A good many farmers are coming around to the idea that it pays to invest a little bit more in a building at the start so as to get away from the upkeep expense later on. They are turning to clay tile more and more. The building material dealers and the rural builders are lining up with the farmers on this proposition. The lumber dealers are carrying in stock a line of all the commonly used sizes, and the builders are finding out that it is no trick at all to lay up a tile wall and make a good job of it.
