Competition still continued, so productive is a line on which are little towns like Saint-Denis and Saint-Brice, and villages like Pierrefitte, Groslay, Ecouen, Poncelles, Moisselles, Monsoult, Maffliers, Franconville, Presles, Nointel, Nerville, etc.

The Touchard coaches finally extended their route to Chambly; but competition followed.

To-day the Toulouse, a rival enterprise, goes as far as Beauvais.
Along this route, which is that toward England, there lies a road which turns off at a place well-named, in view of its topography, The Cave, and leads through a most delightful valley in the basin of the Oise to the little town of Isle-Adam, doubly celebrated as the cradle of the family, now extinct, of Isle-Adam, and also as the former residence of the Bourbon-Contis.

Isle-Adam is a little town flanked by two large villages, Nogent and Parmain, both remarkable for splendid quarries, which have furnished material for many of the finest buildings in modern Paris and in foreign lands,--for the base and capital of the columns of the Brussels theatre are of Nogent stone.

Though remarkable for its beautiful sites, for the famous chateaux which princes, monks, and designers have built, such as Cassan, Stors, Le Val, Nointel, Persan, etc., this region had escaped competition in 1822, and was reached by two coaches only, working more or less in harmony.
This exception to the rule of rivalry was founded on reasons that are easy to understand.
