The concrete form for the sweep, shown in Fig. B, which is the underside of the top, must be made of fairly stiff sheet metal, securely attached to the wooden frame, as indicated. Mix enough concrete, using a wet concrete mixture, to build up the required thickness. This is placed on top of the clay mold previously made, and oiled and the metal template placed on the spindle. Sweep until the concrete surface is smooth. Pieces of fine mesh wire should be placed inside the concrete to stiffen it. Keep wet until thoroughly dry, which should be in two or three days. It will be noticed in the sectional view that the various parts are joined by means of a 4 inch rod or dowel. When putting the bird bath together, a small amount of "neat cement," which is cement with enough Water added to make a paste, is applied at all joints. Another method of sweeping the molds is to mix up just enough plaster of Paris to place under the sweep and sweep this very quickly with the template. The plaster sets quickly and the work must be done without loss of time. After the core is hard it should be sandpapered and shellac applied to the concrete surface. Oil the core and cover it with the concrete, packing it down firmly, and building up to the required thickness.

Place the template for sweeping out the inner or bowl part of the top, and sweep to the desired smoothness. This problem is not only interesting to construct, but is a valuable addition to any lawn or garden and at the same time attracts and benefits the birds. The design of a garage is generally influenced by the architectural treatment of the house and neighboring buildings. The logical location for the concrete garage is at the rear of the house, but this point must be settled to suit local conditions, the main idea being the convenience and accessibility from the street. Plate 38 gives a good type of concrete garage, but very few dimensions are given, as the size depends on the car to be housed and the amount of room available. It is well to plan ahead for the possibility of two automobiles, or space for a visiting car, or perhaps the letting of one-half of the garage. It is very necessary that the garage be as near fireproof as possible. Insurance companies allow lower rates on concrete constructed buildings. This type of garage is simple to construct, its upkeep is cheap, and it is permanent and needs no painting or repairing, is clean and easy to keep clean.

The method of constructing concrete forms and concrete floors is shown on previous plates. The floor should have a slight pitch to a drain in the center (see Plate 29), and the material required for the entire building is given on the drawing. This garage shows a shingled roof, but a concrete roof may be constructed instead, of a low arch type, the supporting concrete forms being constructed on the inside of the garage. The reinforcing of concrete walls for small buildings is a simple matter, but should receive careful attention. The reasons for such reinforcing are to prevent cracks, due to settlement, and to expansion and contraction from heat and cold. The reinforcing for a one-story building usually consists of a network of vertical and horizontal bars, placed in the center of the concrete walls, as is shown in Fig. A, Plate 39. There are various types of reinforcing rods, round, square, twisted or of special patent design. Rods should be wired together at all intersecting points and splices overlap a distance at least 64 times the diameter of the rod. All corners and openings require a special method of reinforcing. A simple and effective scheme for reinforcing is shown in Fig. B, Plate 39. Instead of being bent at the corners, the horizontal rods are terminated and securely wired to a vertical rod at this point.
