_American Canals._

The canals are the most striking internal improvements in the United
States. The Great Erie canal is 360 miles in length, with an average
breadth of 40 feet. It connects the great line of lakes with the ocean
by the Hudson. Another to connect the Hudson with Lake Champlain is also
complete. Above 2,000,000_l._ have been expended on them; and the
annual returns from the tolls alone have already amounted to
120,000_l._ In the state of Ohio, another canal is in progress,
almost equal in magnitude to the Erie canal. On the rivers which it
connects with the lakes, there is a steam-boat navigation of 5,000
miles. In Pennsylvania, the Schuylkill navigation works comprise an
extent of 108 miles, of which 62 are canal, and 46 the river made
navigable. These works are complete. The Union canal, a line of 74
miles, to connect the Schuylkill with the Susqueannah, is in progress,
and will be completed within the present year. These, however, are but a
few of the gigantic strides which America is making in the march of
nations.


_Caledonian Canal._

Between August 1, 1826, and August 1, 1827, 212 vessels have passed
through the Caledonian canal from sea to sea. 295 vessels have made
partial passages through one end of the canal, to and from various
ports; 74 boats, not above 15 tons burden each, have been employed in
