 and slightly damaged but generally picks up quicker than other varieties 

 after an attack (A.B.) Stands attack fairly well but have seen suffer 

 severely (J.G.) Generally better than the others (W.H.B.) A few fields 

 badly damaged at Brechin Castle in 1917 but resists blight fairly well 

 (J.W.A.) Generally better than any other cane I know (G.'J.R.) 

 Generally better than others (G.H. Hill). One of the most resistant, in 

 1917 the froghopper attack spread across the estate but jumped all the 

 fields of D. 1U9 (H.T.C.) Standing out among B. 347, Reform 1918 

 (C.B.W.) Standing out among B. 156, Reform 1918 (C.B.W.) Not

I/ca/ Z) /.seas?.— This variety is particularly liable to a leaf disease 

 which, at the end of the wet season causes the leaves to be marked with 

 elongated brown streaks which may coalesce and cover the whole leaf. 



Mr. Nowell after a preliminary examination believes the disease to 

 be Helminotlios]}orium, known as " eye spot " disease. 



Up to the present it has never occurred sufficiently early in the year 

 to cause any serious harm. 



In a field of mixed D. 109 and B, 156 at Golconda in 1917 every 

 plant of D. 109 was heavily infected while the leaves of the B. 156 were 

 still healthy and green.
