Africa also furnish good rubber, as do the Forsteronia gracilis of British Guiana and Forsteronia floribunda of Jamaica.
Some prominent examples (dealt with elsewhere under their appropriate titles) are the dispute between the United States and Great Britain respecting the " Alabama " and other vessels employed by the Confederate government during the American Civil War (award in 1872); that between the same powers respecting the fur-seal fishery in Bering Sea (award in 1893); that between Great Britain and Venezuela respecting the boundary of British Guiana (award in 1899); that between Great Britain, the United States and Portugal respecting the Delagoa railway (award in 1900); that between Great Britain and the United States respecting the boundary of Alaska (award in 1903).
A still more interesting boundary dispute was that between Great Britain and Brazil, as to the southern frontier line of British Guiana.
The question was a complicated one involving the historical survey of Dutch and Portuguese exploration and control in the far interior of Guiana during two centuries; and it was not until 1904 that the king of Italy gave his award, which was largely in favour of the British claim, and grants to British Guiana access to the northern affluents of the Amazon.
The boundary dispute with British Guiana was settled in October 1899 by an arbitration court in Paris.
