requires thorough treatment. The tobacco stems 

 should be moistened before being used, or the 

 heat will be too much for the lettuce. Some skill 

 and discretion are necessary to determine just 

 how much to moisten them, and how to do the 

 smoking in the proper manner. On these points 

 a practical experience is the very best possible 

 teacher, although somewhat costly at times. After 

 the first of February there is but very little trouble 

 with this insect.* 



After the plants have been treated in this manner 

 they will be ready for transplanting into beds or 

 wherever required; while, if this treatment should 

 not be given them, it is quite likely they might 

 be destroyed. Occasionally, it is true, these 

 insects do not trouble a crop at all ; but it is much 

 the best policy to be on the safe side and use every 

 precaution. 



Through damp and cloudy weather the plants 

 are liable to mildew, both in the houses and in 

 frames. Although not as troublesome as insects, 

 mildew often destroys a crop. This can be 

 avoided by keeping up as high a temperature as 

 possible, while still giving plenty of air.
