Broughton’s patent stoves, the making of which constitutes 
the chief business of the establishment, are in so much de- 
mand, that they are disposed of as fast as they can be man- 
ufactured. At the forge, the ore is fused, without the addi- 
tion of any foreign article for a flux. At the furnace, sili- 
cious limestone is employed for this purpose. 
In the single county of Rutland, there are no less than 
four blast furnaces, and two or three pocket furnaces, as 
they are called, all in successful operation during a consid- 
erable part of each year. 
I have just received a mineral from a gentleman at Mon- 
treal, which, if I mistake not, is awgite imbedded in schthy- 
ophthalmite. The latter substance is less brilliant, than a 
specimen [ have from Sweden, but possesses most of its 
characters. The augite is green, and occurs in large imper- 
fect crystals. The mineral was found at Long Sault on the 
Ottawa river, about seventy miles above Montreal. 
Amianthus occurs, at Barton, Vt. Its fibres are white 
and remarkably delicate. Common and ligniforin asbestus 
is foundin vast quantity, in Mount Holly, Vt.

With sentiments of high respect, 
Your very obedient,

1 -—Notice of some minerals from the New South Shetland 
Islands. 
Tue arrival of a vessel, from the New South Shetland 
Islands, at this port, afforded me an opportunity of examin- 
ing many interesting specimens of the minerals of those 
islands. From the general character of these substances, 
and from the close resemblance they bear to some of the 
mineral productions of Iceland and the Ferroe Islands, | am 
induced to think that the geological structure of the New 
South Shetland Islands, is similar to that of the two former,
