The burial of the rats

Leaving Paris by the Orleans road, cross the Enceinte, and, turning to the right, you find yourself in a somewhat wild and not at all savoury district. Right and left, before and behind, on every side rise great heaps of dust and waste accumulated by the process of time. Paris has its night as well as its day life, and the sojourner who enters his hotel in the Rue de Rivoli or the Rue St. Honore late at night or leaves it early in the morning, can guess, in coming near Montrouge-if he has not done so already-the purpose of those great waggons that look like boilers on wheels which he finds halting everywhere as he passes.
