Frequently Aphides, especially Myzus cerasi, infest the young Shoots and foliage ; but the XL All Insecticide or McDougall's fumer will quickly destroy these pests. The syringe should be used freely while the trees are growing, except when they are in blossom and when the fruit is ripening; this will assist to keep the foliage healthy and clean, and at the same time will encourage a sturdy habit. When our trees have produced a great mass of flowers we have with good effect cut away all the worst-placed with a pair of grape-scissors; the remaining flowers received extra support, and always set more freely than on trees not thinned. The following sorts are admirably suited for growing under glass: Early Rivers, Belle d'Orleans, Bigarreau Jaboulay, Governor Wood, Guigne de Louvain, Late Duke, May Duke, Nouvelle Royale, Royal Duke, Ronald's Black Heart, and Emperor Francis.

When the fruit is picked, the trees should be induced to rest as mentioned under Apricots, never allowing them, however, to suffer for want of water at the roots. Outside the other animal pests which it is proposed to deal with under general headings, there are only two calling for special mention.

Prior to that it has undergone several changes, and in the first stages of that condition it has a most disgusting look, owing to its exudation of a black slimy secretion. The head is abnormally big, and make's the insect look repulsive. When nearly full - fed the slime disappears. The pupa - state is passed in an earthen cocoon in the soil, a little below the surface. The perfect insect has a black body and transparent
