American Agriculture in the early 1990s (ebooks)
/Liberty Hyde Bailey edited 4 volumes of the Cyclopedia of American Agriculture between 1900 and 1910. It was a time when horticulture and agriculture were becoming more organized at universities and Bailey was a proponent of America as a ‘great agricultural civilization.’
The books are easily browsed on Internet Archive and the photographs clearly reflect the ‘state of the art for agriculture’ in the early 1900s when they were written. I selected two sample images from each of the 4 volumes. (click on the image to see a larger version)
