Fig. 6B.— Map indicating, in bold faced type, the approximate dates 

 immediately after which it is usually safe to sow wheat in the 

 fall, in various sections of Ohio, in order to avoid the autumn 

 attack of Hessian fly. Dates given in small type show when 

 Avheat sown in the fall of 1899 escaped the fall attack, though 

 it was in many cases totally destroyed by the spring attack. The 

 difference between these dates is the variation from the normal, 

 and where no dates are given between the cross-lines there waa 

 no such variation. (After Webster.)
