th;it a great many other trees that h;id not begun to show it, 

 ^^■ould soon do so. It was one of the things that, if I had 

 been a grower there, would have worried nie, because it is one 

 of those things affected by the soil conditions, and far more 

 viifficult and serious to handle than a trouble which attacks 

 the leaves or In-anches. 



A third difficulty which was very common was the 

 aphis. I was rather surprised to see how general it was 

 out there. You would find trees in almost every orchard 

 that were afl'eeted, and as far as I saw them, fully as gen- 

 eral in those well-kept orchards as we have in our ^lassa- 

 chusetts orchards which are not so well kept. It was 

 apparently one of the most serious orchard pests at the 

 present time. • 



Another thing very closely associated Avas the woolly 

 aphis. This was becoming very common in some sections. 

 -\ good many trees in Hood River were attacked, more 

 particularly on the water sprouts. [ was talking to one of 

 the men who has charge of the local experimental station 

 and he said that he considered it one of the most serious 

 things they had to contend with for several reasons. 



First, because it was an insect that was hard to kill by 

 spraying; second, because the materials which were neces- 

 sary were relatively very costly; and third, because the 

 spraying for it came at a time when growers were tired out 

 with their spraying for other pests. He was afraid he said, 

 that they were going to have very serious trouble in con- 

 trolling it. 



Another troul)le. and one which they nearly all consid- 

 tred as their most serious one, was tire blight. Of course, 

 we have that here more or less and know something about 

 it. but nothing to compare with what they have out there. 

 However, in two or three sections (in ]\Iedford, Oregon, for 

 ■nstance). they have it under control so thoroughly that 

 they do not consider it is a seriovis matter. 



I was told by one of the inspectors there that tliey con- 

 sidered they had solved that question, that if their growers
