Pàgina 129 - England than a scarcity of fertilisers — it means a scarcity of food. It is impossible that such a sinful violation of the divine laws of Nature should for ever remain unpunished ; and the time will probably come for England sooner than for any other country, when, with all her wealth in gold, iron, and coal, she will be unable to buy one-thousandth part of the food which she has, during hundreds of years, thrown recklessly away.
