The annexed figures will show what portions of some of the above articles were received from Canada during the same period:

Of the above amount of 4,231,899 bushels of wheat, only 1,676,213 were forwarded by canal; and, while there were received by lake only 389,929 barrels of flour, there were forwarded by canal 888,131 barrels, showing that of the remaining 2,555,686 bushels of wheat there were manufactured by the Oswego mills and sent forward by canal, 498,200 barrels of flour, while probably 13,000 barrels of flour in addition were absorbed by local consumption.

According to this calculation, the capacity of the Oswego flouring mills cannot fall short of 511,000 barrels of flour per annum. The value of the Canadian commerce of this district is estimated, for 1851, as follows:

Imports paying duty..

Imports bonded and free.

Total foreign imports..

$435,153 1,349,259

1,784,412

This, it should be observed, amounts to very nearly one-half the entire Canadian commerce with the United States. Owing to the large proportion of Canadian produce entered in bond, the amount of duties collected is comparatively small, when contrasted with that received in other districts; but this fact renders the trade none the less valuable to Oswego.

The whole amount of duties collected in Oswego, in 1851, was $89,760, while there was assessed and secured on the property entered in bond the further sum of $226,937, making a total of $356,697 duties assessed on property entered at the port of Oswego during the year.
