The National School of Roads and Bridges, created by Louis XV. in 1741, and developed by different decrees of the two empires, has for its special object the education of young men quitting the Polytechnic School after good examinations as civil engineers. It is placed beneath the authority of the Minister of Public Works, and directed by an Inspector-General of Roads and Bridges. It comprises twenty chairs devoted to different branches of the engineer’s art, without counting drawing--scientific and artistic--and the English and German languages. It contains a laboratory, a library, and a gallery of models to which the public is not admitted. Returning towards the east as far as the Rue Saint-Benoît, we find, on the eastern side of the street, the printing department of the firm of Quantin, in a line with the publishing and administrative departments. At this printing and publishing office, which has given to the world so many fine editions, especially of illustrated books, _Revue des Deux Mondes_ has been printed ever since it first appeared. The art of printing has had a chequered history in Paris, being sometimes protected, sometimes oppressed by the crown, and too frequently crippled by two bodies who, in particular, should have nursed it--the University and the Parliament. It was introduced into the French capital by Allemand La Pierre, prior of the Sorbonne, one of the greatest scholars of his time, and Guillaume Fichet, doctor in theology, who, in 1470, invited Ulrich Gering of Constance, Michel Friburger of Colmar, and Martin Krantz, to come and establish a printing-office within the Sorbonne walls. The three associates acceded to the request, and with the machines they fitted up printed a succession of interesting volumes during their stay at the Sorbonne, which lasted till 1473. Then their establishment was transferred to the Rue Saint-Jacques, under the sign of the “Golden Sun,” beside the church of Saint-Benoît. Here a number of elegant works were produced. In 1484 Friburger and Krantz retired from the concern, in order probably to return to Germany, the name of Gering alone being appended to publications posterior to the month of October in that year. Ultimately the printing-offices were again moved to a house belonging to the Sorbonne, though the sign of the “Golden Sun” was still preserved. Printers now began to multiply rapidly in Paris. One of the most celebrated was Antoine Vérard, who from 1485 published a large number of works, chiefly in French, and remarkable for the beauty of their Gothic characters. Towards the end of 1499, at the period when the Bridge of Notre Dame, on which his house stood, gave way, he removed to a spot near the crossway of Saint-Séverin, afterwards shifting twice more--first to the Rue Saint-Jacques, and then to the Rue Neuve-Notre-Dame, where he remained till his death.
