sentences:  Various charts and pilot books for North American waters were published in England beginning in 1671, but the first book of sailing directions, charts, and other information for mariners in North American waters published in North America was the "American Coast Pilot", first produced by Edmund M. Blunt in Newburyport, Massachusetts, in 1796.In 1833, Blunts son Edmund E. Blunt accepted employment with the United States Coast Survey, and this began a relationship between the Blunt family and the Coast Survey in which the Coast Survey provided hydrographic survey information to the Blunts for incorporation into the "American Coast Pilot" and the Blunts sold the Surveys charts, while the Blunts served as influential allies of the Survey in defending the Survey against its critics and lobbying for funding of the Surveys efforts.Other than providing information to the Blunts for publication in the "American Coast Pilot" and charts for them to sell, the Coast Survey relied exclusively on articles published in local newspapers to provide its information to mariners.
