 where the drainage of Port Erin is discharged, has,

"Shore collecting has been carried on at intervals all 

 through the year, and much knowledge gained of the 

 precise localities in which many species may be found. 



"On August 15th the buoy at the end of the breakwater 

 was brought ashore for its annual cleaning, and with the 

 assistance of Mr. C. Crossland of Clare College, Cambridge, 

 the Curator took from its flat bottom the following

 The constant care which its successful maintenance has 

 entailed has been repaid by the interest shown by the 

 visitors, and by the favourable comments of many who
