BRITISH GUIANA The only British possession in South America was formally ceded in 1814-1815. Three colonies were in 1831 consolidated into one, divided into three counties, Berbice from Corentyn river to Abary creek, Dernerara from Abary to Boerasirie creek, Essequibo from the Boerasirie to the Venezuelan frontier. This boundary-line with Venezuela long remained in dispute. The Dutch, while British Guiana was theirs, claimed the whole water shed of the Essequibo river, while the Venezuelans said the Spanish province of Guayana had extended to the Essequibo. In 1840 Sir Robert Schomburgk suggested the "Schomburgk line"; and later, though no agreement was arrived at, modifica tions were made. In 1886 Great Britain located outposts at points along "the modified Schomburgk line" and for some years Guiana police and Venezuelan soldiers faced one another across Amacura creek in the Orinoco mouth and at Yuruan up the Cuyuni river. After a presidential message to the Congress of the U.S.A. (1897) an international commission made its award at Paris in 1899 (see VENEZUELA). Neither party gained its extreme claim, the line laid down differing but little from the original Schomburgk line. Demarcation by a joint commission (Venezuela and British Guiana) was completed in 1904. Owing to the impassability of the country, the commissioners suggested a deviation to follow the watersheds of the Caroni, Cuyuni and Mazaruni rivers and the two governments agreed. In 1902 the delimitation of the boundary between British Guiana and Brazil was referred to the arbitration of the king of Italy, who in June 1904, awarded most of the area in dispute to British Guiana. The demarcation has since been carried out. The present area is 89,48o sq. miles.
West to east are the Pacaraima and Merume Mts., and the lesser Kanuku Mts. (2,000f t. ), while the Acarahy Mts., densely wooded (2,5ooft.), form the southern boundary and the water shed between the Essequibo and Amazon. The mountains rise in terraces and broad plateaus, with steep sandstone scarps. They are mostly flat-topped, and their average height is about 3,5ooft. The Pacaraima Mts. reach 8,635ft. at Roraima, which springs as a wall of red rock i,5ooft. high out of forest-clad slopes; in December 1884 Messrs. im Thurn and Perkins found a ledge by which to reach the summit, a table-land some i 2sq.m. Mt. Kukenaam, of similar structure rises above 8,5ooft. Other conspicuous summits (about 7,000ft.) are Iwalkarima, Eluwarima, Ilutipu and Waiakapiapu. The southern part of the Pacaraima range comprises rugged hills and rock-strdwn valleys, but to the north where the sandstone assumes the table-shaped form there are dense forests, and waterfalls may descend nearly 2,000f t. sheer, as at Roraima and Kukenaam. Long ranges of hills 2,000 up to 3,000f t., traversing the gneissose plains are either old intrusions of diabase and gabbro or later ones of dolerite. The rocks of these ranges are the main source of gold in British Guiana.

Government and Administration.—Executive power is vested in a governor advised by an executive council. Legisla tive authority was until July 18, 1928 vested in the Court of , Policy consisting of the governor who presided and without whose permission no legislation could be initiated, seven other official members and eight elected members. This body had, however, no financial authority, all taxation and expenditure being dealt with by the Combined Court, consisting of the Court of Policy with six financial representatives. In 1927 a Parliamentary corn mission was appointed to report on the economic condition of the colony and recommended certain constitutional changes. These recommendations were subsequently adopted by the Home Government and promulgated by an order in council which super seded the old Court of Policy and the Combined Court by a Legislative Council consisting of the governor as president, ten official members and 19 unofficial members. The (male) franchise is based upon certain small property qualifications. The Roman Dutch law, modified by orders-in-council and local statutes, gov erns actions in the civil courts, but the criminal law is founded on that of England. The Church of England and the Church of Scotland are both established, and grants-in-aid are also given to the Roman Catholic and Wesleyan Churches and to several other denominations. The revenue and expenditure now each amount annually to an average of a little over LI,000,000. About one-half of the revenue is produced by import duties, and about one-fifth by excise. The public debt on December 31, 1926, stood at L2,70I,126.
Education.—The system of primary education is denomina tional and is mainly supported from the general revenue. Sec ondary education is privately provided in Georgetown and Berbice, aided by government grants, and given for boys at Queen's college, an undenominational government institution where the course of instruction is the same as at a public school in England. The Guiana scholarship, open to boys and girls, carries a university or professional training in England.
Industries and Trade.—The principal exports are sugar, rum, molasses, molascuit—a cattle food made from molasses— rice, timber, coconuts, balata, bannik, diamonds and gold. The value of the total exports was L3,130,706 in 1925 of which three fourths went to Great Britain and British possessions. The cultiva tion of rice has made great strides in recent years. In 1873, 32,000,000 lb. of rice were imported, whereas in 1925, 15,496,205 lb. were exported, principally to the British West Indies. The cul tivation of the sugar-cane and its manufacture into sugar and its by-products still remains, in spite of numerous fluctuations the principal industry. Production has been greatly economized by the grouping of exports about central factories. Most of the sugar exported now goes to Canada, most of the rum to England and most of the molasses to Holland and Portuguese possessions. The lands on the coast and on the river banks up to the sand hills are of great fertility. The problem of agricultural develop ment, however, is one of great difficulty. Much of the privately owned land is not beneficially occupied, and though there are vast tracts of uncultivated Crown land where a farm can be easily and cheaply acquired, the difficulties involved in clearing, draining and in some cases protecting it by dams are almost prohibitive.
Prospecting for gold began in 188o, and from 1884 to 1893 1894 the output, chiefly from alluvial workings, increased from 25o oz. to nearly 140,000 oz. annually. It has now fallen to about 6,000 oz. Diamonds to the value of L686,900 were exported in 1926. Bauxite (aluminium ore) £170,850.
Timber (export value 1925, L31,608) is cut, and balata (L113, 112) and rubber collected from Crown lands by licences issued from the department of lands and mines. An efficient forest department newly created is making a survey of the forest re sources. The value of imports was L2,908,434 in 1925, of which nearly three-fourths were from Great Britain and British pos sessions. Of the vessels trading with the colony, most are under the British flag, the remainder being principally American and Norwegian.
The money of account is dollars and cents, but, with the ex ception of the notes of the two local banks, the currency is British sterling. The unit of land measure is the Rhynland rood, roughly equal to 12 feet 4 inches. A Rhynland acre contains 300 square roods.
