now has come their crucial test: each one 
must pass in review before the eye of their 
master. 
In the ordinary course of plant-breeding 
each one of these hundred thousand plants 
would need to be grafted, or budded, each one 
would need individual care. It would require 
at least five years before the final test would 
come and a showing be made of the value, or 
the worthlessness, of each particular tree. 
While no such test in a single experiment has 
ever been made, it may be stated in general 
terms that to graft and carry through to the 
end of the five-year period a hundred thousand 
trees would involve an outlay in actual money, 
and in rental value of the large area of ground 
necessary at least ten dollars per tree—a total 
of one million dollars. 
This is saved by Mr. Burbank in one work-

is best expressed by the term intuition. 
With assistants to bring and carry away the 
tiny slender trees, perhaps now grown to a 
height of one to three feet, he passes upon the 
hundred thousand in a single day, going over 
them with lightning-like rapidity, challenging
