MARS AS YOU APPROACH IT, SHOWING THE CANALS.
On approaching Mars we should behold a world looking in some respects remarkably like the earth, having seasons resembling ours, with torrid, temperate, and frigid zones; turning on its axis like our globe, and in nearly the same time; showing in winter broad white caps, as of snow, covering its polar regions, and presenting many appearances suggestive of continents, oceans, islands, and peninsulas. As we watched it slowly turning under our eyes, we should see on one side, south of its equator, a huge, staring eyelike-spot, which Schiaparelli has named the "Lake of the Sun," and on the opposite side, reaching from the southern hemisphere into the northern, a great, dark, crooked area, somewhat resembling North America in shape, and known to astronomers as the "Hour-glass Sea." And then all the globe beneath us would appear to be mapped with delicate reds and yellows and grays and blues; long waving curves and sharper indentations would make their appearance in what look like coast-lines; and presently, running east and west and south and north, and passing "beyond the horizon's utmost rim," a network of dark-colored lines, like a vast web covering the planet, would be seen. These are the famous "canals."
But while we were wondering what this could mean, we should be struck by another unearthlike thing. Being accustomed to dwell on a globe three-fourths of whose surface is covered with water, it could not escape our notice that the world we were approaching had far more land than water. Indeed, it is likely that we should find that the "Hour-glass Sea," and many of the other so-called seas of Mars, are only part of the time filled with water, and that even then they are not like terrestrial oceans, but rather vast swamps, choked with rank vegetation suddenly awakened to life by periodical inundations supplying moisture to their roots. Visiting them at another time, we should find only deserts with cracked soil baking in the sun. At any rate, some of the discoveries made with great telescopes in 1894 suggest these things.
In the equatorial regions, where the earth is richest in all forms of life, it is not improbable that we should find Mars covered with one vast Sahara. We should have to go to the poles to discover anything like seas. When the snow-fields around the south pole began to melt away with the on-coming of summer, an opportunity would be given us to behold a spectacle that the earth cannot match. As the snow melted, the water thus formed would collect into a shallow sea, which would constantly tend to empty itself by flowing off toward the equator. Very likely Mars is a remarkably flat world, and the water from the pole would encounter little opposition to its movement.
Then would come a sight that would open our eyes with amazement. Looking toward the equator, we should see only barren red lands and the dry and dusty basins of ancient seas; but the wave of snow-water from the antarctic circle, running through ready channels and percolating the thirsty soil, would be like the spirit of life moving upon the face of a dying world. At its touch vegetation would sprout and spring and wax great, with the magic rapidity that we sometimes see exhibited on the earth; the hard soil at its roots would fall apart and dissolve with moisture, and in a few weeks, where only the naked bones of the planet had been visible before, we should be able to wade neck-deep in seas of verdure, with long grasses waving softly in the vernal wind, and sweet flowers stroking our faces.
The observations made by Mr. Percival Lowell and Professor W. H. Pickering during the last opposition of Mars seem to lend probability not only to such conjectures, but to others which are now to follow.
We have imagined ourselves watching on Mars the progress of the life-giving water spreading from the south pole during the spring and early summer of that hemisphere of the planet. But we have noticed its effects only in the great depressed regions that may once have been actual seas. How about the still greater regions which nobody has ever supposed to be seas, and which appear on the charts of Schiaparelli and others under the name of continents? If Mars has not water enough to keep its sea-beds permanently covered, its dry lands must thirst indeed! Let us go, then, to that strange region where lies the so-called "Lake of the Sun."
As we cross the red continents, hot and blazing in the merciless sunshine, we begin to meet the "canals," but, behold! they are not canals! They are broad streaks or belts of vegetation, intersected with numerous tiny water-channels, like the valley of the river Po or the flat meadows of Holland, and the water comes from the vast swamps formed, as we saw, by the polar inundation.
Now our interest rises to the dramatic pitch, for here is the work of hands, here are evidences of intelligent design, and here, if anywhere on this distant world, we must expect to meet its inhabitants. I shall not undertake at this point to describe the appearance that those inhabitants might present. But let us imagine that we put ourselves under their guidance.
It is probable, for a reason which I shall mention presently, that our Martian friends would turn out to be exceptionally intelligent. They might guess, then, that we would have a rather poor opinion of their world of floods and deserts, and for that reason they would lead us at once to its finest scenes. Through the corn-land and the vine-land of their irrigated belts, traversing the sandy wastes with strips of green, they would doubtless conduct us along magnificent shady roads to one of the numerous crossing-places where two or more of the fertile bands meet, and where our astronomers on the earth have noticed that there is always an oval dark spot, which some of them have thought must mark the site of a lake.
