A canal pound is the stretch of level water impounded between two canal locks. Canal pounds can vary in length from the non-existent, where two or more immediately adjacent locks form a lock staircase, to many miles.
A specific type of canal pound is the summit pound, which is formed at a summit on the canal, and where both the defining locks descend from the summit pounds. Summit pounds are particularly important in canal design, as every boat entering or leaving the pound results in a loss of water. Summit pounds therefore need an independent form of water supply, which may take the form of weirs on adjacent rivers, reservoirs or pumping stations.
To assist in the construction of the canal, a young man named Orange Dibble invented a horse operated crane that could lower a wooden bucket to the bottom of the cut and when it was filled with rock it could be lifted to the bank above.
In the summer of 1823, the canal east of the locks opened for navigation and goods were then portaged around the locks.
The average canal tows were single, one boat to one horse or mule.
Fishing is done in a river, canal, lake, sea or ocean, from the shore or from a boat or ship (or occasionally, as in the picture, standing in the water).
Recreational fishing is generally done with a pole (fishing rod) and line with a small number of hooks, a technique known as angling.
The next day salt it with two ounces of salt and a quarter of an ounce of saltpeter to the pound of roe.
