on regard it as uninhabitable. He endeavoured first to ascertain
the extremes of temperature to which we earth beings were exposed, and he
was deeply interested by my descriptive treatment of clouds and rain. His
imagination was assisted by the fact that the lunar atmosphere in the
outer galleries of the night side is not infrequently very foggy. He
seemed inclined to marvel that we did not find the sunlight too intense
for our eyes, and was interested in my attempt to explain that the sky was
tempered to a bluish colour through the refraction of the air, though I
doubt if he clearly understood that. I explained how the iris of the human
eyes can contract the pupil and save the delicate internal structure from
the excess of sunlight, and was allowed to approach within a few feet of
the Presence in order that this structure might be seen. This led to a
comparison of the lunar and terrestrial eyes. The former is not only
excessively sensitive to such light as men can see, but it can also _see_
heat, and every difference in temperature within the moon renders objects
visible to it.

"The iris was quite a new organ to the Grand Lunar. For a time he amused
himself by flashing his rays into my face and watching my pupils contract.
As a consequence, I was dazzled and blinded for some little time....

"But in spite of that discomfort I found something reassuring by
insensible degrees in the rationality of this business of question and
answer. I could shut my eyes, think of my answer, and almost forget that
the the Grand Lunar has no face....

"When I had descended again to my proper place the Grand Lunar asked how
we sheltered ourselves from heat and storms, and I expounded to him the
arts of building and furnishing. Here we wandered into misunderstandings
and cross-purposes, due largely, I must admit, to the looseness of my
expressions. For a long time I had great difficulty in making him
understand the nature of a house. To him and his attendant Selenites it
seemed, no doubt, the most whimsical thing in the world that men should
build houses when they might descend into excavations, and an additional
complication was introduced by the attempt I made to explain that men had
originally begun their homes in caves, and that they were now taking their
railways and many establishments beneath the surface. Here I think a
desire for intellectual completeness betrayed me. There was also a
considerable tangle due to an equally unwise
