 exhibits. 



Excursions. 



On May 26th and June 2nd there were excursions to the hills 

 at Corfe. The first was very informal owing to the weather being 

 doubtful, but that on June 2nd was well attended and very success- 

 ful. ^ The excursion to the Blue Pool on July 14th was in con- 

 junction with several other sections ; a report appears elsewhere 

 in this volume.
