=The Stability of the "Grandfather" Clock.=--The long-case clock had become a piece of furniture. It was of marquetry decoration, in keeping with contemporary tables and cabinets, or it was lacquered in rich colours in "Chinese taste" to keep touch with the Oriental parlours. But concurrent with the age of marquetry and lacquer was the great walnut period. The delightful veneer of burr-walnut in Queen Anne days in cabinets and chests of drawers and other important pieces of furniture did not neglect the clock-case. The gnarled figure of the walnut was essentially a proper decoration to apply to the clock-case. The long-case clock had not only become acclimatized, but it had become thoroughly English. The simplicity of its construction, and its proud record as a perfect timekeeper, gave it the supremacy over all other clocks. English clockmakers, with the fine sense of practical utility which governed their employment of mechanism, had reached a point when further inventions became more of scientific use than popular. The "grandfather" clock has no equal within its limits. It runs for eight days. Its construction is so simple that when needing repair it need not be sent to a specialist. It has no delicate parts to confound the provincial maker. Hence it has lasted two centuries and more as a standard English clock. There is, too, a certain lovableness about the "grandfather" clock. The popular term suggests this. It is the heritage of the poor. The "grandfather" clock of the yeomanry has passed down through many generations. Indeed, the love of it as an article of furniture has, in many instances, endowed it with a value far greater than it possesses. =The Burr-walnut Period.=--Veneer had become an established technique. Woods with fine figure served as panels laid on wood of lesser rarity or decorative importance. Oak was a good foundation for walnut veneer. Earlier, as we have seen, walnut was laid as a ground on oak and the marquetry design laid on the walnut. But in the burr-walnut period carefully selected walnut sheets were employed to decorate surfaces of bureaus and clock-cases. The age of walnut is synonymous with the days of Hogarth. Burr-walnut clock-cases are not so frequently found as could be wished. The burr-walnut panels are marked in a series of knot-like rings, obtained from the gnarled roots of the walnut-tree. The peculiar pleasing effect of this and other mottled walnut is heightened by the mellow effect time always gives to these walnut examples, which cannot be produced with any appreciable success by modern imitators.
