CALENDAR OF OPERATION'S. 189 



next beginning to color. Water overliead ought to bo 

 discontinued in the latter, and entirely withheld in the 

 former. Keep the house well aired, by opening both 

 the top and front ventilators. Let the ailing be more or 

 less abundant, according to the weather, ventilating 

 freely when clear and warm, and closing the house when 

 stormy and cool. As much as possible maintain a free 

 circulation ; for, if the grapes become covered with con- 

 densed moisture the flavor is very much deteriorated, 

 besides being liable to rot. If wasps or flies become 

 troublesome, hang up vials partially tilled with molasses 

 and honey mixed together, or some sugar dissolved in 

 water, Avith the addition of a small portion of rum. 

 Either of these mixtures will entice them to enter the 

 vessel, and both will destroy; the first by its adhesive 

 consistency, and the second by its stupifying effects, 

 causing the insects to fall into it, where they are 

 drowned. 



RETARDING HOUSE. 



This house may now be closed in the evening, and 

 kept cool during the day, which may be accomplished 

 by lowering the top ventilators far down. Do not open 

 ihe front windows at all when cloudy, and no further 

 at any time than is actually necessary to reduce tlie heat 

 to 75 deg. at noon. When the weather is settled and 

 dry, an occasional syi'inging in the evening may be ap- 

 }>lied, but this must be done with caution, on account of 

 the liability to mildew ; for this crop is more commonly 

 attacked than any other. This affection does not often 

 ai)p<'ar until next month, and ^ull be fully discussed at 

 ihiit UQie.
