during cold, Avindy, or frosty Aveatlier, the Cherry-liouse should 

 never be altogether closed, or without the means of obtaining a 

 circulation, which can and should be procured without creating a 

 draught. An opening or two along the ground line, where the 

 fresh air will pass through or over the hot-water pipes, can 

 easily be arranged without detriment to anything. The application 

 of moisture, both over the branches with the syringe or engine, and 

 also at the roots, is a necessity of all culture under glass, and the 

 chill should be taken off all water used in forcing-houses. Water 

 used for syringing must be soft and free from impurities. 



Insects. — As soon as the blossoms and green leaves appear, 

 the green Hy will probably appear also, and must be dealt with by 

 iumigation. The black aphis comes later on, and is more difficidt 

 to destroy ; but dusting with Tobacco powder, and one or two 

 fumigations, usually clear them off. If the red spider api)ears in 

 large numbers, it may be taken for granted that some mistake has 

 been made in the interior of the house, generally by keei^ing the 

 borders and the atmosphere too dry, with, perhaps, deficient 

 ^•entilation. Strong robust foliage, such as is growing on trees 

 well cared for, is not often attacked ; or if it is, the syringe soon 

 makes short work of the spiders. 



Cherries in Pots may be grown where no special house is 

 set apart for them, and they force readily enough when not hurried. 

 They will do in the Orchard-house, or in any house where there is 

 plenty of light, with a low temperature and proper atmospheric 

 condition. A firm root-run is essential to all stone fruits, and 

 very often when difticulties appear about the stoning time, they 

 may arise from a deficiency of lime in the soil, unless some other 

 more likely cause be present. Stone cracking and the casting of 

 the crop prematurely are generally produced by a deficiency of 

 lime. 



Varieties. — May Duke is the best for forcing. Early Purple 

 Gean, Belle de Orleans, Governor Wood, Werder's Early Black, 

 Archduke, Royal Duke, and Late Duke. 



CHAPTER IX 



The Pine Apple. — Though Pine growing in this country is 

 for the present languishing in face of foreign competition, yet, as 

 history repeats itself, something may occur to bring the king of 

 fruits into such repute as to make its re-cultivation at home 

 remunerative. I sliall not enter minutely into this matter, but 

 only state what I consider to be the chief essentials.
