As we compare the circular markings on the Moon with our terrestrial craters and fissures, and cracks on its surface with similar fissures on the Earth, so we are forced to compare the markings on the surface of Mars with what seems analogous to them on the surface of our own Earth.
Once proved that the markings of Mars are due to erosion, cracks, encircling meteors big enough to raise ridges by their attractive force, then all that has been written in demonstration of their artificial character goes for naught. The intelligent reader unprejudiced in the matter will, however, judge for himself the merits of our contention and will determine the reasonableness of the comparisons that have been made by Lowell in solving the mystery of Mars.

[FOOTNOTES]
[1] Some of our readers may not know that light travels, in round numbers, at the rate of 186,000 miles a second.
[2] The terminator represents the limit of light on that side of the planet in the shade, in other words, where the light terminates. In viewing the Moon, when at quarter or half, the terminator is seen very ragged on account of the illumination of higher points on the surface. If the Moon was as smooth as a billiard ball the terminator would be clear cut.
[3] The world in its ignorance of Italian assumed that the word meant exclusively canals, and, if canals, then dug by shovels. What! a canal thirty miles wide and two thousand miles long dug in the snap of the finger? Impossible conception, you say. We shall see later the sober utterances of a member of the British Astronomical Society on this gratuitous assumption, and an equally serious comment by the chief assistant of the Royal Observatory at Greenwich (E. S. M.).
