ON VINERIES. 



gradually aiid with caution. Syringe all dry surfaces, and 

 keep water in the troughs, which should be cast on the 

 pipes, so that a sustaining moisture may be kept up when 

 required. 



Assuming now that the vines are in full leaf, and 

 the bunches making their appearance, the temperature 

 may be raised, and kept on dull days from 72° to 75°, 

 with a little air on, allowing it to rise, when the sun 

 is shining, to 80° or 85°, and even as high as 90°; but 

 the house must have a circulation of air, without a cold 

 draught. Sprinkle all dry surfaces on sunny days at 

 different times, as may appear necessary. In dull weather 

 there will not be so much evaporation ; and therefore so 

 much damping down, as it is generally called by gar- 

 deners, will not be needed. In wet weather, the eva- 

 porating troughs may be allowed to go dry for a few 

 days together. With careful watching, the amateur 

 will soon be able to know what to do in this respect. 

 The night temperature may now be kept from 65° to 

 68°. It should be at this at nine or ten o'clock in the 

 evening, and the thermometer should be found to stand 

 not lower than 63° about four or five o'clock next 

 morning. Begin to give air gradually as the sun becomes 

 powerful, and reduce it in the same way as the sun 

 goes down. So soon as there are signs of the vines 

 coming into flower, three or four more degrees of heat 



may be kept up both day and night, and the evaporating
