Doettir TayU)K. It is not as hard as spring; wlieat, hut lias a total 

 food vahie per acre in exei'ss of the hard sprin;;. It is not to he 

 expected at all that we ever will hav<> wint4'r wheats that will 

 entirely displace spiin;; wlu-at in our more northern tt'rrilory. We 

 do not know of any types t>f wheat that appear to possess hardinea>< 

 sullieient to stand the winters of the northern Clreat Plains nrea 

 .ifter vou tret up into the Dakotas. up to North Dakota, particularly, 

 hut then' is reason to helieve that there are cold <'ndurin;^ tyf)es «jf

 have vet. The proi^ress that has hcen made in the hrecdin;; work

 increase of winter hardiness can he accomplished in tiic ease of wheat 

 that would make it possible to push winter wheat production eon- 

 siderahlv farther north thnii it ev<T has been in this countrv. That 

 would be an important and very <lesirable ihinj; to uccomplish. On

Mr. Andeu.son (interposing;). Did you finish this^ 



Doftor Tavi.oij. I bei; your j^ardon. Do you wish ^omc informa- 

 tion upon the barberi'v eradicalitm '. 



Mr. Andkk.son. I wanted some information on barberry eradica- 

 tion. Hut I understand that this S2o.l)()() is going to be used entirely 

 on this wheat business. 



Doctor Taylor. On wheat and corn. 



Mr. .Vm)KI{S()n. Wheat and corn. I want a good deal of informa- 

 ti(»n on this barberry eradication plan. 



Doctor Taylor. I would suggest that Doctor Kellerman has a 

 map here that will help you to understand it. 



BARBERRY ERADICATION. 



Doctor Kellerman. Mr. Chairman, the work of barberry eradi- 

 cation was considerably enlarged during the past fiscal year, because 

 of the increased funds put at the disposal of the bureau bv the last 

 Congress. A very small map that 1 have here will be the easiest 

 wav for you to visualize, approximately, the progre.ss of the work. 



The plans of the activity have been to center the inspection ami 

 eradication work in those areas where losses have been severe, where 

 the escape of the barberry, if it oeeurred (piite generally and there 

 were delays in eradication, would, therefore, result in a very much 

 harder campaign as each year went by. Accordingly, the most 

 critical insj)ections and the hea\ iest exi)en<litures have occurred in 

 the central portions of the area of the 13 States- 



Mr. Ander.son (interposing). Will you name the States^ 



Doctor Kellei{Man. They are North Daki)ta. Minnesota. South 

 Dakota, and Iowa. The inspections there have been conducted in 

 about one-half, a little bit more than on(»-half. of the areas that we 

 think must be very carefully inspiM'ted and inspected on a farm- 

 to-farm basis before we can assume that the eradication work ha.s- 

 been accomplished.
