Chicago, September 8, 1901
I have yours of 6th.
The custom is to keep the room lighted while the speaker makes his introductory remarks, and then to turn the lights out when the pictures are to be shown, leaving a shaded light for the speaker to read by. Diagrams can be used during the introductory, or photographed to throw upon the screen during the illustrated part. The meetings are informal and the members attend in business dress. We will conform to your wishes in not making your address unduly prominent, and will decide as to the presence of ladies after canvassing the probable attendance. We generally have 50 to 75 members present.
Let me know which of my photos you want reproduced. I suggest 1, 2, 4, 5, & 12; also possibly 6.
