Whatever may have been his culture, occupation, character, or social position, he assumed the responsibility of what is imputed to him--and we very willingly leave uncontested both his claims to have been author of all that he subscribed to, and to be called a Boston _merchant_. Calef went into his work in deep earnest, and perhaps from a strong sense of duty to God and man; he perceived that departure from teachings and requirements of the Scriptures, and adoption of opinions, processes of examination, and kinds of evidence which the Scriptures did not prescribe, had occasioned the chief woes of witchcraft, and therefore devoted much time to the work of producing great and needed change in public opinion. He continued for some time to write clearly and forcibly to Mather; but, failing there to get his fundamental questions squarely and satisfactorily met, after months of trial, addressed a letter "to the ministers, whether English, French, or Dutch," upon this subject; this general application, however, failed to bring a response. Next he tried the Rev. Samuel Willard individually, then "all the ministers in and near Boston;" afterward Rev. Benjamin Wadsworth singly; but his success in eliciting replies was so meager, that we apparently may apply to those from whom he sought information the following words which he used in reference to some who had defined rules by which to detect witchcraft,--viz., "Perhaps the force of a prevailing opinion, together with an education thereto suited, might overshadow their judgments." His dates show that his calls for either refutation or assent to his positions were continued for two or three years, and that he was not simply or mainly an opponent of Mather, but an earnest seeker for light. In 1700, his collected correspondence, together with much other matter from Mather's pen and other sources, was published in London, and entitled "_More_ wonders of the Invisible World," Mather having previously published "Wonders of the Invisible World." This clear-sighted, earnest, untiring spirit soon gained the public ear extensively, began to enlighten the public mind, and turn it into new channels of thought and inquiry. Though not a polished, he was an intelligible, logical, and forceful writer in the main, and did much toward accomplishing the reformation to which he devoted his energies. Calef was a moral hero, and bravely did noble work in bringing flood tides of murderous fanaticism, error, and delusion to an ebb, and in barring channels against their return. His appropriate stand in history's niches may be at the head of Witchcraft Reformers--not repudiators, but _Reformers_. THOMAS HUTCHINSON.
