This consists of two pieces, as shown in Figs. 1 and 2 of [drawings No. 11], each piece so made as to cross and fit the other at the centre, hence called a Flower-Pot Cross, the whole being a test of exactness and good work, surpassing any preceding model.
Cut from Pine a piece 12 in. long, 11⁄4 in. wide, and 1⁄2 in. thick. Plane one side and one edge at right angles; then gauge for height and thickness, and plane the other side and edge as shown by the section represented in Fig. 3. Saw across the middle so as to make two pieces, and, from the end of each so cut, measure off and saw both to the equal length of 51⁄4 in. each, taking care that both ends of each are accurate right angles. Then place them on their sides and draw the centre line indicated by A B, continuing the line all round each piece. From the centre, mark off the places indicated by e f and g h. At c and d of each, with the compasses, describe the quarter circle shown at each top corner of the figures, striking the segments from the respective dots shown for the purpose near each top corner. Then, with the bottom edge for a base, draw a gauge line on each side of both pieces to the depth represented by i j, and with the tenon saw, make a slit at e and f to the depth of such gauge line. Then, with the knife or chisel, cut out the openings between e and f to the depth of the gauge line, taking care to finish the opening perfectly level and true. Then, at the bottom of one piece and the top of the other, as shown in Figs. 1 and 2, gauge, saw, and cut out the spaces from g to h in the same manner as for the spaces before mentioned. The openings from g to h, if well done, will fit accurately in all directions, and, when put together, will form a firm cross. Then, with the knife, round the corners of each piece, at c and d. Then smooth with file where required, and finish with sand-paper.

[3] No. 12 (Paper Knife) appears, for convenience of illustration, on [page 41], but it should be proceeded with before No. 13.
Cut from Beech a piece about 5 in. long, 1 in. wide, and 7⁄8 in. thick. Plane one side and one edge at right angles. Then saw across one end at right angles, and, measuring from that end, mark off the length at 41⁄4 in., and saw off that end at the mark, taking care to maintain right angles. Then gauge and plane the rough side and rough edge to a width of 7⁄8 in. and a thickness of 5⁄8 in. Then choose one edge for the top, and, along the centre of that edge, draw a line from c to c, as shown in Fig. 1 of [drawings No. 13], and continue the line to the extremities of both ends. Then, in manner described for No. 10, gauge, slit, and cut out with chisel the spaces shown in the same Fig. 1 of [drawings No. 13], from a to a and b to b. Then, with compasses, as indicated in the same Fig., describe on both sides of each top corner, the segment of a circle represented in each case from c to d. Then, for the first time, resort to Concave Chiselling, and with a broad chisel cut away the corners down to the segments previously described. This process requires great care and judgment. Fix one end of the work upwards in the bench screw, with the top side nearest to the operator, and, after taking off the corner to a considerable extent, with the bevelled side of the chisel towards the wood, shave small pieces away until the segment marks are reached, taking care to keep the whole curve at right angles to the sides throughout. Then, turn the work, and dress the corner at the other end in like manner. Then file judiciously where required, and finish with sand-paper.
