The horri-zontal joints are made with alternate projec-tions and depressions, and the several coursesare connected vertically by dowel piles, whichalso serve as guides in sinking the application of this principle is capableof modification to suit almost every variety ofconstruction, and it will be found especiallyapplicable in structures requiring heavyfoundations, particularly where the ground ison
