The spraying must 'be very thoroughly done, so that every part of the tree from 

 the ground up is covered. It should not be done when the bark is wet or the tem- 

 perature is below freezing point. 



This spraying would pay even if thefe were no scale, and our best apple growers 

 regularly apply it along with two or more later applications to keep their orchards 

 healthy and the fruit clean. 



Lime-sulphur is the best and cheape&t well-tested remedy. 



It is usually possible to control the scale in one's own orchard independently 

 of neighbors. 



All nurseries to-day are inspected, and infested trees broken down and burned. 

 No nurseryman is permitted to sell nursery stock without its being first fumigated 

 with hydrocyanic acid gas.

SAN JOS£ SCALE.

Introductoky. — With the renewed interest of the last few years in fruit grow- 

 ing, and especially in apple growing and in the renovation of old apple orchards, 

 has eome a new interest in the different insect pests and diseases of the orchard. 

 Of these foes the most destructive, wherever it occurs and is able to thrive, is the 

 San Jose (pronounced San Ho zay, or San H5 say) Scale. This insect infests only 

 a small part of the Province, but a part that is admirably adapted for fruit grow- ' 

 ing, hence the importance to the orchardists in these districts of being well in- 

 formed on the means of jdentification, habits and best methods of controlling this 

 pest. Interest, however, in the San Jose Scale is by no means limited to the in- 

 fested areas, because progressive fruit growers in other parts of the Province, hav- 

 ing heard or read reports of its destructiveness elsewhere, are anxious lest it get
