CALENDAR OF OPERATIONS. T03 



entirely destroy the mildew, while the introduction of 

 any preventive in a liquid state is, to say the least, of a 

 doubtful utility ; all such, which I have known, ojily in- 

 crease the evil. See that tlie outside borders are well 

 mulched, if not already attended to ; and should there be 

 drouth, a good soaking of water, in which is dissolved 

 one pound of guano to thirty gallons ; or, still better, the 

 diluted drainings of a dung-hill will be of material ser- 

 vice. As the berries progress in size, lose no time in 

 commencing to cut out the superfluous ones, according 

 to previous directions, and when it is desired to retain 

 them upon the vines after becoming ripe, reduce the 

 quantity of berries so that they may hang loosely, and 

 the air be enabled to circulate through the bunches. 



FORCING-HOUSE. 



The only care required hereafter in this department 

 will be the eradication of insects, and shortening-in the 

 extra growth. Let the house remain open at all times, 

 excepting during storms, to preserve the fruit, and pre- 

 vent the vines from pushing a second growth, which 

 would seriously injure them for another season. 



RETARDING-HOUSE. 



The same treatment recorded for the Cold Grapery 

 last month will now apply to this, excepting that the 

 thermometer may range some five degrees lower at mid- 

 day, and great care should be exercised in using water. 

 If mildew shows itself, keep the house dry, apply the 

 sulphur, and employ the heating apparatus just suflicicnt 

 to rarify the air. Lift the upper ventilators at the same 

 time to reduce the temperature.
