The iconic Saturday Evening Post is an American magazine that (aside from folding for two years before relaunching in 1971) has been running since 1821!
The magazine contains general human-interest type articles, and in the September 1958 issue Peterborough was featured. In an article entitled "Wonderful Waterways", the author describes his visit to our magnificent Lift Lock.
This is how the article described it...
"At Peterborough, Ontario, the author's boat enters one of the world's highest hydraulic lift locks. Like a huge chemist's scale, the lock raises and lowers vessels in 'pans' of water."
Norman Rockwell’s famous painting The Runaway, was the cover of this issue that featured the Lift Lock.
