leaf. In fact, I think if you will examine a fruit tree in London after a 

 London fog you will not find nearly as much deposit on the under side 

 of a leaf as you will on the top side. 



Mr. Neame : As there has been some little doubt about the efficacy of 

 spraying with Bordeaux mixture for scab, I should just like to make a 

 few remarks about my own experience. I first used it five or six years ago 

 on a few trees. While hitherto for two consecutive years I had picked 

 hardly any sound fruit, the first year I made the acquaintance of 

 Bordeaux mixture I tackled it by spraying the trees in the winter, once 

 before blossom and twice afterwards. That year I had a fairly sound crop. 

 For the last three years I have had a good sound crop of fruit with hardly 

 any scab on them. The spraying, as far as my experience goes, is 

 certainly better done in the summer. If I had a very bad attack I should 

 be inclined to try it in the winter too ; but the first spraying should be 

 done just before blooming and the next one as soon as the blossom has 

 fallen. Those two sprayings should be sufficient, unless in an old and 

 badly attacked orchard. I have had further experience this year ; I 

 wished to put off my spraying till the last moment, so as to make it last 

 longer into the summer ; and I did not put on the Bordeaux mixture until 

 I saw a few signs of scab on the leaves, and, of course, then it was 

 undoubtedly too late. Instead of getting a good crop of sound apples I 

 only got a small crop of very scabby ones. It appears to me that the 

 second spraying with Bordeaux mixture should be as soon as ever the 

 blossom is falling. The Bordeaux mixture I always prepare myself. 

 The lime is mixed up with a bucketful of water, and the mixture is poured 

 into a big tank where the copper sulphaie has already been dissolved, 

 and that seems to give very good results. In most apples I do not get 

 any scorching, and I get fairly good results with regard to the curing of 

 the scab. To produce thoroughly good apples I should undoubtedly say 

 that Bordeaux mixture must be used ; and in regard to pears that good 

 pears can hardly be grown without the use of it. There are certain 

 apples, of course, to which this remark does not apply, which do not 

 appear to be attacked by scab ; those, of course, growers are probably 

 acquainted with. 



Rev. George Engleheart : As time is short I should like to bring 

 a small concrete instance before the meeting, because what I think we 

 want is absolutely concrete instances, and we want advice ; we want 

 either help or discouragement according as it can be given. I had a very 

 great deal of satisfaction in listening to Mr. Massee's able but eminently 

 discouraging address, because it coincided so entirely with my experience 

 in the way of discouragement. My case is one of Cox's orange and the 

 leaf-spot. I live a few miles west of Salisbury ; and in the whole of that 

 district we are suffering the very greatest damage, a progressive and 

 increasing damage, every year from the apple-leaf spot — that spot which 

 was so excellently described by Mr. Chittenden in the last issue but one 

 of the Society's Journal. I have had a great deal of illuminating 

 correspondence with Air. Chittenden, who has been very kind indeed to 

 me in the way of writing. His paper was such an excellent paper as 

 regards the diagnosis of the disease that in itself I think it quite justifies 

 the existence of the Wisley Laboratory. My experience in the matter is
