June 14. Made out still another canal to-night. The markings show very clear, in fact some parts were vivid in distinctness and the lower part of Syrtis Major dark blue. June 15. Poor seeing, yet I was able to see a few of the prominent features and defined the wedge-shaped region below. On Plate IX I give a few of my drawings of Mars in which are indicated the lines I saw many times and was able to fix. Other lines flashed out for an instant but these were not recorded, simply because I could not definitely locate them.

Poor seeing, therefore, at Flagstaff would be equal, if not superior, to the best seeing at much lower levels. An astronomer who resigned his position in a western observatory for duties at Mount Wilson, California, told me that for thirty consecutive nights the seeing was superior to the best nights he had observed in at his former post. XV WHAT THE MARTIANS MIGHT SAY OF US _O wad some power the giftie gie us, To see oursels as others see us!_ ROBERT BURNS. For every single perplexity of interpretation we encounter in our study of the surface markings of Mars, the Martian would encounter a dozen perplexities in interpreting the various features on the surface of the Earth. Admitting the conclusions of Lowell of the existence of intelligence in Mars, and that that intelligence has been associated for ages with a planet having only slight elevations of land, a tenuous atmosphere, a scarcity of water which has been utilized for ages through artificial channels, as we have done in various parts of the world since prehistoric times, having vast tracts of sterile plains, and, within these sterile tracts large oases fed by irrigating canals, regions of sparse vegetation, and no large bodies of water; with these conditions going beyond the history of these intelligences, what must be the Martian interpretation of the surface features of this world? It is a perfectly fair inquiry, for by such means we may appreciate the attitude of some of our interpreters of Mars.
