The fact, also, that different engines or lathes can produce at a prodigious rate certain separate parts of many pieces of furniture, has made skilled mechanics less universal "all round" men than they were. If this combination of qualities is to be met with in provincial towns or villages, there, without doubt, the standard of excellence is a lower one.
_Materials and Execution._--The woods used for making furniture besides pines and deals, are birch and beech (used for stuffed chair-frames, couches, &c.) walnut, letter wood, Spanish and Honduras mahogany, sycamore, lime, pear, cherry of several kinds, and maple; ash, English, American, and Hungarian; oak, English, foreign, and pollard, with pieces cut from wens and sweet cedar. Turners use also plane, laburnum, yew, holly, and box. More precious woods are also used in furniture: rose-wood, satin-wood, ebony, and sandal-wood. Other rare woods are used in inlaying and marquetry.
Some of these materials, mahogany and walnut, which are much in use, are imported in vast logs, the former sometimes three feet square; when of very fine grain suited to veneers, worth 1000_l._ or more, per log.
The woods are stacked in yards, or, in London, where the space cannot otherwise be had, on platforms resting on the walls of the workshops, and fully exposed to the weather. Woods are dried after a year, or two years, according to the size of the log and nature of the wood. Oak is sometimes kept for eight or more years. When sawn into the scantlings required, it is further dried by placing the logs and planks in rooms heated by the waste steam from the engine. An American patented method of drying is to place a coil of pipes, through which exceedingly cold water is passed in the drying room, which condenses and carries off the vapours from the wood exposed to this heat. Some firms have tried this method, but, I believe, without much success.
Logs are cut up by the engine with three or more perpendicular saws at once, the teeth being set to the right and left alternately, to open a passage for the blades. More valuable woods, e.g. mahogany, are cut into thin plank by an horizontal saw. In this case the teeth are not bent, but a labourer opens the passage for the blade by lifting the plank with a wedge. As little waste of the material as possible is thus secured.
