    The planet mars and its inhabitants 

    Urides, Eros

    One hemisphere of Mars showing the North Polar Cap and the main Canal System covering the planet. The many thousands of small lateral canals, radiating from the larger waterways, and which form an important part of the general plan, have been purposely omitted from the above to avoid confusion. The circular spots and dots are the principal reservoirs used for impounding water for use during the long Martian summer. Tomado del texto original Fecha de reseña: 27/06/2016
