The Conquest of Bread by Peter Kropotkin

Let us now return to our city in revolt, and consider how its citizens can provide foodstuffs for themselves. How are the necessary provisions to be obtained if the nation as a whole has not accepted Communism? This is the question to be solved. Take, for example, one of the large French towns -- take the capital itself, for that matter. Paris consumes every year thousands of tons of grain, 400,000 head of oxen, 300,000 calves, 400,000 swine, and more than 2,000,000 of sheep, besides great quantities of game. This huge city devours, besides, more than 20,000,000 pounds of butter, 200,000,000 eggs, and other produce in like proportion.

It imports flour and grain from the United States and from Russia, Hungary, Italy, Egypt, and the Indies; live stock from Germany, Italy, Spain -- even Romania and Russia; and as for groceries, there is not a country in the world that it does not lay under contribution.
