To obviate this tendency tosettle and thus cause the bulging of the face or failure of the wall,the mortar used should be composed, of Portland cement and sandwith a large proportion of the fprmer, and worked as stiff, as itconveniently can lie: In building such work the stones should be inheight equal to an exact number of brick courses.
