Intelligence and Miscellanies. 313 



If the drawing and description furnished by Captain Hall, 

 (clear and intelligible as they are,) should leave any thing to 

 be desired, to a perfect understanding of the subject, especially 

 by those not familiar with ships, the Editor will have great 

 pleasure in exhibiting and explaining the model, furnished by 

 Capt. Marshall. It renders the invention and its application, 

 perfectly intelligible, even to mere landsmen. 



2. Miscellaneous notices among the White Mountains and 

 other places, by Prof. F. Hall. 



TO PROFESSOR SILLIMAN. 



Sir — If the following localities have not been made public 

 by yourself, or some other individual, I will thank you to in- 

 sert a notice of them in the " American Journal of Science 

 and Arts." F. Hall.. 



Beryls occur at Fryeburg, Maine, a few rods from the vil- 

 lage, in great abundance and variety. Some of them are 

 four or five inches in length, and from one tenth of an inch, to 

 two inches in diameter. They exhibit the usual color, and 

 form, and articulations of the beryl. This information is de-

 beautiful specimens of the mineral, which he had procured 

 fron this locality. 



Permit me, Sir, to remark, that in whatever part of our 

 country I travel, I find enterprising and enlightened mineral- 

 ogists. Twenty-five years have not yet fully elapsed, since 

 total darkness, in relation to mineralogy, brooded over our 

 whole land. Now, light is springing up, and diffusing itself, 

 in every direction. Much of this light has unquestionably, 

 been produced by the lectures* given in Yale College, by 

 the publications from that seminary, and from Professor 

 Cleaveland ; much by the exertions of that excellent man, 

 Dr. Bruce, who now rests from his labors, and much by those 

 of that able geologist, William Maclure, the actual President 

 of the American Geological Society. The gentleman last 



* If Prof. Hall thinks the efforts that have been made in Yale College, at all 

 importamt to he mentioned on the present occasion, he would not, we presume, 

 omit to honor the zealous and successful exertions of Dr. J. W. Webster, and 

 Dr. H. H. Hayden, nor the early labors of Dr. Seybert and Dr. Mitchill, and 

 the cabinets formed by, or under the auspices of, the late B. D. Perkins, Mr. 

 Gilmor, the late Dr. Smith, (of Philadelphia,) Dr. Hosack, and Dr. Water- 

 house, and more recently, by many other gentlemen. . -
