The Earth-monster had not yet seen us; and at this juncture I took the opportunity to hastily scribble some notes which I very shortly regretted. However, to illustrate the fact that anyone may make mistakes and that even the most apparent truths may be misinterpreted, I will here reproduce what I wrote: "The intelligent inhabitants of Earth somewhat resemble us in the possession of four limbs, two eyes, and two elongated protuberances which are very likely ears.

At any rate, it suddenly turned toward us, displaying an expressionless metal face with a curious grille arrangement in front; and,
