with a moulding plane in these shops, but in London or large towns the machine would be used for straight and shaped pieces alike. This moulding would be made in one straight piece and framed up later together with the shaped pieces.
After the astragals have been worked, the uniting pieces at the top, bottom, and sides would be cut out read)' for the carver, but before, the grooves for the strengthening fillets which form the double rebates would be scratched in these and the astragals. Fig. E shows the astragals grooved with the fillets inserted. The astragals are then polished, and mitred together on the set-out board, and cut in, to intersect with the ovolo on the framing of the doors, and they are then neatly glued together and allowed to set. The backboard is then removed, and although the lattice is too weak to stand any strain, the gluing of the mitres will hold it sufficiently to permit of the fillets being glued in the grooves behind. It is presumed that the carved ties at the top, bottom, and sides of the oval have been made and fitted with the lattice. The grooves behind in these would only mm through the centres, from the oval to the framing, the fronds of the honeysuckle at the top, for instance, being allowed to rest on the glass, secured only by cement or fish glue. The door is now turned over on its face, and the fillets, of width just sufficient so as to come flush with the inside face of the door when they are in position, are put in. To get the maximum of strength, these fillets are not mitred, but allowed to run through in one length the one way across, the transverse being butted or lightly cut in, in a V groove, into the other, as shown in Fig. E. These fillets, being usually only one-eighth of an inch in thickness, are bent into shape, instead of being cut, thereby avoiding short-grain wood. The glass is then cut for the panels formed by the rebates on either side of the fillets, and is either puttied or beaded in ; the former is more usual, and is stronger, although the glasses are more difficult to replace in the event of breakage. The fitting of the lock, bolts, and the hinges, and the polishing of the flat faces of the framing, complete the door, which is then ready for hanging.
It will be seen from the above that the process of constructing these lattice doors is very different to that described by Sheraton in the Drawing Book. What is also more material for our present purpose is, that the method here described is the one which was generally followed in the eighteenth-century work. However the trifling details may have been varied in different shops, the finished result must have been the same, as astragals built up of several veneer thicknesses are never found in cabinet and bookcase doors of the period. One is forced to the conclusion that the technical training in his craft which Sheraton received in bis native town did not include any experience of the construction of lattice doors, although it is characteristic of the man that the lack of this knowledge did not prevent him from instructing his fellow-workmen in the same way as if he possessed it.
