 After I had eaten I was greatly invigorated, but feeling the need of rest I stretched out upon the silks and was soon asleep. I must have slept several hours, as it was dark when I awoke, and I was very cold. I noticed that someone had thrown a fur over me, but it had become partially dislodged and in the darkness I could not see to replace it. Suddenly a hand reached out and pulled the fur over me, shortly afterwards adding another to my covering. 

 I presumed that my watchful guardian was Sola, nor was I wrong. This girl alone, among all the green Martians with whom I came in contact, disclosed characteristics of sympathy, kindliness, and affection; her ministrations to my bodily wants were unfailing, and her solicitous care saved me from much suffering and many hardships. 

 As I was to learn, the Martian nights are extremely cold, and as there is practically no twilight or dawn, the changes in temperature are sudden and most uncomfortable, as are the transitions from brilliant daylight to darkness. The nights are either brilliantly illumined or very dark, for if neither of the two moons of Mars happen to be in the sky almost total darkness results, since the lack of atmosphere, or, rather, the very thin atmosphere, fails to diffuse the starlight to any great extent; on the other hand, if both of the moons are in the heavens at night the surface of the ground is brightly illuminated. 

 Both of Mars’ moons are vastly nearer her than is our moon to Earth; the nearer moon being but about five thousand miles distant, while the further is but little more than fourteen thousand miles away, against the nearly one-quarter million miles which separate us from our moon. The nearer moon of Mars makes a complete revolution around the planet in a little over seven and one-half hours, so that she may be seen hurtling through the sky like some huge meteor two or three times each night, revealing all her phases during each transit of the heavens. 

 The further moon revolves about Mars in something over thirty and one-quarter hours, and with her sister satellite makes a nocturnal Martian scene one of splendid and weird grandeur. And it is well that nature has so graciously and abundantly lighted the Martian night, for the green men of Mars, being a nomadic race without high intellectual development, have but crude means for artificial lighting; depending principally upon torches, a kind of candle, and a peculiar oil lamp which generates a gas and burns without
