This month in Pit & Quarry history: June 1939

Publishing has come a long way over the last 75 years. So has the aggregates industry.

The June 1939 issue of Pit & Quarry ­– the one published 75 years ago this month –reflects the transformation both industries have made over the last three-quarters of a century remarkably well.

The magazine’s editors explored several topics in that June 1939 issue, including carbon dioxide recovery, choosing the correct type of rope and sampling for dust control. Take a look back at the cover that month and some of the advertisements in the issue by utilizing the slideshow above. Just a glimpse will show you how far the aggregates industry has come.
