\^ (-' can, lio\ve\'L'r, lessen their nnnilier onvwelves \'ery easily. To 

 acconiplisU this all we h:i\-e to ihi is to tic a liaml of hay or old chjth 

 around tlie tninlv of the tree cLise to the j^'round about June. If we 

 examine (he hand in the winter AVe sliall often hiid it full of tlie 

 cocoons ijf ilic (_'i)dling ]\Ioth. These bands can lie iiurnt, and so very 

 great niimliers of the pest may be destroyed. Several correspondents 

 have written stating that tliey have collected larne nnndjers of the 

 uum;i.;-ots during the past few years by banding- the trees, and that, 

 in conseijueiiee, the nnndier of maggoty ap]iles have liecn much 

 reduceil. Uld manure sacking is very suit- 

 able for this purpose. 



A lew remain, having come down from 

 aliove, and will hatch out and lay their 

 eggs, these may be coped A\'ith by sjiraying 

 the trees with an arsenical ]joisou dii'ectly 

 the blossom has fallen. The poison lodges 

 in the eye of the apple, and the first meal 

 the young cater[)illar tak'es is arsenic, instead 

 of apple, and so it is killeil. 



This spraying slioirld take place not later 

 than ten days after tlie blossom has been 

 shed. At tlie same timi_' the fungicide 

 Ijordeaux mixture may be used with the 

 arsenate of lead. The latter can now fie 

 obtained in paste form (Swift's Arsenate of 

 Lead Paste), which is more convenient to use than the home-made 

 mixture. 



This spraying must be done properly tn be successful. As 

 line a mist as possible must lie tlirown out, so that it penetrates 

 well into the calyx. A great deal depends upon the right time of 

 application. In a mixed orchard, it is cif course impossible to do 

 this at one operation, owing to the varioiis times of blooming. For 

 other reasons as \vell, it is thus ad\'isable to grow eml)' one or two 

 kinds of apples in each pilantation. 



Of the three arsenates used for this purpose, viz., Talis green, 

 London purple and arsenate of lead, there is no doubt that the 

 last-named is much tlie most potent. The following table (3) 

 may here be liuoted showing the benefit derived from arsenical 

 spraying.
