On a subsequent occasion the writer was shown a close-up view of Urid. Flowers, grass and green foliage abounded everywhere. The long streets were broad and well paved, and flanked on two sides with long rows of one-storied buildings of white stone, beautiful in their simplicity. No extreme ornamentation is carried out in the erection of buildings on Mars. On the contrary, the simple square outlines characteristic of our own Old Mission architecture seems to prevail on the planet Mars. The same simple style prevails with the public buildings, except that massive stone columns marked the portals of same, reminding one of our own early Grecian architecture. Many palm-like trees grew all over the city, especially in the neighborhood of the public buildings. A week after the occurrence of the above incident the writer was shown, in the same manner as before, one of the many canals that gridiron the Martian globe. This particular canal is one of the main waterways on Mars, and appeared to be about a mile wide at the point of observation. The water was of a deep blue color, denoting great depth. Along the banks of this waterway could be seen many houseboats or floating dwellings. Some of these houseboats were very large and evidently housed large families. The writer was informed that many Martians who have charge of the waterways dwell in these habitations. The banks above the canal were covered with green grass and many flowers. On subsequent occasions I was shown other canals and reservoirs, and the manner in which some of the canals were cut through the mountains. In some instances the walls of the canals were almost perpendicular. Steep cuts, even in soft ground, seemed to be characteristic of all the waterways observed by the writer. On another occasion the writer was given a view of the North Polar regions. At that time the deep snows that covered the ground everywhere were melting. The country seemed to be very hilly. As far as the eye could reach I observed low-lying hills covered with a white mantle of snow. Patches of reddish earth here and there indicated that the thaw was general and that the snow had thinned out in spots. Between the hills I observed a large body of water, and was informed that this was an artificial reservoir which had been created by the damming of a large valley. The sky on this occasion was hidden by a mist, a very natural phenomenon in view of the fact that many thousands of square miles of the country, covered with snow on this part of Mars, was undergoing a rapid thaw. That the large dark-colored areas on Mars, supposed by early observers to be seas, are nothing more or less than low, swampy land covered with rank vegetation, was evidenced to me on one occasion when I was permitted to see the true character of these portions of the planet.
