380 CLIMATIC VARIATIONS. 



game degree of latitude. As soon as we pass beyond the influence 

 of the water, a marked change of climate is noticeable. In the 

 northern interior parts of Ontario only the hardy Morello Cherries 

 can be grown, the Hearts and Bigarreaus disappearing altogether ; 

 many of the choice varieties of the Pear fail, and some of the 

 Apples prove too tender. Yet again, in some of the small fruits 

 and the smaller growing ornamental shrubs, the protection 

 afiForded by continuous deep winter snows more than counter- 

 balances the change of atmospheric temperature. Hence it is 

 that in northern Ontario and* in the Province of Quebec, all 

 V-arieties of Easpberry and Blackbery are hardy, and many other 

 plants and shrubs that perish or suffer severely where the winters 

 are open, are there so completely shielded by the snow, that they 

 pass the winter safely, and are cultivated without difficulty. 



In the Province of Quebec, only the hardier varieties of Apple 

 can be grown, a limited number of Pears, and only the Morello 

 Cherries, while the Peach wholly fads, and the Plum must be 

 substituted in its stead. In the vicinity of Montreal, such Apples 

 as the Early Joe, Fameuse, St. Lawrence, Pomme Grise, Alexan- 

 der, Duchess of Oldenburg, Eed Astracan, Borassa, and Eibston 

 Pippin thrive weU ; and with them such Pears as St. Ghislain, 

 Flemish Beauty, Oswego Beurre, White Doyenne, Osband's 

 Summer, Napoleon, Tyson, Belle Lucrative, Doyenne d' Ete, 

 Lawrence, Beurre d'Amalis, Beurre Hardy, Duchesse d'Orleans, 

 Beurre d'Anjou, Louise Bonne de Jersey, Dana's Hovey, and 

 "Winter Nelis. 



In that climate, the Pear tree may be easily made so tender 

 by manuring, as to be seriously injured, and oftentimes kdled 

 outright by the cold of winter, while, if they are allowed to grow 

 more slowly, without the application of stimulating manures, 

 they produce a better ripened wood, more capable of enduring 

 the severity of winter. 



So common is the error of stimulating the trees into a too 

 luxuriant growth, that an intelligent observer writes to us that 

 ninety per cent, of aU the Pear trees which are planted and grow
