Numerous cases of diseased plants have been referred 

 to the Garden for examination. In some it was easy to 

 detect the cause of the trouble, while in others the cause 

 was not so evident. More cases of injury from "red 

 spider" have been called to our attention than usual. 

 The prevalence of this insect may have been in part due 

 to the unusually dry season. 



Morphological Grounds 



The morphological grounds were gone over in the spring 

 and in consultation with the Head Gardener numerous 

 additions were planned, but, owing to the rush of work 

 during the planting season, it became necessary to post- 

 pone these additions. 



Conference Meetings 



A meeting of the conference has been held on the first 

 Wednesday of each month, except in summer. The object 

 of these meetings is to give opportunity to the registered 

 students and members of the staff to offer papers and dis- 

 cussions of problems under investigation. The meetings 

 have been well attended and considerable interest has 

 been shown. A synopsis of the programme offered at 

 each meeting has been published in the Journal.
