136 HEARINGS BEFORE COMMITTEE ON AGRICULTURE. 
izers which were believed to be cures for yellows, and our first exper- 
imentation was in that direction, to determine whether or not they 
had any effect in that direction. It was finally determined that they 
had no effect whatever in curing or preventing the yellows, and as 
a result of that you never hear ae more about the application of 
fertilizers. The money spent in that direction has been turned into 
other fields. 
One other line of work has been set aside, and that is the subject of 
grape diseases. They have reached the point of treatment so that it 
does not require any great effort to control grape diseases. When we 
first commenced to spray for grape diseases we had to pay a bonus to 
people-to spray. The first money was spent that way in different 
parts of the country. The next year we had three or four volunteers 
and the fourth and fifth years we had between 6,000 and 8,000 volun- 
teers. So that work developed to a point where it can be dropped, 
and the spraying of grapes now is a matter like the application of 
fertilizer. 
Mr. Woops. Then there is the subject of the various blights that 
we have not worked on for a number of years. 
The CHairman. That spraying was a great discovery. 
Mr. Woops. Yes, sir. There are diseases of other crops that we 
have been working on and which were finished a number of years ago 
that we have not even thought of since that could be outlined in the 
same way that I have outlined these works. 
The Cuarrman. Doctor, in your note of the list of people paid from 
the lump sum on that same page (p. 9) I see one pathologist at 
$3,000. I notice that is a higher salary than the pathologist who is on 
the statutory roll. 
Mr. Gattoway. Yes; that is the salary of Mr. Woods, who is in 
charge te the work, and then we have one for $2,750 on the statu- 
tory roll. 
Mr. Woops. That is Doctor Smith, in charge of the pathological 
laboratory. 
The CuarrMan. Are not some of those gentlemen permanent in that 
way, so you could put them on the statutory roll? 
Mr. Gatioway. Yes, some of them are; but that question we have 
had up here before. It is a question whether it is economy to put 
them there, because it puts us in a position where we are in the posi- 
tion of paying more than we really ought to pay. That is the position 
of some of the other bureaus of the Government. 
The Cuatrman. ‘‘One expert at $600.” What is he expert of? 
Mr. Woops. There are two experts there—one is Professor Hayes, 
who is in charge of the cooperative work in these five States I men- 
tioned. He is the professor of agriculture in Minnesota. 
The Cuairman. This is an additional salary paid him? 
Mr. Woops. Yes, sir; and the otherone is Florence Eddy. Sincethis 
roll was made out she has taken an examination and has been appointed 
assistant of bacteria in the State physiological laboratory. 
The Cuarrman. Two experts at $1,500, which you will see on the 
fourth line. 
Mr. Woops. One of them was one of the men in the physiological 
laboratory who has been working on some of the physiological prob- 
lems, Doctor McKenney, and the other is the one who is working 
on physiological chemistry in grains and plants. Both of those have 
taken the civil-service examination and their titles are now changed.
