has recently sent to this market % tuns copper,

During the winter Company, Of which Thomas
Adds Emmett, Esq is President, has been working
lead vein in st. Lawrence County, N. Y, %

1000 feet apart on the vein, which improves ashley
descend. The appearance of the vein az at present
exposed indicates that an immense amount of lead

Ogdensbureh al $9Ca$l00 per tun.
From Virginia we hear favorable reports OF the
gold workings There are but few Companies en-
gagged in this business, but individual enterprise has
oeen well rewarded within the last year. We have
verbal reports from dozen workings, all which
have been profitable, although there has been
no'hirg very brilliant in the results.
TIE adyices from California in relation to Quartz
continue to be encouraging. We have always be.
lieved that Quartz mining in California, with good
machinery and under prudent management, must
produce large profits The surface washings mus be-
fore long be exhausted, while vein mining appears
10 be almost unlimited in extent Several new COM

the Inve sment of capital in these apparently highly
profitable enterprises. The Rocdy Bar was the first
