do better and some worse grafted than when on their own roots. Nearly 
all plums improve in all respects by grafting and generally improve with 
age for several years, even on their own roots. He showed us a number 
of plum trees that had two or three hundred different seedlings grafted on 
them and one apple tree that he said was grafted with 526 different seedlings. 
The experiment grounds at Sebastapol are laid out in a very neat and 
systematic way. He uses no irrigation, as the rainfall in this part of Cali- 
fornia is plentiful and well distributed through the growing season.

In his first catalogue Mr. Burbank uses the following words: “There 
is no possible room for doubt that every form of plant life existing on the 
earth is now being, and has always been, modified more or less by its sur- 
roundings, and often rapidly and permanently changed, never to return 
to the same form. When man takes advantage of these facts and changes 
all the conditions, giving abundance of room for expansion and growth, 
extra cultivation and superabundance of the various chemical agents in 
the most assimilable form, with abundance of light and heat, great changes 
sooner or later occur, according to the susceptibility of the subject; and 
when added to all these combined governing forces we employ the other 
patent forces of combination and the selection of best combinations, the 
power to improve our useful-and ornamental plants is limitless.” 
“Tomatoes may be grown from seed pollenated by potato pollen only; 
pure wheat from rye pollenations, and vice versa. Pure raspberries, black- 
berries and dewberries from apple, rose, quince or mountain ash pollena- 
tions. 
“There is no barrier to obtaining fruits of any size, form or flavor de- 
sired, and none to producing plants of any form, color or fragrance; all 
that is needed is a knowledge to guide our efforts in the right direction, 
undeviating patience and cultivated eyes to detect variations of value.”
