However, the conception of this project was far more easy than its execution. It was doing little to choose professors from among the first men of science in Europe, if their lessons were not fixed in the mind of the pupils. Being unable to communicate them to each pupil in private, they stood in need of agents who should transmit them to this numerous assemblage of youth, and be, as it were, the nerves of the body. To form these was the first object.
Among the young men who had presented themselves at the competition, twenty of the most distinguished were selected. Philosophical instruments and a chemical laboratory were provided for them, and they were unremittingly exercised in every part of the plan which it was resolved to execute. These pupils, the greater part of whom had come from the schools for Public Service, felt the insufficiency of the instruction which they had there received. Eager to learn, their mind became inflamed by the presence of the celebrated men who were incessantly with them. The days sufficed not for their zeal; and in three months they were capable of discharging the functions for which they were intended.
Nor was this all. At a time when opinion and power might change from one moment to another, much risk was incurred if a definitive form was not at once given to the Polytechnic School. The authors of this vast project had seen the revolution too near not to be sensible of that truth. But they wished first, by a trial made on a grand scale, to insure their method, class the pupils, and shew what might be expected from them. They therefore developed to them, in rapid lectures, the general plan of instruction.
This plan had been drawn up agreeably to the views of men the best informed, amongst whom MONGE must be particularly mentioned. He had been professor at Mezières, and had there given the first lessons of descriptive geometry, that science so useful to the engineer. The enumeration of the various parts of instruction was reduced to a table, printed by order of the Committee of Public Safety. It comprehends mathematics, analysis applied to descriptive geometry and to the mechanism of solids and fluids, stereotomy, drawing, civil architecture, fortification, general physics, chymistry, mineralogy, and their application to the arts.
In three months, the work of three years was explained. A real enthusiasm was excited in these youths on finding themselves occupied by the sublimest ideas which had employed the mind of man. Amidst the divisions and animosities of political party, it was an interesting sight, to behold four hundred young men, full of confidence and friendship, listening with profound attention to the lectures of the celebrated savans who had been spared by the guillotine.
The results of so great an experiment surpassed the most sanguine expectations. After this preliminary instruction, the pupils were divided into brigades, and education took the course it was intended should follow.
What particularly distinguishes this establishment, is that the pupils not only receive oral lessons, but they must give in written solutions, present drawings, models, or plans for the different parts, and themselves operate in the laboratories.
On the 1st of Germinal year III (22d of March 1795) the annual courses were commenced. They were then distributed for three years, but at this day they last two only. At the same time a decree was passed, regulating the number of professors, adjuncts, ushers, the holding of the meetings of the council of instruction and administration, the functions of the director, administrator, inspector of the studies, secretary of the council, librarian, keepers of the collection of drawings, models, &c.
Since that epoch, the Polytechnic School, often attacked, even in the discussions of the Legislative Body, has maintained its ground by the impression of the reputation of the men who act there as professors, of the depth of the knowledge which makes the object of their lessons, and of the youths of superior talent who issue from it every year. The law which after many adjournments, has fixed its existence is dated the 25th of Frimaire year VIII (16th of December 1799.)
The most important changes introduced, are the determination of the age to be received into this school, which is from sixteen to twenty, the reduction of the pupils to the number of three hundred, the rank which is given them of serjeant of artillery of the first class, their pay fixed on the same footing, together with a fund of assistance for those labouring under difficulties, the obligation to wear a uniform, the establishment of a council of improvement, composed of three members of the National Institute, of examiners, of a general-officer or superior agent of each of the branches of the Public Service, of the director, and four commissioners taken from the council of instruction.
