Remarkable large format working sea chart of Australia and New Zealand, published by James Imray.
The present map was used on a voyage to Australia by the American Clipper Ship Boston Light. Annotations include a line leaving Port Jackson and noting " Boston Light for Hong Kong August 1855" at the upper left.
The Daily Alta California of April 28, 1855 and May 1, 1855 advertised that the Boston Light, commanded by William Collagan, "Having one-half of her cargo positively engaged," will sail as above (For Melbourne or Sydney) on or before May 10, 1855. The ship sailed from San Francisco to Sydney, arriving July 20, 1855. The Sydney Morning Herald of August 20, 1855 and August 21, 1855 noted the Boston Light departing for Hong Kong in its list of Projected Departures. The inset also shows evidence of being used for navigation through the Bass Strait.
This fine chart, including inset plans of Bass Straits and Port Philip, is one of the largest sea format sea charts of the whole of Australia to have been published for commercial use at sea.
OCLC locates only a single example of this map (British Library). We locate on line the example of the Royal Museums Greenwich, but no example in any Australian institutional collection was noted.
