This problem is designed chiefly to familiarize the pupil with the making of a simple form and the proportioning, mixing and casting of concrete. The base-board for the form is 4inch x 12 inch, made from 18 inch material. The ends are 8 inch x 4 x 8 inch. Two of these are required. The two sides are Y8 inch x 22 inch x 12 inch, with two blocks Y8 inch x      4 inch x 2/2 inch attached Ys inch in from the ends with screws, as shown. Mix the necessary amount of cement and sand in proportions of 1 part cement to 3 parts sand as described in chapter under "Mixing." Place a wooden clamp in place shown in sketch and leave 24 hours. Plate 6 shows the drawing of the form for a concrete anchor weighing about 25 lbs. This problem, while a very, little more difficult than that of Plate 5, is simple enough in concrete construction for a fifth or sixth grade boy. The two larger sides A are cut 9 inch x 103/2 inch and then tapered on one end to 84 inch, as shown. Attached to the two sloping edges are two pieces 8 inch x 18 inch X 93 inches. Sides B are first cut 7 inch x 9 inch and tapered to 5 inch The base C is inch x 83/4 inch x 10Y2 inch The top and bottom edges of A and B are leveled as indicated in sketch. Two scrap sticks are partly nailed on to the edges of sides A, as shown, and the ringbolt suspended while the form is being poured.

The sides A are also lightly nailed to the base so as to be easily removed when the form is hard. Leave in the form 24 hours. An interesting feature of this problem is the figuring -out beforehand of the weight of the anchor. This is done as follows: The shape of the anchor is in the form of a truncated pyramid. It is necessary to first find the cubical contents, which is obtained by taking a section through the average height, which is 43/2 inch perpendicularly up from the base (the total height being 9 inch). This gives us the average section, square in shape, and 6 inch on a side. The area of this section is then 6 inch x 6 inch or 36 sq. inch. Multiplying this by the height, 9 inch, we have 36 x 9 inch, equaling 324 cu. inch in volume. There being 1728 cu. inch in a cubic foot, we have 324 cu. inch divided by 1728, which equals 3/16 cu. ft. A cubic foot of concrete weighs from 130 to 140 lbs. varying according to the kind of crushed stone used, granite being the heaviest. Taking 135 lbs. as the average weight we find that 135 divided by 3/16 equals 25 5/16 lbs., the weight of the anchor. The writer has found that the boys are extremely interested, after figuring out beforehand the weight of the anchor, to verify their calculations by actually weighing the finished problem. A very serviceable horse weight can be cast, on the same principle, by reducing the dimensions of the form. Plate 8 shows drawings and sketch of a concrete roller weighing about 265 lbs. and is suitable for rolling lawns, etc., requiring two men to operate. The form for this roller is made from a piece of sheet iron cut 24 inch by 563/2 inch. The edges must he cut square and even.

Make two sets of wooden clamps, like the circular form shown in the drawing. Bend the piece of sheet iron in a circle and nail, if necessary, to the two wooden clamps. Wire the iron form or jacket with No. 16 wire to hold the form from opening at the joint when the concrete is placed. Grease or oil the inside of the form thoroughly so that it will not stick to the concrete. To make an opening through the center of the roller for the axle or shaft, place a 4 inch or 3/8 inch iron pipe in the center of the form. The axle can be cast in the roller itself if desired instead of casting a 3/4 inch or 3/8 inch pipe in the roller in which to place the axle. The concrete should be made of 1 part cement, 2 parts of sand and 4 parts of stones or gravel. It will take a little less than 1 hag of cement for a roller of the above dimensions. The handle may be made of 1 inch iron bent and welded together as shown in the figure. A discarded lawnmower handle could be used and the iron work bolted to the same.
