TRADE, COMMERCE, AND THE FISHERIES. - The treaty of 1814 did not end our troubles with Great Britain. Our ships were still shut out of her West Indian ports. The fort at Astoria, near the mouth of the Columbia River, had been seized during the war and for a time was not returned as the treaty required. The authorities in Nova Scotia claimed that we no longer had a right to fish in British waters, and seized our fishing vessels or drove them from the fishing grounds. We had no trade treaty with Great Britain.
