Changes in the size, shape, arrangement, and replication of small plats have necessitated changes in the methods used in the planting, harvesting, and threshing of the grain grown on such plats. Features of five machines now in use on the plant breeding plats at East Lansing and developed under a cooperative project between the sections of Farm Crops and Agricultural Engineering of the Michigan Agricultural Experiment Station are discussed in this article with the hope that they may be helpful to other workers. Whenever a change has been made, it has been judged on the basis of (1) maintenance of purity, that is, freedom from mechanical mixture; (2) simplicity of operation; (3) efficient use of man power; (4) simplicity of construction; and (5) increase in speed of operation. The first requirement is the most essential and its importance is recognized by all. The other requirements are making themselves felt more and more as experiments are becoming more extensive and refined and expense is becoming more of a factor in planting, harvesting, and threshing.
