urer of tliesc relics ; all that need bo done is, to send 

 to their Secretary any and all such contributions, and the 

 three-fold advantage is gained, of pleasing them, of benefit- 

 ing posterity, and clearing one's own house of what might 

 unsuitably encumber it. Let all remember these things, 

 and lot no document go to destruction, however insignificant 

 it may be in your own eyes. 



James J. H. Gregory, of Marblehead, had examined the 

 place pretty thoroughly for geological features worth men- 

 tioning here. He had found only two ledges of out-crop- 

 ping rock in the town, and this was a very peculiar circum- 

 stance. Not many places in New England could say the 

 same ; we generally are marked, all over the country, by 

 bare and craggy projecting rocks of one sort or another, 

 often in great profusion. Undoubtedly, rock might be found 

 under all this gravel, as in other places ; but at present, the 

 drift lies undisturbed and conceals them. There seems to 

 be great variety in the character of this drift ; around the 

 pond were many of the different types of granite and forty 

 of them might be collected within an hour. Ho had pro- 

 cured a good specimen of sienitic granite ; also a })iece of 

 pure sienite, from which the feldspar had been wasliod out, 

 leaving curious, iriegular markings and cavities. These 

 ribbed and worn fragments are rather common along the 

 ancient water-courses of New England, and indeed there is 

 nothing very peculiar in any the formations about here. 

 The chief point of interest is, after all, the abundance and 

 quietude of the overlying drift, so covering and hiding all 

 the ledges that only two of them anywhere appear. 



C. M. Tracy of Lynn, had noticed some plants about 

 the pond worthy of note, and some still more striking had 

 been found by others. The Pipe wort, (^Eriocauloii) vfhose 

 globular, lead-colored heads are so conspicuous along muddy
