INSECTS, DISEASES, AND REMEDIES 155

 observation we consider it very essential in 

 order to obtain plants free from rust. The 

 reason that inside culture results in less

 dews on the foliage, thus furnishing less 

 favourable opportunity for rust spores to 

 germinate and cause infection. Care should 

 also be taken to keep all unnecessary water 

 off the foliage in cultivation in the green-
