204 AGRICULTURAL APPROPRL\TION BILL, lifH. 



Mr. AxDERSox. What proportion of these 18 States have been 

 surveyctl for the first time ^ 



Doctor Stakmax. The cities and towns have been surveyed in all 

 the 13 States, and as far as the country districts are concerned I 

 should say possibly about half or more; that is. as far as the farm to 

 farm survev is concerned. May I make just one more statement ? I 

 just want to point out the destructive effects of a single barberr\ 

 oush. This is a statement made by Doctor Jackson, of Indiana, who 

 has been one of the most conservative of the plant patholoijists in 

 connection with this barbeny eradication campaign. He says: 



One thing that hag greatlv interested us this summer and on which Mr. Heeson. onr 

 State leader, made a special study, was an outbreak of stem ru.st that started from on- 

 barberry bush. It traveled iu one direction, at least, for about 5 miles. The an a 

 was tiretty carefully surveyed and I have a report here containing figures given li 

 the farmers themselves on 18 out of perhaps a total of twice that many farms. Thf 

 total wheat acreage was 963 acres. The average yield due to stem rust was S. 1 busheln 

 The average estimate of yield had there been no black-stem rust was 21.4 bushels. 

 The average crop this year was then 37 per cent of what it would have been without 

 the black-stem rust. The total lost in yield was 12.520 Inisheis or an average la'ss ofV 

 696 bushels. At a dollar a bushel each farmer lost .?696 worth of wheat. The com- ,- 

 bined money loss was $12,520. '; 



That was very clearly traceable to a single barberry bush in the| 

 southern one-third of Indiana. I have a great many similar cases/ 

 but I was interested in that because Doctor Jackson has been so 

 conservative on the thing. 



Mr. Fuller. I can answer in part the question which you just 

 asked, Mr. Anderson. Dr. F. E. Kempton. the leader of the campaign 

 of barberry eradication for the United States Department of Airi- 

 culture, made this statement at our recent meeting in St. Paul: 



A total of 172 counties were covered, as against 86 in each of the two preceding^ 

 years. 



During the entire campaign since 1918 an area of 512 counties has been covered 

 in the farm-to-farm survey. The total number of bushes found was 5.806.64;V Of 

 the.se 5,142,843 were destroyed. 



With reference to the future he m'ade this statement: 



« 



A large area remains to be covered by our original farm-to-farm survey. \l the 

 rate we went this year, it is possible that next season we can complete the survey 

 in Minnesota. Nortli and South Dakota, Iowa, and Nebraska. 



Without knowing how many counties there are to be covered 

 wc could not give you the geographical proportion which has ah-cady 

 been covered. 



Mr. Anderson. Judging from the map I have beft>re me all ofi 

 the territory of Minnesota has been surveyed, that sm'vey having 

 apparently been completed this year. 



Mr. Fuller. Not all of it, 1 think, Mr. Anderson. There are a 

 few counties in this area here [indicating on maji]. 



Mr. Anderson. But most of those on this map are marked as 

 probably not needing surveys. 



Mr. Fulleh. This is Doctor Kempton's maj). We still have a few 

 moments of time and I woidd like to make an adilitional statement.' 

 1 want to tell yon something about the work of the organi/.ation 

 which we represent. 1 told you what we had done in the way of 

 sendiirg out publicity material, and it will interest you to know that 

 we have expended in that work up to date about S.">().0()(): we will 

 have spent by (he 1st of March about StW). ()()(). and we are plamiing
