It can be controlled by thor- ough work with a spray of whale - oil soap, one pound in three to five gallons of water, begin- ning soon after the fruit has set, and repeating the application whenever the psyllas become nu- merous. In some parts of the East the fruit is attacked by the Pear midge, a minute fly whose maggots work in the very young fruit. Thorough cultivation will check this seri- ous pest, but its complete control often involves the destruction of all the young fruit on the infested trees; in some sections the application of kainit to the soil is said to kill the insect after it leaves the fruit to un- dergo its transformations. The foliage and fruit of the Pear are attacked by para- sitic fungi, w^hii'h cause the leaves to drop and the fruit to become scabby. These diseases are readily held in check by spraying with Bordeaux mixture. Fifty years ago the White Doyenne Pear was the most popular va- riety for growing on the quince root, but because of the Pear scab it passed away. It was supposed that the disease was due to uncongenial climate. Since the ad- vent of the sulfate of copper sprays, however, it has been found that the White Doyenne
