DRAKE, it is still commonly supposed, first introduced the potato into England, or was it John Hawkins ? Or was it the returned colonists whom Drake had sent to America ? And was it, indeed, not England at all but Ireland that first knew the joys of potato-eating ? These are dark mysteries, and perhaps Dr. Salaman this evening will elucidate them. For the potato has an ancient and worthy history, and one highly interesting to follow.
