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.
