 CADAMOSTO (or ), ALVISE (1432–1477), a Venetian explorer, navigator and writer, celebrated for his voyages in the Portuguese service to West Africa. In 1454 he sailed from Venice for Flanders, and, being detained by contrary winds off Cape St Vincent, was enlisted by Prince Henry the Navigator among his explorers, and given command of an expedition which sailed (22nd of March 1455) for the south. Visiting the Madeira group and the Canary Islands (of both which he gives an elaborate account, especially concerned with European colonization and native customs), and coasting the West Sahara (whose tribes, trade and trade-routes he likewise describes in detail), he arrived at the Senegal, whose lower course had already, as he tells us, been explored by the Portuguese 60 m. up. The negro lands and tribes south of the Senegal, and especially the country and people of Budomel, a friendly chief reigning about 50 m. beyond the river, are next treated with equal wealth of interesting detail, and Cadamosto thence proceeded towards the Gambia, which he ascended some distance (here also examining races, manners and customs with minute attention), but found the natives extremely hostile, and so returned direct to Portugal. Cadamosto expressly refers to the chart he kept of this voyage. At the mouth of the Gambia he records an observation of the “Southern Chariot” (Southern Cross). Next year (1456) he went out again under the patronage of Prince Henry. Doubling Cape Blanco he was driven out to sea by contrary winds, and thus made the first known discovery of the Cape Verde Islands. Having explored Boavista and Santiago, and found them uninhabited, he returned to the African mainland, and pushed on to the Gambia, Rio Grande and Geba. Returning thence to Portugal, he seems to have remained there till 1463, when he reappeared at Venice. He died in 1477.

Besides the accounts of his two voyages, Cadamosto left a narrative of Pedro de Cintra’s explorations in 1461 (or 1462) to Sierre Leone and beyond Cape Mesurado to El Mina and the Gold Coast; all these relations first appeared in the 1507 Vicenza Collection of Voyages and Travels (the Paesi novamente retrovati et novo mondo da Alberico Vesputio Florentino); they have frequently since been reprinted and translated (e.g. Ital. text in 1508, 1512, 1519, 1521, 1550 (Ramusio), &c.; Lat. version, Itinerarium Portugallensium, &c.,1508, 1532 (Grynaeus), &c.; Fr. Sensuyt le nouveau monde, &c., 1516, 1521; German, Newe unbekante Landte, &c., 1508). See also C. Schefer, Relation des voyages de Ca’ da Mosto (1895); R. H. Major, Henry the Navigator (1868), pp. 246-287; C. R. Beazley, Henry the Navigator (1895), pp. 261-288; Yule Oldham, Discovery of the Cape Verde Islands (1892), esp. pp. 4-15.

It may be noted that Antonio Uso di Mare (Antoniotto Ususmaris), the Genoese, wrote his famous letter of the 12th of December 1455 (purporting to record a meeting with the last surviving descendant of the Genoese-Indian expedition of 1291, at or near the Gambia), after accompanying Cadamosto to West Africa; see Beazley, Dawn of Modern Geography (1892), iii. 416-418.

CADASTRE (a French word from the Late Lat. capitastrum, a register of the poll-tax), a register of the real property of a country, with details of the area, the owners and the value. A “cadastral survey” is properly, therefore, one which gives such information as the Domesday Book, but the term is sometimes used loosely of the Ordnance Survey of the United Kingdom (1=2500), which is on sufficiently large a scale to give the area of every field or piece of ground.

