“If vegetation exists on Mars, as Prof. Lowell would have us believe that, the existence of a flora is floor for suspecting a fauna. On Mars we find ourselves confronted in the canals and oases by exactly the appearance which the world really should present if it is an inhabited earth. Dearth of h2o is the critical to the character of the canals. The only readily available h2o on Mars is that coming from the semi-annual melting at the just one or the other cap of snow. If there are intelligent beings on Mars, they ought to find some usually means of conducting the scant offer of h2o from the poles to the centers of populations.”
—Scientific American, July 1907
