SELECTIVE EVOLUTION 225 



But if we graft out at the tip ends, we can put 

 ^ye hundred or more cions on a single tree. 



By grafting the smaller branches, fruit pro- 

 duction is greatly hastened, cutting from two to 

 seven years out of the long wait for the fruit 

 which is to tell the story of the heredities which 

 are confined within the seed. 



It is possible, at this point, to give but the 

 barest glimpse of the results which this mode 

 of grafting made possible. Under the proper 

 heading, the details will be fully explained, to- 

 gether with a summary of the results of hun- 

 dreds of thousands of grafts, showing that, while 

 the average time of fruiting has been brought 

 down to less than two seasons, in some excep- 

 tional cases fruit has been secured for testing 

 the same season that the graft was made. 



Here, too, it is not possible to convey more 

 than a general idea of the plans which, in every 

 operation, are aimed toward the end of produc- 

 ing the quickest possible test. Whether it be the 

 quince seedlings bearing fruit the first year or 

 yearling chestnut trees loaded down with nuts; 

 or ten year old walnut trees, the size of their 

 century old cousins — all through this work 

 the plan and the method is to save time for the 

 individual plant as well as to provide short cuts 

 for the process of evolution.
