 is best to have a few new varieties on hand 

 every day, and to give the class an exercise of 

 this sort when they first enter the laboratory, 

 after which they may proceed to the regular 

 work of the day.

 samples should be mixed indiscriminately in a 

 basket or on a table, and the students required 

 to separate and name them. The task of 

 sorting out closely related varieties will be

 effort, to come within reach of one or two 

 general fruit exhibits. During the fall these 

 can be found in connection with county, dis-
