Fumigation. Destroying aphides and thrips by means of tobacco smoke, and various 

 preparations that give out fumes, comprises fumigation. Manufactured tobacco, through 

 its costliness, is little used. The usual fumigating material consists of brown paper or 

 rag steeped in the juice of tobacco obtained in manufacture, dried, and stored in a dry 

 place to prevent mould and loss of narcotic value. Some tobacco papers and rags con- 

 tain ingredients injurious to vegetation. Those containing sufficient sulphur to destroy 

 mildew and red spider, must be used with great care in fruit houses. One dose of such 

 mixture may cause the loss of a year's crop of fruit, and prejudice the succeeding one by 

 loss of foliage. An overdose of any mixture may have a similar effect. Therefore, the 

 best material only ought to be employed, and this should be used in moderation, more 

 as preventive of attacks by insects than for their destruction. 



Dull weather is the best for fumigation, when there is moisture on the glass and in 

 the laps of the panes, to prevent the smoke escaping, while the fumes remain longer 

 about the trees, through the house not being so much opened as in fine weather. The 

 weather must be calm, and every possible means adopted to retain the smoke in the 

 house by stopping up any bad- fitting joints with old newspapers, and covering the glass 

 with blinds or mats. This will save fumigating material, and occasion less need of a 

 dangerous dose. The foliage must be dry. When fumigation is contemplated in the 

 evening, syringing during the day should be dispensed with, otherwise moisture may 

 rest on the foliage and cause its scorching. It is well to avoid closing the house in 

 advance of fumigating. Peach-houses closed early and damped, but the trees not
