May 31. Saw a little more than I saw last night but did not see a trace of things that Mr. Lowell and his assistants apparently saw without effort. I realize that it requires a special training to observe the flickering evanescent markings on Mars. June 1. Though the best night yet for steady atmosphere I saw but little more and have come to the conclusion that it will take months of continuous observation before I can see anything. June 2. I went to the Observatory to-night in despair of ever seeing anything more. Got into the observing chair and immediately saw a number of markings I had not seen before, as my drawings show. I have purposely refrained from studying the maps, and so do not know the names of the lines detected. June 3. Atmosphere so unsteady that it was impossible to make anything out of Mars, so after struggling awhile gave it up in disgust. June 4. Seeing about 4, yet manage to see a few planetary details. June 5. I find a slow advance in my ability to see the markings though it is exasperating that the janitor of the Observatory talks about plainly seeing certain details which he indicates to me by a sketch, and looking at the region I can see no trace of a canal or anything else. June 7. Seeing very good and in my observations tonight added another canal. It is a most difficult matter to catch the fleeting lines as they appear with startling distinctness to instantly vanish again. June 9. Seeing fairly good. Could make out but little more. Color of regions very strong and vivid. June 10. Seeing a little better than last night. Added three new canals, and these canals flashed out three or four times before I was willing to record them, and then I did not believe them till Mr. Lowell showed me a drawing he had made just before, and the two drawings corresponded. June 11. Looked at eight o'clock and the markings of larger features came out strong and dark and yet the seeing was not estimated high. June 12. Rather poor seeing though some of the dark regions came out with remarkable distinctness. Every day I notice a very slight improvement in detecting lines. Markings formerly made out with great difficulty are now instantly recognized. June 13. In my observations to-night added one new canal and completed another, and was able to detect one that Mr. Lowell had not seen during the evening--a well-known one he says. It simply shows that one must continually observe as the lines flash out for a single instant.