CADDIS-FLY and CADDIS-WORM, the name given to insects with a superficial resemblance to moths, sometimes referred to the Neuroptera, sometimes to a special order, the Trichoptera, in allusion to the hairy clothing of the body and wings. Apart from this feature the Trichoptera also differ from the typical Neuroptera in the relatively simple, mostly longitudinal neuration of the wings, the absence or obsolescence of the mandibles and the semi-haustellate nature of the rest of the mouth-parts. Although caddis-flies are sometimes referred to several families, the differences between the groups are of no great importance. Hence the insects may more conveniently be regarded as constituting the single family Phryganeidae. The larvae known as caddis-worms are aquatic. The mature females lay their eggs in the water, and the newly-hatched larvae provide themselves with cases made of various particles such as grains of sand, pieces of wood or leaves stuck together with silk secreted from the salivary glands of the insect. These cases differ greatly in structure and shape. Those of Phyrganea consist of bits of twigs or leaves cut to a suitable length and laid side by side in a long spirally-coiled band, forming the wall of a subcylindrical cavity. The cavity of the tube of Helicopsyche, composed of grains of sand, is itself spirally coiled, so that the case exactly resembles a small snail-shell in shape. One species of Limnophilus uses small but entire leaves; another, the shells of the pond-snail Planorbis; another, pieces of stick arranged transversely with reference to the long axis of the tube. To admit of the free inflow and outflow of currents of water necessary for respiration, which is effected by means of filamentous abdominal tracheal gills, the two ends of the tube are open. Sometimes the cases are fixed, but more often portable. In the latter case the larva crawls about the bottom of the water or up the stems of plants, with its thickly-chitinized head and legs protruding from the larger orifice, while it maintains a secure hold of the silk lining of the tube by means of a pair of strong hooks at the posterior end of its soft defenceless abdomen. Their food appears for the most part to be of a vegetable nature. Some species, however, are alleged to be carnivorous, and a North American form of the genus Hydropsyche is said to spin around the mouth of its burrow a silken net for the capture of small animal organisms living in the water. Before passing into the pupal stage, the larva partially closes the orifice of the tube with silk or pieces of stone loosely spun together and pervious to water. Through this temporary protection the active pupa, which closely resembles the mature insect, subsequently bites a way by means of its strong mandibles, and rising to the surface of the water casts the pupal integument and becomes sexually adult.

The above sketch may be regarded as descriptive of the life-history of a great majority of species of caddis-flies. It is only necessary here to mention one anomalous form, Enoicyla pusilla, in which the mature female is wingless and the larva is terrestrial, living in moss or decayed leaves.

Caddis-flies are universally distributed. Geologically they are known to date back to the Oligocene period, and wings believed to be referable to them have been found in Liassic and Jurassic beds.

CADDO, a confederacy of North American Indian tribes which gave its name to the Caddoan stock, represented in the south by the Caddos, Wichita and Kichai, and in the north by the Pawnee and Arikara tribes. The Caddos, now reduced to some 500, settled in western Oklahoma, formerly ranged over the Red River (Louisiana) country, in what is now Arkansas, northern Texas and Oklahoma. The native name of the confederacy is Hasinai, corrupted by the French into Asinais and Cenis. The Caddoan tribes were mostly agricultural and sedentary, and to-day they are distinguished by their industry and intelligence.

CADE, JOHN (d. 1450), commonly called, English rebel and leader of the rising of 1450, was probably an Irishman by birth, but the details of his early life are very scanty. He seems to have resided for a time in Sussex, to have fled from the country after committing a murder, and to have served in the French wars. Returning to England, he settled in Kent under the name of Aylmer and married a lady of good position. When the men of Kent rose in rebellion in May 1450, they were led by a man who took the name of Mortimer, and who has generally been regarded as identical with Cade. Mr James Gairdner, however, considers it probable that Cade did not take command of the rebels until after the skirmish at Sevenoaks on the 18th of June. At all events, it was Cade who led the insurgents from Blackheath to Southwark, and under him they made their way into London on the 3rd of July. A part of the populace was doubtless favourable to the rebels, but the opposing party gained strength when Cade and his men began to plunder. Having secured the execution of James Fiennes, Baron Say and Sele, and of William Crowmer, sheriff of Kent, Cade and his followers retired to Southwark, and on the 5th of July, after a fierce struggle on London Bridge, the citizens prevented them from re-entering the city. Cade then met the chancellor, John
