Material which had accumulated on the inner surface of gin roll boxes during the ginning of immature bolls has been collected and subjected to chemical analysis. This deposit material, which was a dried, hard, dark-brown substance, has been shown to be about 25% protein and 8% lipid, the remainder being fuzz fibers, lint, and seed-coat fragments. The protein had an amino acid composition similar to the protein of cottonseed and the lipid was composed of cotton wax and cottonseed oil. It was suggested that the deposit material originates from immature cottonseed and it may be the same as material that causes saw tooth clogging, which can occur when early season machine-stripped cotton is ginned.
