GENERAL PEENCIPLES. 



surer, being more likely to escape frost. These diiferences 

 are caused by various circumstances. 



1st. The Climate. — ^The period of blossoming of the same 

 species varies much in different localities. Rochester is 

 at least a week earlier than Buffalo, although the distance 

 is less than one hundred miles ; and it is nearly two 

 weeks earlier than Toronto, which is still nearer. The 

 large bodies of ice in the lakes, at both Buffalo and Toron- 

 to, have no doubt a considerable effect in retanling the 

 blossoming period. 



2d. TJie Seaso7i and Position. — In the same locality, 

 one season is frequently a week earlier than othei-s, and 

 trees on the south side of a wall or building will expand 

 their blossoms several days before the same variety in the 

 open ground only a few rods distant, and ten days to a 

 fortnight before those on a north wall. 



3d. The Soil. — On warm and light soils, the roots of 

 trees are excited into activity much sooner than in cold, 

 damp, and heavy soils, and the blossoming period is ear- 

 lier in consequence. 



The different Character of Flowers. — ^Flowers vary in 

 size.^ form.^ color .^ and other qualities, even in the same spe- 

 cies. In the peach those distinctions are so obvious, that 

 one of the principal classifications of pomologists is found- 

 ed on them. Thus there are varieties with large.^ shoioy 



floioers (fig. 39), as the sei^rate 

 early Yorla^ and small (fig. 40) 

 as large early Yorh^ Craw- 

 ford Early ^ etc. The color 

 also presents variations, some 

 being deejy^ others pale rose, 

 and some almost white / two 

 or three varieties of the 

 peach have flowers wholly 

 white, as the snoic.^ for instance. In all the other fruits,
