XI. 



State any other particulars bearing upon the question. 



Extent of Injury. 



Taking these questions seriatim, it appears from the answers 

 received to No. I. that thirteen correspondents, in the counties of 

 Bedford, Berks, Cambridge, Essex, Gloucester, Hants, Hereford, 

 Lincoln, Norfolk, Northumberland, Somerset, and Warwick, 

 reported that all, or nearly all, of their wheat was affected. 



A similar number of observers, in the counties of Bedfordshire, 

 Dorset, Essex, Hertford, Kent, Norfolk, Suffolk, Warwick, Wilts, 

 and York, reported attacks of rust in varying percentages of their 

 crops. 



On nine farms in the counties of Essex, Monmouth, Northamp- 

 ton, Northumberland, Stafford, Surrey, and York, no attack of 

 rust was observed. 



Estimates of Loss from Mildew. 



With regard to the amount of injury caused by the mildew, 

 this is estimated, in the answers to Question No. II., at from 

 nine bushels on a farm in Kent, to as high as sixteen bushels per 

 acre upon land at Dillington, Somerset, as returned by Mr. 

 Obed. Hosegood. Upon one farm in Norfolk, at West Barsham, 

 the loss is set at from four to sixteen bushels per acre. Mr. 

 Albert Pell puts the diminution in the yield of 120 acres in 

 the Isle of Ely, on account of the mildew, at from 100 to 150 

 quarters. Mr. Palmer, of Re veil's Hall, Hertford, estimates 

 his loss at 1507. on seventy-five acres of wheat land. Mr. 

 Martin, of Littleport, Ely, considers that his crop was decreased 

 from two to four quarters per acre, adding that " it is the most 

 serious and universal attack I have known for many years." Mr. 

 Game says of a farm at Great Rissington, Bourton-on-the- 

 Water, Gloucestershire, that the loss on twenty acres of wheat 

 and from mildew equalled 35 per cent. Mr. Murton Matson, 

 of St. Osyth, Colchester, states that it is hard to tell the 

 amount of loss, but certainly three sacks per acre: Mr. 

 Charles Clarke, of Scopwick, Lincoln, who sowed 125 acres with
