Plant-Breeding for Farmers. 143 



Should the selection be continued longer than about six years these 

 numbers will become cumbersome and in this case new numbers can be 

 given to all selections made in any year, numbering them again i, 2, 3, 

 and upward. Under each of these a reccrd can be made of the row from 

 which it was taken, which will connect it with the preceding records ; thus, 

 No. I (from row 2-1-3-5-2-4) etc. 



With reference to keeping the notes the following is a suggestion of ar- 

 rangement through three years :
