ii2 Injury to Foliage by Bordeaux Mixture, [may, 



Stirling Castle, were sprayed twice. By July 27th a 

 large number of trees in the plantation showed a 

 "scorched" appearance round the edges of the leaf, or 

 extending over the greater part of the leaf ; in severe 

 cases whole boughs looked as though their leaves had been 

 scorched by fire. In a few instances a single bough, or one 

 or two boughs, showing this scorched appearance appeared 

 on a tree, while the leaves on the remaining boughs were green 

 and uninjured. Investigation showed that this injury was 

 quite as pronounced on the unsprayed trees as on the sprayed 

 trees. Some of the facts observed with respect to certain 

 varieties are of interest. In one strip of the plantation a row 

 of 94 trees of Wellington were sprayed ; some of the trees 

 subsequently showed the "scorched " appearance of the leaves 

 described above ; the same kind of injury, however, was 

 much more marked on the two rows of trees, on either side, of 

 Worcester Pearmain and Lane's Prince Albert, although 

 these had received no spray. The injury was so severe on 

 the Worcester Pearmains that the trees were weakened to 

 such an extent that the apples never developed to their full 

 size, but dropped off. In a row of 88 trees of Newton 

 Wonder which were sprayed, no injury appeared except on 

 the trees which crossed a plot of ground where a manurial 

 experiment — -under which the trees had been partially starved 

 — had been carried on ; here the leaves turned brown at the 

 edges or ultimately died. This fact suggests that injuries 

 due to climatic conditions are most liable to appear on trees 

 that are not vigorous. Another variety which presented the 

 " scorched" appearance to a marked degree and which had 

 not been sprayed was Hoary Morning. The varieties which 

 were sprayed and which showed no injury of any kind on 

 the leaves were as follows : Ecklinville, Warner's King, 

 Blenheim, Stirling Castle, Cornish Gilliflower. 



Another very interesting case occurred in a plantation at 

 Teynham, Kent. Here at the beginning of August last 

 year a large number of trees of the varieties Beauty of 

 Bath, Cox's Orange Pippin, King of the Pippins, Charles 

 Ross, Allington Pippin, and Peasgood's Nonsuch showed 

 exactly the same kind of injury as noted above in the case 

 of the trees in the plantation at Wye College, the leaves 

 being brown and dead at the edges or tip ; while in one variety,
