One-inch grooved and tongued boards 6 in. wide is a suitable material of which to make the portable dog-kennel illustrated by Fig. 1. The boards of the sides should he nailed to a l1/2 -in. by 2-in. ledge at the top and a 3-in. by l1/2 -in. ledge at the bottom (see K and L, Fig. 2). The boards of the front and back should be nailed to similar ledges, as shown at E and F (Fig. 1). The boards forming each side of the roof should be nailed to the three bearers M, N, and 0 (Fig. 2). Fig. 3 shows the construction of the floor. It will be seen that the kennel will be composed of seven main pieces. A fillet about 1 1/2 in. by 1 1/2 in. should be nailed to each end of the sides, as shown in the longi-tudinal section (Fig. 2), and also by the enlarged section (Fig. 4): this is taken through A (Fig. 1). B (Fig. 4) shows a portion of the hoarding of the side with the angle fillet D nailed to it. The front and back can be fixed to the sides by eight 2 1/4-in. by 3/8-in. bolts and nuts, as shown at Figs. 1 and 2, and indicated by the section, Fig. 1. Each half of the roof can be fixed to the ends by eight bolts and nuts in a similar manner. The floor will rest on the ledges G and II (Fig. 2) round the bottom of the boarding. The roof should be covered with felt.
