=Thomas Chippendale--The Mahogany Period.=--There is no doubt that the name of Thomas Chippendale will always be representative of the mahogany period of English furniture. But there were other makers contemporary with him who did splendid work. The Chippendales, Thomas the father and Thomas the son, picture-frame carver and cabinet-maker at Worcester, migrated together to London in 1729. The son, Thomas, published his _Director_ in 1754. He was the leading cabinet-maker and designer of his day, and his day lasted till about 1780, when his son, Thomas Chippendale the third entered into partnership with Haig, and the firm became Chippendale and Haig, who also in turn produced magnificent work. Close upon the heels of the Chippendales was the firm of Hepplewhite. The brothers Adam, architectural designers and creators of furniture suitable for its new classic environment, began to make their impress upon interior decoration and on furniture, as they had upon Princes Street, Edinburgh, the Quays at Dublin, and the Adelphi in London, with their patent stucco mouldings and festoons.

Daniell & Sons._)] Accordingly, the student must bear in mind these great movements taking place during the second half of our Georgian period, viz. from about 1740 to the year 1791, at which date appeared the first edition of Sheraton's _Cabinet Maker and Upholsterers Drawing Book_, to herald another style, blended with the Adam, but departing from it at important points. In examining clock-cases of this prolific and restless period, it should be of exceptional interest to the connoisseur to show how unnamed cabinet-makers in London and in the provinces attempted to employ, with varying degrees of skill, the designs promulgated broadcast by these great teachers of design and construction in cabinet work. =Innovations of Form.=--As exemplifying the variations of the mahogany period clock-case, we illustrate several types showing reflections of the great impulses that were in the air. The clock, illustrated (p. 239), has a case of Spanish mahogany with fine figure. The hood is enriched with fretwork, and with elegantly moulded door, and the superstructure as a pediment exhibits the Chinese style. The terminals are mahogany. The dial shows phases of the moon, and the movement is by a provincial maker, E. Cockey, Warminster.
