A very curious and interesting piece of work is shown in Illustration 329. It forms the back of a sconce owned by Francis H. Bigelow, Esq., and in his book “Historic Silver of the Colonies,” Mr. Bigelow describes the candle bracket, made in 1720 by Knight Leverett, which fits into the socket upon the frame. Benjamin Burt, the silversmith, in his will left to a niece “a sconce of quill work wrought by her aunt.” In 1755 a Mrs. Hiller advertised to teach “Wax work, Transparent and Filligree, Quill work and Feather work.” “Quill work” is made of paper of various colors, gilt upon one side, rolled tightly, like paper tapers. Some were pulled out into points, others made into leaf and petal-shaped pieces, and when finished they were coated with some waxy substance, and sprinkled with tiny bits of glass, all in gay colors, and when the candles were lighted the quill work glistened and sparkled. The quill work in this sconce is made into an elaborate design of a vase with flowers, and it is set into a very deep frame, and covered tightly with glass, which accounts for its perfect preservation. The top ornament to the frame is cut in the manner of looking glass frames of the period. [Illustration: Illus. 329.—Sconce of Quill Work, 1720.] The tripod screen in Illustration 330 is owned by Dwight M. Prouty, Esq. The little shelf for the candlestick drops on a hinge when not in use. The tripod feet have a light springing curve, and end in a flattened claw-and-ball. The original embroidery is still in the frame. [Illustration: Illus. 330.—Tripod Screen, 1770.] [Illustration: Illus. 331.—Tripod Screen, 1765.] Another tripod screen is shown in Illustration 331. It is owned by Cornelius Stevenson, Esq., of Philadelphia. The embroidery and the frame upon it were made in the nineteenth century but the stand is much earlier and is finely carved in the Chippendale style, with the French foot. Three serpents encircle the pole, from which they are completely detached. The wood is mahogany. [Illustration: Illus. 332.—Candle-stand and Screen, 1750-1775.] Screens were sometimes made of a piece of wood perforated, in order that the heat might not be entirely shut off. Illustration 332 shows one of these screens in the collection of the late Major Ben: Perley Poore. [Illustration: Illus. 333.—Chippendale Candle-stand, 1760-1770.] Both the screen and the candle-stand in the illustration are made of mahogany. The candlestick upon the stand is a curious one, of brass, with a socket for the candle set upon an adjustable arm, which also slides upon a slender rod, which is fastened into the heavily weighted standard. Both screen and candle-stand were made in the latter half of the eighteenth century. Candle-stands were designed by all the great cabinet-makers, and in those days of candlelight they were a useful piece of furniture.
