(1851). In May, 1850, a fugitive slave from Virginia, named Frederic Wilkins, came to Boston, and secured employment under the alias of Shadrach. Subsequently he was arrested and jailed in the United States Court-house pending trial. Shadrach was rescued by a body of colored people and conveyed in safety to Canada. Intense excitement prevailed in Boston, and spread over the entire country upon Congress turning its attention to the infringement of the law. Mr. Clay introduced a resolution requesting the President to send to Congress information regarding the matter. President Pierce issued a proclamation announcing the facts, and calling upon the people to prevent future disturbances.
