Flagstaff that the
existence of water vapour on Mars is demonstrated by the photographic
spectrum of the Martian atmosphere; and he asserts that the attempt to
disprove it has failed. A further discovery has since been made at the
same observatory, viz. that oxygen also is present in the atmosphere of
Mars!

During the observations in 1909 several observers noted that, at times,
very large areas on the surface of Mars had been so obscured by a
yellowish veiling that all details were entirely blotted out. The
announcement of this fact gave rise to sensational statements that a
terrible catastrophe had occurred on the planet. The explanation is,
however, very simple--seasonal mists arising from the canals, with the
addition of clouds of sand particles in the upper air, as the result of
desert sandstorms, caused a temporary obscuration of certain parts of
the planet as viewed from the earth. Only this, and nothing more!

We have been interested to note that an English observer, the Rev.
Theodore E.R. Phillips, has observed some new details on Mars in the
region where the new canals were discovered. Mr. Phillips has in past
years given considerable attention to this region, and observed several
changes in the Lacus Moeris, to the east of Syrtis Major. The lake
disappeared altogether for some considerable time, then reappeared. Last
September he saw it again, and it was evident some further changes had
occurred; and he also saw some dusky shadings on the adjacent desert of
Lybia. There seems little doubt but that he actually saw, though
imperfectly, the new canals which Professor Lowell's much clearer
atmosphere and larger instrument enabled him to see clearly.

From what has been related in the last few pages it will be seen that
many of the forecasts, as set forth in this book by our old friend the
Professor, and his statements as to the Martians being actively engaged
in altering, extending, and developing their canal system, have been
amply verified by the observations of our astronomers; and I am
confident that his other prognostications will also be fulfilled in
course of time.

Turning now from scientific matters to others affecting ourselves
personally, I may say that I have heard nothing more of my cousins the
Snayleyes; and, after the failure of their mean attempt upon my liberty
and fortune, it is not likely that I shall again be troubled by them,
for they will naturally take good care to keep out of my way.
