 A systematic effort will be made next year in this direction, 

 beginning early in May. 



The lakes have been treated with copper sulphate as

 have been notably scarce during the past season. 



Great interest has been exhibited in the collections by the 

 public and by the teachers and students of the various

 Members of the staff and assistants assigned to guide duty

 them.

 far escaped serious injury is largely due to the vigilance of 

 members of the staff and employees out of working hours.

 rooms on the basement floor of the east wing have been 

 renovated and painted.

 removal of the cycads and ferns from the old range, several 

 houses of the latter were completely renovated. Most of

 structures needing attention have been repaired and painted 

 as required. One of the boilers at the propagating houses
