When I broached to Nadar the subject of the postal regulations in regard to the weight and size of letters, he genially replied: "Leave that to me. Your packets need not go through the ordinary post at all--at least, here in Paris. Have them stamped, however, bring them whenever a balloon is about to sail, and I will see that the aeronaut takes them in his pocket. Wherever he alights they will be posted, like the letters in the official bags." That plan was carried out, and although several balloons were lost or fell within the German lines, only one small packet of sketches, which, on account of urgency, had not been photographed, remained subsequently unaccounted for. In all other instances either the original drawing or one of the photographic copies of it reached London safely. The very first balloon to leave Paris (in the early days of October) was precisely Nadar's "Neptune," which had originally been intended for purposes of military observation. One day when I was with Nadar on the Place Saint Pierre, he took me up in it. I found the experience a novel but not a pleasing one, for all my life I have had a tendency to vertigo when ascending to any unusual height. I remember that it was a clear day, and that we had a fine bird's-eye view of Paris on the one hand and of the plain of Saint Denis on the other, but I confess that I felt out of-my element, and was glad to set foot on _terra firma_ once more. From that day I was quite content to view the ascent of one and another balloon, without feeling any desire to get out of Paris by its aerial transport service. I must have witnessed the departure of practically all the balloons which left Paris until I myself quitted the city in November. The arrangements made with Nadar were perfected, and something very similar was contrived with the Godard brothers, the upshot being that we were always forewarned whenever it was proposed to send off a balloon. Sometimes we received by messenger, in the evening, an intimation that a balloon would start at daybreak on the morrow. Sometimes we were roused in the small hours of the morning, when everything intended for despatch had to be hastily got together and carried at once to the starting-place, such, for instance, as the Northern or the Orleans railway terminus, both being at a considerable distance from our flat in the Rue de Miromesnil. Those were by no means agreeable walks, especially when the cold weather had set in, as it did early that autumn; and every now and again at the end of the journey one found that it had been made in vain, for, the wind having shifted at the last moment, the departure of the balloon had been postponed. Of course, the only thing to be done was to trudge back home again. There was no omnibus service, all the horses having been requisitioned, and in the latter part of October there were not more than a couple of dozen cabs (drawn by decrepit animals) still plying for hire in all Paris.
