LABORATORY WORK 251 



finished descriptions be kept in the student's 

 note-book. They may be written first on 

 temporary sheets, corrected, and afterward 

 copied to permanent sheets for filing, or 

 directly into the note-book, if the instructor 

 sees fit. 



2. After the student has had a fairly good 

 drill in the description of apples, he should 

 pass to other fruits. The ideal order would 

 be apple, pear, quince, plum, peach, cherry, 

 grape, raspberry, and strawberry ; but these 

 fruits can never be secured fresh from the 

 fields in this order. The exigencies of the 

 season will determine very largely what the 

 order shall be. Before this part of the work 

 is closed, however, the students should be 

 very thoroughly drilled in the description of 

 all the standard fruits which can be had in a 

 fresh state direct from the trees or vines. 



3. The student is now prepared to go to 

 the field to study the trees and vines for their 

 systematic characters. He has now on hand 

 a number of descriptions of fruits; let him 

 complete these by adding descriptions of the 

 plants from which the fruits came. This 

 should always be done, if possible, at the sea- 

 son when fruit is maturing, for a fruiting tree
