Reading edition
According to Smeaton’s report in 1755, there were in spring tides only 3 feet 8 inches water at Pointhouse Ford. Measures were taken to deepen the river, and operations with that object were begun in 1768. Salmon abounded in the Clyde, and was so common that servants and apprentices were accustomed to stipulate that they should not have salmon for dinner more than a certain number of days in the week.
