or six weeks farther in the seasou hy a mean tempe- 

 rature of 55 degs. The peach may be subjected at 

 first to a temperature of 45 degs., but not exceeding 

 55 degs. till the flowering is over, after which it may 

 be gradually raised to 60 degs., and not exceeding 65 

 degs., till the substance of the stone is indurated ; 

 and after this crisis from 65 to 70 degs. may be al- 

 lowed. This is to be understood as referring to the 

 application of fire-heat. Even in the total absence o 

 the latter, sun-heat will frequently raise the tempera- 

 ture much higher ; but in this case a large portion of 

 air should be supplied, not, however, all at once after 

 the temperature of the house is found too high, but 

 gradually as the temperature increases. Air should 

 be always freely admitted through the day when the 

 weather is at all favourable. {LoudorCs Suburban

As it is injurious to subject the peach to a high 

 day temperature during its blossoming period, so is it 

 still more injurious to allow it to endure a high night 

 temperature, at any time of its growth. We have 

 had it as low as 34 degs. without any injury, both 

 when the trees have been in blossom and when the 

 fruit has been as large as small marbles ; and we are 

 quite sure that from 40 to 45 degs. is the best night 

 temperature during all its periods of growth. Some 

 gardeners, however, use considerably higher tempera- 

 ture ; but although they obtain a ripe crop somewhat
