RECORDING THE EXPERIMENTS 



later in the season when the seed is to be gathered; 

 because they make known at a glance the facts as 

 to parentage, and make it possible to keep sepa- 

 rate the seeds of different varieties. The labels 

 are tied to the plants with common twine, as wire 

 or other hard substances would be likely to injure 

 the tender stems when the wind moves the tags 

 about. 



When numerous varieties of plants are grown 

 in a single bed, we often nail a common tree label 

 opposite each row on the board that borders the 

 bed, instead of using a stake, as there is less danger 

 of the label being displaced. It will be advan- 

 tageous to place this label at the side of the bed 

 away from that from which the prevailing winds 

 and storms come. In this section of California 

 the summer winds and winter storms come from 

 the South, East, and Southwest, and in conjunction 

 with the hot sunshine, they are very destructive 

 to paint. So it is advantageous to face the labels 

 toward the North. 



All of these are matters of minor detail, yet not 

 without their importance. 



Recording Results 



In making selection of individual plants that 

 are to be preserved, or from which seed is to be 

 gathered, the most convenient, and at the same 

 time the most accurate method is the simple one
