one in front and two much larger behind, with box-like seat and steering handle; otherwise resembling nothing so much as the velocipedes I have seen ridden for amusement by eccentric English youths.  It was clear, however, that these vehicles were not moved by any effort on the part of their drivers, and their speed was far greater than that of the swiftest mail-coach:—­say, from fifteen to thirty miles an hour.  All risk of collision was avoided, as those proceeding in opposite directions took opposite sides of the road, separated by the raised centre I have described.  Crossing the road with caution, we came upon a number of small houses, perhaps twenty feet square, each standing in the midst of a garden marked out by a narrow ditch, some of them having at either side wings of less height and thrown a little backward.  In the centre of each, and at the end of the wings where these existed, was what seemed to be a door of some translucent material about twelve feet in height.  But I observed that these doors were divided by a scarcely perceptible line up to six feet from the ground, and presently one of these parted, and a figure, closely resembling that of my guide, came out.

We had now reached another road which led apparently towards the larger houses I had seen in the distance, and were proceeding along the raised central pathway, when some half-dozen persons from the cottages followed us.  At a call from my guide, these, and presently as many more, ran after and gathered around us.  I turned, took down my air-gun from my back, and waving it around me, signalled to them to keep back, not choosing to incur the danger of a sudden rush, since their bearing, if not plainly hostile, was not hospitable or friendly.  Thus escorted, but not actually assailed, I passed on for three or four miles, by which time we were among the larger dwellings of which I have spoken.  Each of them stood in grounds enclosed by walls about eight feet high, each of some uniform colour, contrasting agreeably with that chosen for the exterior of the house.  The enclosures varied in size from about six to sixty acres.  The houses were for the most part some twelve feet in height, and from one to four hundred feet square.  On several flat roofs, guarded by low parapets, other persons, all about the size of my guide, now showed themselves, all of them interested, and, as it seemed, somewhat excited by my appearance.  In a few cases groups differently dressed, and, from their somewhat smaller stature, slighter figures, and the long hair here and there visible, probably consisting of women, were gathered on a remoter portion of the roof.  But these, when seen by those in front, were always waived back with an impatient or threatening gesture, and instantly retired.  Presently two or three men more richly dressed than my escort, and in various colours, came out upon the road.  Addressing one of these, I pointed again to the sky, and again endeavoured to describe my journey, holding out to him at the
