and even ladies not unfrequently enter this cavity, and find 

 themselves amply repaid for their trouble.* 



2. Vein of Galena in JVliately, 



This occurs in the north west part of the town, and I for- 

 merly supposed it a continuation of the Southampton vein. 

 B'jf the Southampton vein runs north east and south west, 

 and this in Whately almost exactly north and south. Be- 

 sides the Southampton vein must turn almost at right angles 

 from Hatfield, in order to be found in the north west part of 

 Whately. 



This vein may be traced at intervals one hundred rods, 

 and extends into tlie edge of Conway. At the extremities 

 it traverses mica slate ; but in the middle, it cuts through an 

 extensive bed of granite. Its diameter is usually six or sev- 

 en feet, and the gangue is wholly common and radiated 

 quartz. Galena, which is the only ore found in this vein, 

 is disseminated through this matrix in considerable abun- 

 dance. Very few efforts have been made to explore this 

 vein, though appearances at the surface are not unfavora- 

 ble ; and if a horizontal drift were necessary, a deep valley 

 within a few rods on the west, would afford a favourable op- 

 portunity for making it. As nearly as I could determine, this 

 vein is not far from perpendicular to the horizon. 



3. Vein of Galena in Leverett. 



In the south west part of the town — traversing granite — - 

 only a foot wide — gangue, sulphate of barytes — deviation 

 north and south — galena the only ore. 



4 Vein of Galena, Pyritous Copper and Blende, in Leverett. 



About two miles north of the vein last mentioned; and it 

 may be a continuation of it. The gangue is quartz, united 

 witi) sulphate of barytes ; and the galena and pyritous cop- 

 per are disseminated through it in nearly equal quantities. 



* I have often thought Professor Cleave land must have selected the ap- 

 propriate motto prefixed to his Miiieraloiry, whea entering this or JOtne
