The great Irish Famine, which reached its height in 1847, was, in many of its features, the most striking and most deplorable known to history. The deaths resulting from it, and the emigration which it caused, were so vast, that, at one time, it seemed as if America and the grave were about to absorb the whole population of this country between them. The cause of the calamity was almost as wonderful as the result. It arose from the failure of a root which, by degrees, had become the staple food of the whole working population: a root which, on its first introduction, was received by philanthropists and economists with joy, as a certain protection against that scarcity which sometimes resulted from short harvests. Mr. Buckland, a Somersetshire gentleman, sent in 1662 a letter to the Royal Society, recommending the planting of potatoes in all parts of the kingdom, _to prevent famine_, for which he received the thanks of that learned body; and Evelyn, the well-known author of "The Sylva," was requested to mention the proposal at the end of that work.
