wheat, reckons that " mildew caused from one to two quarters 

 less yield, which at present value would De 28s. and 5 6s. per 

 acre." Besides the loss of weight of grain, the straw where mil- 

 dewed was of indifferent quality. Thus Mr. Clare Sewell Read 

 reports : " On the twenty-five acres, all the thin-planted part 

 of the field was badly blighted, and the straw very much dis- 

 coloured and spoiled, but little apparent damage was done to 

 the grain, which was a fair crop and a nice sample. Mr. 

 Charles Howard, of Biddenham, Bedford, says, " the straw was 

 more injured than the corn." Mr. Gearey, dating from King's 

 Langley, Herts, remarks that the estimate of injury caused by 

 mildew on his farm is " about 305. per acre, including damage 

 done to straw, the greater part of which is rendered black and is 

 very rotten." Mr. Allsop, of Romsey, Hants, who sowed forty-two 

 acres of wheat, puts the reduction of the yield at one-half, and 

 states " that the straw is very black." 



On the other hand, it was found by some reporters that 

 though the mildew was present no actual loss was experienced. 

 Mr. Glenny, of Barking, Essex, noticed that a portion of hi? 

 wheat plants were mildewed, but records no damage. Mr. 

 Philip Shepheard, of the Hall Farm, Hunningham, near 

 Leamington, makes the following observations : " I do not 

 consider in my own case that very much damage has been done ; 

 the yield will not be affected probably beyond about two 

 bushels to the acre. The warm sunny days we had in the 

 middle of August came just in time to arrest what threatened to 

 be a serious attack." Mr. Palmer, of Revell's Hall, Hertford, 

 considers that the value of the straw upon a large portion of his 

 wheat land was reduced by 105. per load. 



Date of Appearance of the Rusty (Uredo) Form. 

 Concerning the dates of the appearance of the yellow, or 

 rusty (Uredo), form of the mildew, there is a great difference in 

 point of time. In some cases it was noticed at the end of May. 

 In others not until the end of July, and even as late as the 

 first week of August. Mr. Clare Sewell Read remarks that 

 after the heavy rains of the middle of July, accompanied by a 

 sudden fall of temperature, some rough spots were observed 

 under the ear, and then the yellow rust became general 

 towards the end of the month. In Suffolk, Mr. Smith, of 

 Rendlesham, perceived it just before the wheat came into ear. 

 Mr. Gibb, of Lymington, Hants, first saw rust " about the 2oth 

 of June, when plants had been about a fortnight in ear, but the 

 attack was not very severe until the 2oth of July." Mr. Galpin, 

 of Blandford, Dorset, did not notice any rust until after the 

 severe frost of June 13 and 14. At Cardington, near Bedford, 

 Messrs. Maiden found rust " on June loth ; the ear was just 

 bursting the sheath." 



Date of Appearance of the Black (Teleutospore) Form. 

 The black form (Teleutospore) showed itself also at some- 

 what varying periods. The earliest note of it was made on the
