strong impression on me. As three of us were out one afternoon off the 

 south shore beyond the reefs fishing in about sixty fathoms, there came 

 floating past with the tide a school of jelly fishes, the common Aurelia. 

 I had before seen Aurelia almost cover the surface of the sea, but never

For use in dredging a much larger steamer (Fig. 25), the Intrepid, 

 was for a part of the time at our command in place of the Minnow. 

 This steamer was provided with a boom in front of the pilot house, 

 which much facilitated dredging operations, and the forward deck was

 This was the steamer that had been employed by Mr. Agassiz during

 mass that doubtless extended in previous times along the northern bor-

 rim. It is only on the calmest days and at lowest tide that one may 

 safely land on the plateau from which these three pinnacles, called 

 North Eocks, arise. The steamer can approach within a half or a quar- 

 ter of a mile and then must anchor, while in rowboats the collectors
