PEOGEESS IX BAEBEEEY EEADICATIOX IN 

 ILLINOIS DLTJIXCt 1919. 



By L. E. Tehox, United States Department of 

 Agriculture, Ubbana. 



The barberry eradication campaign had its beginning, 

 in the state of Illinois, in the spring of 1918 under the 

 leadership of Dt. F. L. Stevens and Dr. H. "W. Anderson. 

 The results of the year of 1918, briefly restated from Dr. 

 Anderson's report, indicated 36.419 bushes found. Dr. 

 Anderson's report states confidently that '^seventy per 

 cent of all of the barberries in Illinois have been removed, 

 or vrill be removed before next spring". Dr. Anderson 

 likewise speaks of bushes escaped from cultivation as 

 follows: "It is evident, however, that the shrub is not 

 very widely distributed in the woods and pastures to 

 date". As it now appears, these last two statements by 

 Dr. Anderson were far too optimistic. 



The campaign of 1919 opened in March under the lead- 

 ership of Dr. F. E. Kempton, Dr. F. L. Stevens resigning 

 his place in favor of Mr. P. A. Glenn, Chief Inspector 

 for the State Division of Plant Industry. Dr. Kempton 

 left Illinois to become federal leader of the campaign on 

 June 30, 1919; and was succeeded by L. E. Tehon.
