Chicago, August 23, 1901
I have your welcome letter of 22d and am glad to know that you got through your experiments without accident. I think you have performed quite an achievement in sailing with surfaces wider than any which I dared to use, and on which a change of incidence by a wind gust would make so great a difference in the center of pressure.
I send you a full set of all the photographs taken by my camera. Most of them are failures from various causes. They are numbered on the back. If you will say which you want, I will either have them printed for you or send you the films.
Also let me know what to remit a/c expenses.
