 CHAPTER VII: 



Terrestrial and meteorological influences affecting the worm 81 



Condition of soil and plant connected with the appearance of the 

 first worms, 81 The earliest worms are confined to the "low 

 lands," 81; and to luxuriant plants, 82; and to the vicinity of 

 winter shelters, 82; and to the same localities, 82 Influence of 

 wet weather on the development of the worms, 83 Severe rains 

 with gales destroy both worms and crop, 83 Late cold rains do 

 the same, 84 Frequent summer rains favor the development of 

 the worms, 84 Hot, dry weather destructive to them, 84 Artifi-
