Make a one-bag batch of concrete in proportions, 1: 2½: 5. Have the mixture just wet enough to tamp well.
Place a 4-inch thickness of concrete to form a dish-shaped gutter 3 inches deep in the middle. Every five feet, make an expansion joint ⅛ of an inch wide by inserting a metal strip not less than 7 inches wide and 18 inches long, or by cutting a joint entirely through the concrete with a straight spade. Smooth the surface with a wooden float.

Repairs to Farm Buildings
Since wood always fails first at the ground, the use of concrete on the farm has developed from the ground up. After a farmer has had to replace several sills or blocks of wood, he begins to look about him for a new material which will not rot or will not have to be replaced. Concrete is his natural selection.
