 not larger in appearance than about 19′, less than two-thirds that of the Sun; and she consequently appeared as a black disc covering somewhat more than one-third of his entire surface, but by no means concentrical. The halo had of course completely disappeared; but with the vernier it was possible to discern a narrow band or line of hazy grey around the black limb of the planet. She was moving, as seen from the Astronaut, very slightly to the north, and more decidedly, though very slowly, to the eastward; the one motion due to my deliberately chosen direction in space, the other to the fact that as my orbit enlarged I was falling, though as yet slowly, behind her. The sun now shone through, the various windows, and, reflected from the walls, maintained a continuous daylight within the Astronaut, as well diffused as by the atmosphere of Earth, strangely contrasting the star-spangled darkness outside.

At the beginning as at the end of my voyage, I steered a distinct course, governed by considerations quite different from those which controlled the main direction of my voyage. Thus far I had simply risen straight from the Earth in a direction somewhat to the southward, but on the whole "in opposition," or right away from the Sun. So, at the conclusion of my journey, I should have to devote some days to a gradual descent upon Mars, exactly reversing the process of my ascent from the Earth. But between these two periods I had comparatively little to do with either planet, my course being governed by the Sun, and its direction and rate being uniform. I wished to reach Mars at the moment of opposition, and during the whole of the journey to keep the Earth between
