The following  presentation was created from a 35mm slide/cassette tape program by Carl W. Nichols shown at the 58th Annual National Plant Board Meeting held in Cherry Hill, New Jersey on August 15, 1984. The slide show and tape, now held in the archives of the Kansas Historical Society were duplicated in order to prepare this version of Carl's show. The original slides apparently were taken with a handheld camera, thus many are not square with the frame. The accompanying audio tape also had some distortion that can be heard in parts of the presentation, especially at the beginning, as a result of years of storage on the cassette. Carl used a chime to indicate that the next slide should be advanced and is retained in this version for the same purpose.
This program runs for about 30 minutes. Audio files are large (100-300K each),  thus this program may not be suitable for viewing over a dial-up connection.
