What is agricultural revolution?

Famous quotes containing the word revolution:

“History in the making is a very uncertain thing. It might be better to wait till the South American republic has got through with its twenty-fifth revolution before reading much about it. When it is over, some one whose business it is, will be sure to give you in a digested form all that it concerns you to know, and save you trouble, confusion, and time. If you will follow this plan, you will be surprised to find how new and fresh your interest in what you read will become.”
—Anna C. Brackett (1836–1911)
