The circular railroad passes over the river here on a high brick viaduct, which makes a species of fortification.

The hills outside the city form a sort of amphitheatre, in which are situated the towns of Sevres and Meudon.

To the right of the river is Mont Valerien and the batteries in the Bois de Boulogne; to the left the Fort of Issy.

The noise of the cannonade was very loud; but very little could be seen, owing to the sun shining on the hills outside.

Speculators, however, with telescopes, were offering to show the Prussian artillerymen for one sou--one of them offered to let me see a general for two sous.
