CIP Grade 7 and up Reviewed by Jack Brown Volume 14 Number 5 1986 September The Rideau Waterway is a lovely feature in Old Ontario, connecting Kingston and Ottawa by a silver chain of rivers and lakes linked by small locks and winding channels. It was built by the Royal Engineers of Great Britain as a military work of great urgency to counter a real threat of attack from the United States, and provided an alternative route for transport of stores and troops from Montreal to Kingston. The canal extends over 120 miles, with forty-seven masonry locks and many dams through what was then wilderness, but is now natural scenic beauty. It was the great engineering work of the century, but today it thrives on its history and secluded charm, offering delightful days of relaxation to visitors. Robert Legget is a civic engineer, the first Director of the division of building research of the National Research Council of Canada until his retirement in 1969. The first edition of his Rideau Waterway was published in 1955, but he has revised and updated the book, including three times as many photographs and much new information about historical figures and references to developments in the surrounding areas. The book is a lively guide for waterway boaters, and is of interest to readers keen on eastern Ontario history. Appendices and a good index make the book easy to use for quick reference.
