rams and dews. The canvass is found to be of great 

 utility in bright sunny weather, when the trees are in 

 full blossom; for the peach and other stone-fruit, 

 which in their native country blossom at an early 

 period of the season, whilst the air is yet cool, do not 

 succeed so well in setting when the blossoms are ex- 

 posed to as much as 100 deg., which they frequently 

 are, against a south wall. The thin canvass admits 

 also plenty of air ; w^hile woollen netting, which it 

 might be thought would admit still more air, was 

 found to render the leaves too tender, in which case 

 they suffer from the intensity of the light when the 

 netting is removed. Common thread netting is not 

 liable to produce this effect, being much more airy ; 

 and this netting has the advantage, when not placed 

 farther than a foot from the wall, of admitting of the 

 trees being syringed through it. Very little syring- 

 ing, however, is required till the trees are out of blos- 

 som, and none while they are in blossom ; and when 

 the space between the canvass and the wall is nine 

 inches wide at top, and four feet wide at the bottom, 

 as in the Horticultural Society's garden, the syring- 

 ing can be very well performed in the space within. 

 Perhaps it would be an improvement in the case of 

 the Horticultural Society's wall, to have the coping as 

 much as eighteen inches wide, as no frost, unless very 

 severe indeed, would injure the blossoms of fruit trees 

 trained against a wall with such a projection ; but the
