We were approaching the southern hemisphere of Mars in about latitude 45 degrees south. It was near the time of the vernal equinox in that hemisphere of the planet, and under the stimulating influence of the Spring sun, rising higher and higher every day, some such awakening of life and activity upon its surface as occurs on the earth under similar circumstances was evidently going on. Around the South Pole were spread immense fields of snow and ice, gleaming with great brilliance. Cutting deep into the borders of these ice fields, we could see broad channels of open water, indicating the rapid breaking of the grip of the frost. Almost directly beneath us was a broad oval region, light red in color, to which terrestrial astronomers had given the name of Hellas. Toward the south, between Hellas and the borders of the polar ice, was a great belt of darkness that astronomers had always been inclined to regard as a sea. Looking toward the north, we could perceive the immense red expanses of the continents of Mars, with the long curved line of the Syrtis Major, or "The Hour Glass Sea," sweeping through the midst of them toward the north until it disappeared under the horizon. Crossing and recrossing the red continents, in every direction, were the canals of Schiaparelli. Mars Reached at Last--Thrilling Adventures. Plentifully sprinkled over the surface we could see brilliant points, some of dazzling brightness, outshining the daylight. There was also an astonishing variety in the colors of the broad expanses beneath us. Activity, vivacity and beauty, such as we were utterly unprepared to behold, expressed their presence on all sides. The excitement on the flagship and among the other members of the squadron was immense. It was certainly a thrilling scene. Here, right under our feet, lay the world we had come to do battle with. Its appearances, while recalling in some of their broader aspects those which it had presented when viewed from our observatories, were far more strange, complex and wonderful than any astronomer had ever dreamed of. Suppose all of our anticipations about Mars should prove to have been wrong, after all? There could be no longer any question that it was a world which, if not absolutely teeming with inhabitants, like a gigantic ant-hill, at any rate bore on every side the marks of their presence and of their incredible undertakings and achievements. Here and there clouds of smoke arose and spread slowly through the atmosphere beneath us. Floating higher above the surface of the planet were clouds of vapor, assuming the familiar forms of stratus and cumulus with which we were acquainted upon the earth. Dense Clouds Appear.
