Lowell, Percival: Mars (Illustrated), v1 1 Sep 2008
From the Preface:
This book is the result of a special study of the planet made during the last opposition, at an observatory put up for the purpose of getting as good air as practicable, at Flagstaff, Arizona. A steady atmosphere is essential to the study of planetary detail: size of instrument being a very secondary matter. A large instrument in poor air will not begin to show what a smaller one in good air will. When this is recognized, as it eventually will be, it will become the fashion to put up observatories where they may see rather than be seen.
Next to atmosphere comes systematic study. Of the extent to which this was realized at Flagstaff, I need only say that the planet was observed there from May 24, 1894, to April 3, 1895, during which time, to mention nothing else, 917 drawings and sketches were made of it. Prof. W. H. Pickering and Mr. A. E. Douglass were associated with me in the observations herein described.
Such as care to see the original data more technically and minutely treated will find them in the first volume of the Annals of this observatory.

Wonderful! It's perhaps worth saying, for those unaware of it, that Lowell was the champion of the idea that Mars had "canals", built by intelligent beings to preserve a dwindling water supply, and that the illustrations in this book helped to popularise that idea.
