Hodgon's map of the Philippines Islands.

A very rare and important map of the Philippine Islands prepared by Caspar W. Hodgson and engraved by A. Briesemeister. The map measuring unfolded more than 1,4 x 1meters was lithographed in colors by the most famous lithography company in USA at the time: A. Hoen & Co. of Baltimore.
On December 10, 1898 the Treaty of Paris officially ended the Spanish-American War. The United States took over much of Spain’s overseas holdings and the Philippines were bought by the United States for $20 million.

In 1906 Casper W. Hodgson prepared a very detailed map of the Philippine Islands according to the Treaty of Paris, showing islands, provinces, municipalities, townships, municipal districts and barrios in the Philippine Islands.
The map shows the Treaty of Paris limits in a dotted line in the China sea.
In upper left corner inset with Bantan Island and Babuyan Islands" (255x170mm.). In lower left inset of Sibuta Passage.

The map includes to the left a horizontal line composed of dots and dashes along the 118° longitude line.
Annotated as "PARIS TREATY LINE", it concurs with the line established in Treaty of Paris, which is the western boundary of the Philippines according to the treaty.
Scarborough Shoal (now Huangyan Dao) lies beyond the line, indicating that the initial naming of Huangyan Dao by the British in the 18th century was restored and the Spanish name of the 19th century was abolished.
