I had already noticed, during the conversation, that our aërial conveyance had assumed a gentle swinging position; and when Bacon paused in his remarks, Miss Phantasia cried to me, "Do, now, apply your eye to these pseudo-cannons, and tell us, pray, where we are." I found at once that those tubes which I had mistaken for cannons were enormous telescopes; but my mistake was pardonable enough, so far as their outward appearance went. They were certainly much wider, from which I concluded, à priori, that they must be powerful machines; but when I came to look through them, I discovered that their great width did in no way interfere with the sharp outlines of the images, and I was not only very much struck with their immense magnifying power, but at the same time with their great extent of the field of vision. Following Miss Phantasia's finger direction, the first thing I saw before me through the telescope at the stern of the vessel was an immense city, which I fancied could be no other than Londinia, from whence we had started. A vast cluster or mass of houses presented itself, with the sharpest outline, in the somewhat dull background, but no idea of smoke; I therefore concluded that wherever coals were still used, one knew how to pass the smoke through the cowl or fire-grate in accordance with the wise Act of Parliament passed in 1850. As I looked through the different telescopes which we had on board, I could not help admiring the scenery around and about us, which seemed to rush and rush on before our eyes whilst the ship was apparently lying still. Ascending, it was as if the earth went down beneath us. Shortly after, we caught the first glance of the sea, and right before us, opposite, we perceived the Belgian and French coasts. A black wire seemed to cross the narrowest strait of the Channel, so as to join the two opposite shores together. Channel Bridge. As we came nearer I began to suspect that this wire might be a tubular bridge of some kind, and this surmise grew into certainty when Bacon assured me that a company had already been formed for the purpose of constructing a second one; "for," added my informant, "this one has become utterly inadequate to the extensive communication between England and the continent." North Holland Submerged. A slight north-north-easterly direction, and a few minutes sufficed to bring us near to my native home, which to us, from our vessel, looked like its outline in an atlas. Only how terrified I was to see that there was something wanting on the map. The whole province of North Holland, [12] minus a few diminutive islands, seemed to have disappeared. Not even trusting my eyes, I asked the "trunculant figure" who, Bacon said, was my countryman: Was the whole of North Holland imbedded in the sea?
