VI PROCEEDINGS. 



parent that a large quantity of food is in a small space. I may 

 add, that from some recent experiments with compressed earth to 

 potted fruit-trees, I have a high opinion of its effect, and I fully 

 believe that we have yet much to learn on the subject." 



A Queen Pine Apple, weighing 5 lbs. 4 oz., was furnished by 

 Mr. Fraser, Gardener to the Earl of Radnor. 



Mr. Brown, Gardener to PI. Minton, Esq., had a Ripley 

 Queen Pine Apple weighing 4 lbs. 14 oz. 



A dish of Black Hamburgh Grapes was exhibited by Mr. Rust, 

 Gardener to J. Maclaren, Esq., F.H.S. 



Examples of the same kind of Grape were sent by Mr. Fry, 

 Gardener to Mrs. Dent, Manor House, Lee, Kent, to show the 

 effect of sulphur in killing Vine mildew, which has been so pre- 

 valent of late years both in this country and on the Continent. 

 Mr. Fry's mode of dealing with it is as follows. He says : 

 "With reference to the Grapes exhibited by me, I may state that 

 they were grown in what I term my third vinery, in which arti- 

 ficial heat is but rarely applied. The fruit in this house last 

 year was fearfully attacked with mildew, which suggested in 

 the first instance the diffusing of sulphur by more efficient 

 means than had hitherto been employed, namely by the sul- 

 phurator. This season the Grapes in the same house were 

 attacked as seriously as in the preceding year, but on perceiving 

 the mildew make its appearance I instantly took prompt mea- 

 sures to subdue it. Being provided with my improved sul- 

 phurator, I diffused ' sulphur vivum ' in a perfectly dry state 

 throughout the house so as to finely but thoroughly cover both 

 fruit and foliage. Fires were lighted and the temperature kept 

 up to from 80° to 90°, ventilation being considerably dimi- 

 nished, and water in any form discontinued. After being sub- 

 jected to this treatment for about four or five days the vines 

 received a thorough syringing, which cleansed them from every 

 particle of sulphur. With respect to the use of sulphur in 

 killing mildew, many ladies and gentlemen with whom I have 

 conversed consider it highly objectionable : they say that they 

 do not like the idea of eating sulphur with Grapes, neither would 

 any one, and I can prove to them that this need never be done, 

 and, moreover, that the use of sulphur when timely and judi- 

 ciously applied does not in any way deteriorate the fruit. I 

 much question if the most practised eye could detect sulphur 

 on the Grapes exhibited, although they have been twice covered 

 with it ; and as to the mildew itself amongst vines, I fear it no 

 more than I do greenfly amongst cucumbers, which is so soon 

 deprived of existence by the fumes of tobacco." 



A round white Potato, called Prince Albert, was produced by
