frequency may be regulated according to the 

 abundance and the persistence of the enemy. 



All in all, it is a severe gauntlet that the little 

 seedling is called upon to pass. Yet if the 

 methods described in this chapter are carefully 

 followed out, it is possible to grow successfully 

 any seed, from whatever climate or soil or loca- 

 tion, that has the least germ of life within it. 



These methods have been successfully used 

 with the seeds I am constantly receiving from 

 numerous collectors in Siberia, Brazil, Chile, Ar- 

 gentina, Patagonia, Mexico, Central America, 

 the Philippine Islands, Alaska, British Columbia, 

 north and south Africa, Europe, India, South 

 Sea Islands, Australia, New Zealand, central and 

 western China, Japan, and Korea. 



By sedulous attention to the details above out- 

 lined, the raising of seedlings becomes so certain 

 a procedure that the loss should not exceed one 

 plant in a thousand. And this, obviously, is a 

 most important consideration, especially with rare 

 foreign seeds or seeds produced by hybridizing 

 experiments that have involved exceptional care 

 and labor. To such priceless stock, any amount 

 of time and labor may be given ungrudgingly. 

 And even in planting common nursery stock one 

 soon learns that a thorough knowledge of the re- 

 quirements of the plants is essential to success.
