HEARINGS BEFORE COMMITTEE ON AGRICULTURE. 101 
duction, but after we develop a good strain and show that it can be 
grown commercially, another group of men then take it and put it 
into commercial use. 
For the work on root rot of cotton and alfalfa we are now expending 
about $3,000. We have one man and an assistant working on this 
disease. We have not asked for an increase for this work, thinking 
possibly that the funds for it might be provided by a special appro- 
priation, so that that is left out, and we can not do anything with the 
item until we find what is going to be done with the special bill for 
cotton work. 
The Cuarrman. Does that include the $15,000? 
Mr. Woops. The $15,000 mentioned at the end of the appropriation 
for this office was first intended, if no other source of help could be 
found, for taking our men off these other problems and concentrating 
them as far as we could upon the problem of securing cottons resistant 
to the boll weevil. It is very important to do this work, and in an 
emergency it could be arranged that we can stop certain other lines of 
work and take up this; but it would mean a stopping of work like the 
beet work, which should be carried on in the interest of the beet 
growers. 
The next matter for which we have asked an increase is the wilt dis- 
ease of upland cotton. The upland cotton disease and the sea island 
disease occur in the southeastern cotton belt, and we have not planned 
to include this investigation in the boll weevil emergency investiga- 
tion in the Southwest. The importance of carrying on this work in 
the upland cotton can be seen by examining the illustrations [exhibit- 
ing photographs] which I send around. There you will see photo- 
graphs of fields completely killed out by this root-rotting disease. And 
you see other plants that are resistant to the wilt. By means of this 
wilt resistant a full cotton crop can be produced on lands where, four 
years ago, the stalk of cotton could not grow. We have settled the 
question for the sea islands, which produce about $11,000,000 worth 
of cotton. We do not need to do any more work there. It has been 
completed, and they have now selections of wilt resistant Sea Island 
cotton that is as good as can be imagined. 
Mr. Scotr. Will not those varieties thrive on the mainland? 
Mr. Woops. No; it is a different kind of cotton. They have the 
same diseases in the upland cotton, but the upland cotton compared 
with the sea island cotton is a different proposition. The loss from 
this disease in upland cotton, in Georgia and Alabama and all through 
that section of the country, is very great. We are now spending on 
upland cotton about $1,000, and we want to increase that by $4,000. 
e want to put two or three men in the field down there, and select 
different plants in the different cotton sections, and perfect the resist- 
ant strains as quickly as possible. We know it can be done, but the 
question now is to get them perfected and into use. If that can be 
done in one year it is a great deal better to do it in one year than to 
spread it over five years. Now, if we could put $4,000 in that work 
for one or two years we could settle the problem in that time. This 
would increase the wilt-resistant work in upland cotton to $5,000. 
Mr. Buruxrson. Is that resistant cotton obtained by a process of 
seed selection? 
Mr. Woops. Yes; we go to the worst diseased fields we can find, 
and plant the most resistant kind of cotton adapted to the locality we
