SCHOOL OF BRIDGES AND HIGHWAYS.

It was founded in 1787, by TRUDAINE, and continued under the direction of PERRONET, chief engineer of this corps, till his death, which happened in 1794. He was then 86 years of age. By his will, he bequeathed to this school, for the instruction of the pupils whom he loved as his children, his library, his models, his manuscripts, and his portfolios; articles which at this day form an invaluable collection.

This school, which is at present established in the Hôtel de Chatelet (formerly belonging to the duke of that name) Rue de Grenelle, St. Germain, unites the dépôt or repository of plans and models to the labours relating to roads, canals, and harbours for trade. The number of pupils admitted is fifty. They are taken from the Polytechnic School, and retain the salary which they there received.

The instruction given to them chiefly consists in the application of the principles of physics and mathematics to the art of planning and constructing works relative to roads, canals, and sea-ports, and the buildings belonging thereto; the means of execution, and the mode of forming plans and estimates of the works to be executed, and the order to be observed in keeping the accounts.

The School of Bridges and Highways is under the authority of the Minister of the Interior,

PRACTICAL SCHOOLS OF MINES.

One of these schools is established at Geislautern, in the department of La Sarre; and the other, at Pesay, in the department of Mont-Blanc.

The Director and Professors form a committee for the working of the mines of Pesay, as well as for the instruction of the pupils. In consequence of the report of this committee the Council of Mines established in Paris, proposes to the government the measures necessary to be adopted. Twenty pupils, who have passed their examination at the Polytechnic School, are attached to the practical schools, for the purpose of applying the theoretical part of their instruction. Extra-scholars, with testimonials of good behaviour and capacity, are admitted to be educated at their own expense. These schools are also under the authority of the Minister of the Interior.

SCHOOL OF NAVAL ENGINEERS.

The School of Naval Architects, which existed in Paris, has been removed to Brest, under the name of École des Ingénieurs des Vaisseaux. No pupils are admitted but such as have been students, at least two years, in the Polytechnic School. The examination of the candidates takes place every year, and the preference is given to those who excel in descriptive geometry, mechanics, and the other branches of knowledge appropriated to the first year's study at that school. When the pupils have proved, in the repeated examinations which they must undergo, that they are sufficiently qualified, they are sent to Brest (as vacancies occur), in order to apply the theory they have acquired to the different works carried on in that port, where they find both the example and the precept, and are taught every thing relative to the construction of ships of war and merchant-vessels.
