   “The Lumper, as they call this particular variety of pots, is a symbol of this Irish dilemma, for this is the infamous potato that failed in the 1840s and caused the great famine. The Lumper is therefore one of the most historic of all the heirloom potato varieties now preserved under the careful eye of historic museums and potato enthusiasts alike, myself included.”

   “In the 1840s, however, these two counties were among the worst affected when Ireland's potatoes -- those big floury Lumpers that sustained millions -- began to rot.”
