RODRIGUEZ (officially RODRIGUES) , an See also:island in the See also:Indian Ocean in 19° 41' S., 63° 23' E.; the most important dependency of the See also:British See also:colony of See also:Mauritius, from which it is distant 344 nautical See also:miles. It is a station on the " all-British " See also:cable route between See also:South See also:Africa and See also:Australia, telegraphic communication with Mauritius being established in 1902. With a length of 13 M. E. and W., and a breadth of 3 to 6 m. N. and S., it has an See also:area estimated at 422 sq. m. On all sides it is surrounded by a fringing See also:reef of See also:coral, studded with islets. This reef, only Too yds. wide at the eastern end of the island, extends westward 3 m., and both N. and S. forms a See also:flat area partly dry at See also:low See also:water. Two passages through the reef are available for large vessels—these leading respectively to See also:Port Mathurin on the N. See also:coast and to Port South-See also:East. The island was at one See also:period believed to consist of See also:granite over-laid with See also:limestone and other See also:modern formations, and its supposed formation caused it to be regarded as a remnant of the hypothetical See also:continent of Lemuria. The investigations made by an expedition sent by the British See also:government in 1874 showed, however, that the island is a See also:mass of volcanic See also:rock, mainly a doleritic See also:lava, See also:rich in See also:olivine. The See also:land consists largely of a See also:series of hills. The See also:main See also:ridge, which runs parallel to the longest See also:diameter, rises abruptly on the east, more gradually on the See also:west, where there is a wide See also:plain of coralline limestone, studded with caves, some stalactitic.

Of several peaks on the main ridge the highest is Mt. See also:

Limon, 1300 ft. above the See also:sea. The ridge is deeply cut by ravines, the upper parts of which show successive belts of lava separated by thin beds of cinders, See also:agglomerate and coloured See also:clays. In places the cliffs rise 300 ft. and exhibit twelve distinct lava flows. The See also:climate is like that of Mauritius, but Rodriguez is more subject than Mauritius to hurricanes during the See also:north-west See also:monsoon (See also:November to See also:April). See also:Flora and See also:Fauna.—When discovered, and down into the 17th See also:century, Rodriguez was clothed with See also:fine See also:timber trees; but goats, See also:cattle and See also:bush-fires have combined to destroy the See also:great bulk of the old vegetation, and the indigenous See also:plants have in many cases been ousted by intrusive foreigners. Parts are, however, still well wooded, and elsewhere there is excellent pasturage. The' sweet See also:potato, manioc, See also:maize, See also:millet, the See also:sugar-See also:cane, See also:cotton, See also:coffee and See also:rice grow well. See also:Tobacco is also cultivated. See also:Wheat is seldom seen, mainly because of the parakeets and the See also:Java sparrows. Beans (Phaseolus lunatus), lentils, See also:gram (Cicer arietinum), dholl (Cajanus indicus) and ground-nuts are all grown to a certain extent in spite of ravages by rats. Mangoes, bananas, guavas, See also:pine-apples, custard-apples, and especially oranges, citrons and limes flourish.

Of the timber trees the most See also:

common are Elaeodendron orientate, much used in See also:carpentry and for pirouges, and Latania Verschaffelti (Leguat's plantane). At least two See also:species of See also:screw-pine (Pandanus heterocarpus, Balf. See also:fit., and P. tenuifolius) occur freely throughout the island. The See also:total number of known species, according to See also:Professor I. B. See also:Balfour, is 470, belonging to 85 families and 293 genera. The families represented by the greatest number of species are Gramineae, See also:Leguminosae, See also:Convolvulaceae, See also:Malvaceae, See also:Rubiaceae, See also:Cyperaceae, See also:Euphorbiaceae, See also:Liliaceae, See also:Compositae. Mathurina penduliflora (Turneraceae) is interesting, as its nearest congener is in Central See also:America. Of 33 species of mosses 17 are See also:peculiar. Variability of species and heterophylly are characteristic of the flora to quite an unusual degree. At See also:present the only indigenous mammal is a species of See also:fruit-eating See also:bat (Pteropus rodericensis), and the introduced species are See also:familiar creatures as See also:deer, See also:pig, See also:rabbit, See also:rat, See also:mouse, &c.; but down to a See also:recent period the island was the See also:home of a very large land-See also:tortoise (Testudo Vosmaeri or rodericensis), and its limestone caves have yielded a large number of skeletons of the See also:dodo-like See also:solitaire (Pezophaps salitarius), which still built its See also:mound-like See also:nest in the island in the See also:close of the 17th century, but is now See also:extinct (see Donis). Deer, once plentiful, had become very scarce by the beginning of the 20th century, having been indiscriminately hunted by the inhabitants. Of indigenous birds 13 species have been registered.

The See also:

guinea-See also:fowl (introduced) has become exceedingly abundant, partly owing to a protective See also:game-See also:law; and a francolin (F. ponticerianus), popularly a " See also:partridge," is also common.
