5. The great damage from Talight in the Valley comes 
primarily from the fact that it gets into the 'body of the 
tree, either completely girdling the trunk and killing it, 
or so greatly reducing vitality as to make the fruit of 
little value. The lalight does not stop at the "body tut 
frequently runs down and destroys the root as well. In 
many orchards, all of full hearing age, ahout one tree in 
five shows these trunk and fruit injuries. A good many 
trees have heen killed and taken out. 
6. Blight occurs in the tops hut that is a com- 
paratively simply matter, and can, according to Mr. Reimer, 
he easily controlled. 
7. If pear growing is to continue in this valley and 
on the coast, the industry must he hased on the varieties 
now firown . The problem, therefore, is to find a sub- 
structure for the top, which will give a long lived, healthy 
tree; which will adapt itself to a variety of soils and 
climates; which will he blight proof; which will withstand 
woolly aphis and other insects; which may be horti culturally 
handled in a practical way; and which may support the half 
dozen or more standard varieties now commanding this market. 
8. It is not expected that any one stock will do this. 
There will need to be a number and from this number many 
combinations may be secured. In short, Reimer is opening 
up the very large and important question of the relation 
December 31, 1916.
