sAnaerioan Sitk.--The article of rap

 silk, as one of export fron, this country,

 having attracted much attention, since

 the publication of Mir. Du Ponceau on

 this subject, the following facts, taken principally from the work of Count Dan-

 dolo, may not be deemed uninteresting.

 They show that there is no production, mot excepting cotton or sugar, which yields so great profit as raw silk. A plantationof6ye hundredmulberry trees will produce twenty thousand pounds of leaves. Twenty pounds of mulberry leaves will yield one pound and half of cocoons. The fifteen hundred pounds of cocoons thus made

 from plantation olive hundred trees, will furnish 35O pounds of raw silk; which, at the minimum price, would sell for seventee's Hundred dsaa jeyfiy eyfiy dolldrs. The reeling of silk from the cocoons is the art which we have yet to acquire.

 When establishments for this object are once formed, which would open a reg |ular market for cocoons, we agree, with Mir. Du Ponceatl, that these would be

 raised in abu'fdance, and our raw silk

 become commodity of large export Gen. 0hckson has caused the nanes of the following Officers to be erased from the Register of the the Nary ssi issi sequence of their having been engaged in the late duel near Philadelphia, in
