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.

As the days and weeks pa.s.s by I often think of those we left behind upon that far distant world: wondering how they are faring, and whether they have attempted to transmit any influences or communications to us, for up to the present we have not been conscious of any such influences.

Kenneth M'Allister is a thoroughly happy man, as he is working for his own benefit, congenially and fully occupied with matters connected with his beloved machinery. He is on the high road to making a very large fortune; indeed, we are both doing remarkably well, and are, therefore, able to give financial aid to many projects in which we are interested, having for their objects the uplifting of the people, and the improvement of social conditions generally. It was only yesterday that M'Allister remarked to me, "Heh, mon, if we continue to go ahead at the same rate as we are going now, we shall both be millionaires before very long!"

Yes, we are doing well--there is no doubt about that; but, notwithstanding my present very satisfactory circ.u.mstances and the certainty of a brilliant future if I stay here, ideas have long and persistently been running in my mind that it would be far better for me to go back to Mars, and--by Jove! strange indeed that I never thought of it before!--perhaps those very persistent ideas are actually the outcome of Martian influences!!

The wonderful music I heard upon Mars still rings in my ears; and, at times, so thrilling and peculiar is its effect upon me, that I feel as though I were being almost irresistibly impelled to return to that planet. Well, I should very much like to see the dear old Professor and Merna again, and also my many Martian friends. Then there's Siloni, whom I can never forget, for mentally her image is ever before me. What a nice girl she was! If I were to return to Mars, I wonder whether----?

FOOTNOTES:

[1] The exact diameters of the planets are difficult to measure owing to irradiation, and estimates of various authorities differ, especially with regard to the more distant planets.

[2] Most probably the larger planets possess satellites which have yet to be discovered.

[3] It is not yet ascertained with certainty whether Mercury and Venus rotate in about twenty-four hours, or whether the period is the same as that of their revolution round the sun. The evidence seems to point to the latter period.

[4] The "terminator" is the boundary between the lighted and the dark portion of the disc.

[5] Those who have seen the undercliff in the Isle of Wight will be able to form some idea of the terraces of the lunar ring-mountains, as they are very similar formations.

[6] This is the case as regards separate satellites; but it may be pointed out that a similar thing must occur in regard to the rings of Saturn. The rings are composed of swarms of satellites so small that they can only be termed particles, and these particles at the inner edge of the "c.r.a.pe ring" revolve round Saturn in 5 hours and 33 minutes, the inner edge of the ring being only about 47,000 miles from the centre of the planet. The planet itself revolves on its axis in 10-1/4 hours.

Thus, an immense number of these minute satellites must revolve round the planet in less time than it takes the planet to make one rotation.

It is calculated that the particles in the outer edge of the next ring complete one revolution round the planet in 14 hours and 28 seconds.
