of the building that we

find the amphitheater of physics and chemistry and the laboratories. Here

also is located the museum in course of formation (gotten up in view of

the historical study of watch-making), and the amphitheater designed for

certain public lecture courses.

In the way of heating and lighting all parts of the building nothing has

been neglected, and special care has been taken to have the ventilation

perfect.

At present the instruction comprises a practical and a theoretical course.

_Practical Instruction_.--This is divided into three sections: (1) an

elementary one having in view the construction of the simple watch in its

essential parts; (2) a higher section in which the pupils learn to

recognize the complicated parts; and (3) a section of mechanics applied to

watch-making and to the study of the construction of machines and tools

for facilitating and improving the manufacture.

1. _Elementary Section, First Year_.--The pupil must manufacture all the

small tools necessary for making unfinished movements; that is, drills,

reamers, punches, files, etc. He must then learn to file and turn, and to

make use of the finishing lathe with the bow, or of the foot lathe.

In general, the time taken by an apprentice to manufacture his tools is

from two to three months, and he can scarcely go to work on the movements

before this.

In this class the regular pupils have to execute seven pieces of work in

the rough, two for horizontal escapements with key and regulating wheel,

and five for various other escapements. Among these there is one for

simple repetition and one for minute piece. Aside from the work fixed by

the programme, the pupils may manufacture all the other complicated pieces

upon obtaining the authority for it from their masters and the director.

The average time employed in performing the work imposed by the programme

necessarily depends upon the capacity of the pupil, but we may say that in

general ten months are necessary.

_Second Year_.--After executing his last piece of work in a satisfactory

manner, the apprentice passes into the class in regulators, where he

begins to manufacture the small tools that he will require.

In this work, as in the preceding, he must take all his pieces from the

crude metal, and he must do the forging himself, as well as the roughing

down, the turning, filing, and shaping, and finally the finishing, without

the aid of any other machine than the dividing one.

In general, after eighteen months of work, the apprentice goes to the

finishing shop, where the delicate and minute work begins, pivoting,

putting the wheels in place, and practical study of gearings. After

learning how to divide a wheel correctly, he is set to work on pinions and

wheels in the rough, which he must rivet, finish, and pivot according to

the different planes of the pieces that have been calculated and executed

by him under the direction of the master.

The programme to be followed by the pupils of the class in finishing is,

as regards number of pieces, the same as that of the preceding classes,

that is to say, seven.

In general, the pupil passes from the class in finishing to the class in

dial-trains, where he makes two of these for his pieces--one a simple and

the other a minute train. The teaching of this part is very important as

regards the manufacture of escapements. In constructing the dial train,

the pupil perfects his filing and learns to make the adjustments correct.

The last class in the elementary instruction is the one in escapements

(Fig. 1), the programme of which includes several distinct parts: (1) The

tools that are strictly necessary; (2) escapement and cylinder adjustment;

(3) making the compensating balances for the pupil's pieces; (4) pivoting,

putting in place, and finishing the escapements in regulating pieces.

Here, as in the preceding classes, the pupils must do all the work

themselves. During their stay in the elementary classes the work done is

submitted to the director, who examines it and sends it back to the

instructors accompanied with a bulletin containing his estimate as to its

value, and his observations if there is occasion to make any.

Pupils who cannot or who do not wish to go over the entire field of the

programme stop here, and are now capable of earning their living and of

lightening the load that oppresses their parents.--_Science et Nature_.
