Excerpt from book: CHAPTER VII. The Present Evolutionary Period of Mars. The important features of this planet are its relative distance from the Sun (141,500,000 miles), about one and one-half times the distance of the Earth from the solar body: its seasonal polar caps: and its canals, also seasonal, stretching from the summer pole beyond the equator, and well towards the winter pole. The volume of Mars is one-seventh that of the Earth, and its density is calculated as seven-tenths that of the Earth. In as much as the planet is further from the Sun than the Earth so it is behind in evolutionary period. Mars is probably at that period corresponding to the arcluean age of the Earth when the primary or Lau- rentian system of rocks was formed. A difference of opinion exists among observers as to there being water on Mars. Spectra of planets must vary according to their positions relative to the Sun and the Earth. Mars in conjunction and in opposition will reflect solar light from the hemisphere proximate to the Sun, where his atmosphere will contain little or no water. In quadrature, especially if the planet's winter pole can be viewed, is the most favorable position to get the spectrum of water. Mars has but one water cycle: From surface water to the cloud, H20, thence to the winter pole where it manifests as a snow or ice cap, 11262, thence from the same, now summer pole, through the canals toward the then winter pole. Thus Mars is tearing up his polar unstratified rocks and forming Laurentian stratifications. The snow caps at the poles of Mars enlarge during their respective winters and become smaller or entirely disappear during their summers. It seems that in the water cycle of Mars the water-vapor in the atmosphere and the water-liquid in canals seek the pole of the planet furthest f...
