. The Canadian horticulturist [monthly], 1901. Gardening; Canadian periodicals. DETECTING SAN JOSE SCALE ON FRUIT. HEN only a few insects are present on a tree the San Jose scale is not easily detected. If there is fruit on the tree, particularly apple and pear, the pest may be often seen long- distances. On some varieties, especially light colored fruits, the characteristic purplish rings with the scales in the center are very conspicuous. The marking varies somewhat, but is not liable to be overlooked. On pear and apple it is very pronounced and fruit on badly in- fested trees is ofted mottled. The scale attaches itself to any part of the fruit ; but is more abundant on the calyx end. At times there is a depression where the scale is .attached, making the fruit very irregular if badly infested. The accompanying outline shows the scale markings on an apple recently received. It is a peculiar fact that the scale seeks the fruit where there are only a few insects on a tree. When picking fruit, trees from which suspicious specimens are taken should marked. They can be sprayed later and watched. I have known many cases where the scale has been first detected in an orchard on the fruit. The same characteristic purple. Fig. 2198. spot is seen upon the bark of many young trees, and upon the newer growth of older trees. Some apples and pears are often attacked by a fungous disease, producing- a circular reddish or purple marking similar to the scale spot. Care should be taken not to mistake this for scale. The presence of the scale in the center of the circle can be easily detected with a small pocket lens. It is safe to be alert and on guard all the time. —Rural Neiv Yorker. PRUNING THE CHERRY. Could you give us in an early number a short article on pruning the cherry ; there seems to be a great difference of opinion. Some advise heavy cutting out the centre of the tree top when young, others again say never put a knife in the top of a cherry. Richard's Lancing. Chas. Y
