In Enlightenment Now, Harvard University professor Steven Pinker recounts how farm technology helped get boys off the farm and into classrooms.
This ad from 1921 reads: "“By investing in a Case Tractor and Ground Detour Plow and Harrow outfit now, your boy can get his schooling without interruption, and the Spring work will not suffer by his absence. Keep the boy in school—and let a Case Kerosene Tractor take his place in the field. You'll never regret either investment.”
What's this have to do with dogs? More than you might think! As I noted some time back in a post entitled Man, Mule, Mutt, and Machine:
With an explosion of farm tractors and trucks in the 1930s, 40s, and 50s, a glut of old farm horses and mules appeared on the market. The horse and the mule, once an essential means of production, was now a nearly-useless vestige of another area consuming too much pasture, money, and time.
The solution? Canned dog food.
