PERMANENT LABELS 



These labels are important time- 

 savers. Each set of holes represents 

 a specific plant or a different type of 

 experiment, the key to the labels being 

 found in the record books. The lower 

 right hand label here shown might indi- 

 cate, for example, that the branch on 

 which it is tied bears blossoms of 

 the Sugar Prune {one hole at base of 

 label) , fertilized by pollen of the Con- 

 quest stoneless prune (two holes near 

 center of label). Such labels as these 

 are loosely attached to the stem of the 

 plant that has been pollenized or 

 grafted. They are reasonably per- 

 manent, and minimize mistakes.
