156 CHRYSANTHEMUMS 



they should be removed and burned immedi- 

 ately, and if a plant becomes badly infected 

 it should be burned. In whatever manner 

 the plants are cultivated, whether indoors or 

 outdoors, endeavour to keep the dew and 

 moisture off the foliage as much as possible." 

 This last admonition by Professor Stone, 

 while being excellent advice upon the subject 

 in question, needs to be qualified. It is, in 

 fact, incompatible with the instructions 

 given for the prevention and eradication of 

 insects, unless qualified. Water maybe used 

 freely upon the foliage of the plants, provided 

 that the soil is not kept saturated at any 

 time and the foliage is perfectly dry before 

 sunset each day, and during cloudy and wet 

 weather. The soil should also be kept 

 reasonably dry during periods of cold, cloudy, 

 and rainy weather. If these conditions are 

 maintained, water may be used liberally on 

 the foliage without danger of inducing fun- 

 gous diseases, for in our climate a liberal use 

 of water on the foliage is absolutely necessary 

 to the development of good chrysanthemums. 

 With a thorough understanding of the mat- 

 ter, the advice of Professor Stone is excellent, 

 and entirely consistent with good practice.
