This report investigates the engineering and logistical considerations for the improvement and development of the harbor at Saint John, New Brunswick. Thomas H. Keefer, a prominent Canadian civil engineer, presents his findings and recommendations based on surveys and analyses of the existing conditions. The document outlines the challenges posed by the tides and currents, and proposes solutions for enhanced navigation and port functionality.

This report is a technical document likely valued by historians of Canadian infrastructure and maritime development, as well as civil engineers. Its focus on practical engineering solutions and detailed site analysis suggests it served as a foundational document for the harbor's subsequent expansion. The work provides insight into the challenges and foresight required for developing major port facilities in the 19th century.
