At the time of piekiiig it was I'oiiiul tliat most of the apiihs luul almn-t (•omj)icte)y outgrown the ))laiit-bug injury save for small brown or blackish elevated seal's on the surface. IJadly )>uneture(l a))ples, however, were greatly deformed by llie failure of the iiijmcd areas to grow. The jiercentage of blemished apples could not be determined because the fruit was thinned early in the season and the worst specimens picked off. The San Jose Scale (A-spidiofus pcrniciosx.^) has not yet regained the position it held prior to the winter of K)17-18. Both last year and this year it was dillit-ujt to li)id many badly infested trei's. The insect, however, is gradually iii- cicasing in its old haunts—Jieglected orchards. TiTE Apple Leaf Skwki; (Aricylls niihocnhnui) was present in mo-t orchards ibis aiitniiiii ill iiiodrralc numbers. It is u^uallv a rare insect in Ontari').

Pear Slug (Erwcampoides limacina). The outbreak of pear slug was re- ))eated this year on an even larger scale than tb.at of I'-MS. The foliage of tliousands of pear and cherry trees throughout a large )iart of the Trovince was destroyed, and in the case of early liichmond cherrie- niiirh of the fruit was rendered worthless. Jtist as last year, it was the first Inooi! that did nearly all the damage. In a few localities the serond brood lar\;e were fairly numerous, but in nio-t )daces they could scarcely be said to ha\e done any injury worth mentioning. The eggs of the second brood were this year, as last, highly parasitized. .\ few I'arasites were reared also from the pujiae. EosE CiiAEEPi (MacrodaciyluK siiJ)spiiiosiis).
