Flowers.—In a a wtih in the Chro- 
nicle of of 20th Aug. last, in endeavouring to explain the 
cause of the change of colour i ‘in ‘the Phlox, you observe 
either to the absorption or exhalation of ee all- -important 
element, oxygen; and that the change in the colour of

+ Pruning of Pear-Trees—In Nos. 34 and 35 
of the Chranicte, Mr, Ayres has made some comments on

he garden and neatly-tri ar out in

atone for the want of fruit. e pleasures of gardening 
may be ho Si to mixed onions ; and harmony in ye en 
scenery is, I conceive, produced by a combination of parts, 
foing a whole ; sk if the fruit- coon is not what 
ht to be, a link is displaced in the chain... The ob- 
jee ect of the teat must be fulfilled, and the production of 
fruit rab -onsideration ; so
