LABORATORY EXERCISES 



As part of the practice to accompany this chapter a ginnery 

 should be visited, and inspection made of the parts of some gin 

 while it is not in motion. 



While it is not advisable for instruction in cotton classing to 

 be given by any except experts of long experience in cotton 

 buying and classing, it may be possible for sam.ples of middling 

 cotton to be procured by the school and for the pupils to become 

 somewhat familiar with its characteristics. 



College classes will doubtless be instructed by an expert, who 

 will need a complete set of specimens, or types, which can usually 

 be purchased from the U. S. Department of Agriculture.
