RECORDING EXPERIMENTS 49 



An exact record must be kept of these items, 

 and for this purpose a book with removable un- 

 ruled leaves is the mcst satisfactory. 



The fruit should be cut in half with a sharp 

 knife. The incised surface may then be placed 

 directly on the paper, and the outline of the fruit 

 traced with pencil. The specimen may similarly 

 be outlined in cross section. This preserves a 

 graphic record of the exact size and form of 

 the fruit. The main character of the inside of 

 each fruit may be indicated, and by adding the 

 date of ripening, the time of its earliest and me- 

 dium ripening, the number of days it will re- 

 main in good condition upon the tree, its keeping 

 quality when packed for shipment, and its sus- 

 ceptibility to the ravages of insect pests and 

 fungoid disease, we have on a single sheet a 

 fairly complete and very valuable record, to- 

 gether with a graphic representation of the form 

 and size of the fruit itself. 



Record will be made in the same way in suc- 

 cessive seasons of fruit from the same tree, with 

 additional record of the appearance of any new 

 characters or qualities. Comparison of the rec- 

 ords will show whether the fruit on the young 

 trees has increased in size, improved in quality, 

 or varied in time of ripening from year to year. 

 Not unfrequently the record of the third year
