CRESWICK, THOMAS (1811-1869), English landscape-painter, was born at Sheffield, and educated at Hazelwood, near Birmingham. At Birmingham he first began to paint. His earliest appearance as an exhibitor was in 1827, at the Society of British Artists in London; in the ensuing year he sent to the Royal Academy the two pictures named “Llyn Gwynant, Morning,” and “Carnarvon Castle.” About the same time he settled in London; and in 1836 he took a house in Bayswater. He soon attracted some attention as a landscape-painter, and had a career of uniform and encouraging, though not signal success. In 1842 he was elected an associate, and in 1850 a full member of the Royal Academy, which, for several years before his death, numbered hardly any other full members representing this branch of art. In his early practice he set an example, then too much needed, of diligent study of nature out of doors, painting on the spot all the substantial part of several of his pictures. English and Welsh streams may be said to have formed his favourite subjects, and generally British rural scenery, mostly under its cheerful, calm and pleasurable aspects, in open daylight. This he rendered with elegant and equable skill, colour rather grey in tint, especially in his later years, and more than average technical accomplishment; his works have little to excite, but would, in most conditions of public taste, retain their power to attract. Creswick was industrious and extremely prolific; he produced, besides a steady outpouring of paintings, numerous illustrations for books. He was personally genial—a dark, bulky man, somewhat heavy and graceless in aspect in his later years. He died at his house in Bayswater, Linden Grove, on the 28th of December 1869, after a few years of declining health. Among his principal works may be named “England” (1847); “Home by the Sands, and a Squally Day” (1848); “Passing Showers” (1849); “The Wind on Shore, a First Glimpse of the Sea, and Old Trees” (1850); “A Mountain Lake, Moonrise” (1852); “Changeable Weather” (1865); also the “London Road, a Hundred Years ago”; “The Weald of Kent”; the “Valley Mill” (a Cornish subject); a “Shady Glen”; the “Windings of a River”; the “Shade of the Beech Trees”; the “Course of the Greta”; the “Wharfe”; “Glendalough,” and other Irish subjects, 1836 to 1840; the “Forest Farm.” Frith for figures, and Ansdell for animals, occasionally worked in collaboration with Creswick.
In 1873 T. O. Barlow, the engraver, published a catalogue of Creswick’s works.
CRESWICK, a borough of Talbot county, Victoria, Australia. 85½ m. by rail N.W. of Melbourne. Pop. (1901) 3060. It is the centre of a mining, pastoral and agricultural district. Gold is found both in alluvial and quartz formations, the quartz being especially rich. The surrounding country is fertile and well-timbered, and there is a government plantation and nursery in connexion with the forests department.
CRETACEOUS SYSTEM, in geology, the group of stratified rocks which normally occupy a position above the Jurassic system and below the oldest Tertiary deposits; therefore it is in this system that the closing records of the great Mesozoic era are to be found. The name furnishes an excellent illustration of the inconvenience of employing a local lithological feature in the descriptive title of a wide-ranging rock-system. The white chalk (Lat. creta), which gives its name to the system, was first studied in the Anglo-Parisian basin, where it takes a prominent place; but even in this limited area there is a considerable thickness and variety of rocks which are not chalky, and the Cretaceous system as a whole contains a remarkable diversity of types of sediment.
Classification.—The earlier subdivisions of the Cretaceous rocks were founded upon the uncertain ground of similarity in lithological characters, assisted by observed stratigraphical sequence. This method yielded poor results even in a circumscribed area like Great Britain, and it breaks down utterly when applied to the correlation of rocks of similar age in Europe and elsewhere. Study of the fossils, however, has elicited the fact that certain forms characterize certain “zones,” which are preceded and succeeded by other zones each bearing a peculiar species or distinctive assemblage of species. By these means the Cretaceous rocks of the world have now been correlated zone with zone, with a degree of exactitude proportional to the palaeontological information gained in the several areas of occurrence.
The Cretaceous system falls naturally into two divisions, an upper and a lower, in all but a few limited regions. In the table on page 288 the names of the principal stages are enumerated; these are capable of world-wide application. The sub-stages are of more local value, and too much importance must not be attached to them for the correlation of distant deposits. The general table is designed to show the relative position in the system of some of the more important and better-known formations; but it must be remembered that the Cretaceous rocks of Europe can now be classified in considerable detail by their fossils, the most accurate group for this purpose being the cephalopods. The smaller table was compiled by T. C. Chamberlin and R. D. Salisbury to show the main subdivisions of the North American Cretaceous rocks. The correlation of the minor subdivisions of Europe and America are only approximate.
