ON VINERIES. 



or three weeks j after which, the house, or pit, may be 

 closed, excepting in sunny and mild weather. By adopt- 

 ing this suggestion, the roots may be got a little in 

 advance of the top or canes ; they then break more freely, 

 and succeed better. I advise to begin with a temperature 

 of 50° at night, and 55° to 60° on dull days, with a 

 little air on if not stormy. If it be sunny weather, the 

 thermometer may be allowed to rise from 5° to 10° higher, 

 taking great care to give air very carefully, and by 

 degrees, as the temperature rises. In about a fortnight 

 the temperature may be raised to G5° on dull days, with 

 a little air on if not stormy; and 5° to 10° higher on 

 sunny days, giving air as advised above. The bottom 

 heat may be increased a few degrees, taking care to 

 have a free circulation of air. If the weather is stormy 

 and cold, no doubt there will be sufficient air through 

 the laps of the glass and other crevices. The cultivator 

 -must be entirely guided by the weather, so far as giving 

 air is concerned ; in fact, he ought to study nature, which 

 should be his principal guide. 



If the sun should come out suddenly, and prove too 

 hot, every effort must be used to give a little air, although 

 it does happen to be stormy, as there is often a great 

 deal of damage done to the crop in such weather at this 

 stage of the vine's growth. If it can possibly be avoided, 

 however, the thermometer should not be allowed to rise 



above 75° or 78° with air, — giving and reducing the latter
