Rocky Mountains (Brig), 20 Jul 1837

Green Bay. April 21. A large hermaphrodite brig, which has been on the stocks, at this place for some time past, is now nearly finished, and will be ready for launching early in the season of navigation -- affording one more evidence of the enterprize of our merchants and of our superior home facilities for the building of vessels Beauty and strength. judging from present appearances, will be its characteristics, and we think it will not suffer in comparison with any vessel on the lakes. The length of her keel is eighty five feet; deck, one hundred and five feet; beam, twenty-eight and a half feet and hold, nine and a half feet. She is to have six state rooms, three berths each -- eight double berths in the ladies cabin and calculated to carry thirty-two cabin passengers. She is a vessel of 265 tons burden, and destined exclusively for commerce between Green Bay and Buffalo. -- Wisconsin Dem
