From the Cave, the point on the route to England where a paved road (due to the luxury of the Princes of Conti) turned off to Isle-Adam, the distance is six miles.

No speculating enterprise would make such a detour, for Isle-Adam was the terminus of the road, which did not go beyond it.

Of late years, another road has been made between the valley of Montmorency and the valley of the Oise; but in 1822 the only road which led to Isle-Adam was the paved highway of the Princes of Conti.

Pierrotin and his colleague reigned, therefore, from Paris to Isle-Adam, beloved by every one along the way.

Pierrotin's vehicle, together with that of his comrade, and Pierrotin himself, were so well known that even the inhabitants on the main road as far as the Cave were in the habit of using them; for there was always better chance of a seat to be had than in the Beaumont coaches, which were almost always full.
