But before that, I must needs allow myself just one parting glance at our cross-electric protective panoply. It surrounds us like a light but mysterious auroral mist, to protect from meteorite impact and from other space-filling dangers our slight and fragile craft. All seeming in order there, imparting a comfortable security, I take, ere turning in, just one last fond look of our retreating earth, already dwarfed by half a million miles interval, and already also somewhat out of line with our direction, through the progress meanwhile in her own orbit, as she rolls everlastingly along her grand circumsolar highway.
