Mr. Am)KUS«>n. 'IMicrr nro very U'W inf«'staln»n> ? 



Mr. Walton. TIu'It ar«' very f«'w njf»'stiif i"t.^ x ,.- ^ji 



Mr. .VM>KKSt)N. Ar«' tlu'y s<alt«'r(Ml ^ 



Mr. Walton. Tlx'y are scattrrjMl; yes, sir. I hr infestation, as u 

 rule, «l(»t's not run lieavier than I |)er rent in a <nrn(ieltl. that is. 1 

 caterpillar in 1 stalk in HUl. h mtv -.li<_rhl loffvi.ii i.m nn.l it i> 

 almost iinpiissihle to iiiid it. 



To j;o on with the (li>tnl)Utioii of the insect, there ha.> Ix-cii a 

 };;eneral spread to the noitheast\var»l, in the general direetion of the 

 prevailing; wind. Most of this has been in eontij^iioiLs territory. 

 There has been no eommereial spread, or Ion<; jumps, but a spread 

 bv lli^ht of the moth to the north and northeastward. 



In the western end it is negligible, but in the western end of N»-\s 

 York there has been a considerable spread from the west, extending 

 to tlie eastward edge of Wyoming ( ounty. The spread tliere this 

 year eipials the entire area of inf(»station tliat ]ia<l occurred during 

 previous years. 



Mr. Anderson. Is the infestation there light ( 



Mr. W.\lton. Yes; but it is not as light as in Ohio and Michigan. 

 There is some apparent injury, for instance one shipment of sweet 

 corn was taken to a canning factory which had 7 per cent of the ears 

 infested, but that was from a single farm. 



Mr. Ani)f:ksox. ^Vhat would you do in a case of that kin<l '. 



Mr. Walton. Well, they rejected his corn. 



Mr. .Vnuekson. That did not kill what was in it. 



Mr. Walton. There is no way of killing it when it gets in an ear of 

 coriL e.xeept taking it out and smashing it, but the commercial injury 

 is so sliglit it is hard to get farmers to act. The New York people are 

 doing what they can in the way of education, and we are receiving 

 active cooperation from the State peopU\ the New Y'ork and Massa- 

 chusetts people. 



In the eastern area of the infestation in New ^ t)rk that is shown 

 by this red area -the injury is very slight indeed, although the insect 

 has been there for a good many years. These areas, you understand, 

 are areas of one generation of ttie insect, one generation per annum. 



Mr. Anderson. When you sav "these," what do you mean i 



Mr. Walton. P^astern N'ew Vork, western New "\ ork, this corner 

 of l^ennsylvania [indicating on map], the northern part of Ohio, and 

 th(> soutlieastern part of Nlicliigan. 



.Mr. Ander.son. Is that only I year old '. 



Doctor Ball. One generation in a year, and over in Massachusetts 

 it has two. 



Mr. Walton. I was <roing to >a\ thai il had two generations in 

 Massachusetts, so that the insect increases twice as fast in the New 

 Kngland area as it does in these other areas. 



Doctor Howard. There is extraordinary damage in .New Kngland 

 this year, is there not (
