Strictest attention shouldbe paid to the leyelling of the lowest cotirse of footings of a wall,for any irregularity will necessitate the inequality being made upwith-mortar in the courses above, thus inducing a liability forthe wall to settle unequally, and so perpetuate the save the trouble of keeping the plumb-rule and level con-stantly in his hands and yet ensure correct work, the bricklayer,on clearing the footings of a wall, builds up six or eight coursesof bricks at the external angles (see fig. i), which he carefullyplumbs and levels across. These form a gauge for the iiitervening.

If, however, thelength between the quoins be great, the line will of course sag,and itmust, therefore, be carefully supported at intervals to theproper level. Care must be taken to keep the perpends,or vertical joints, one immediately over the other. Having besencarried up three or four courses to at level with the guidance ofthe line which is raised course by course, the work should beproved with the levd and plumb-xule, particularly with the letterat the quoins and reveals, as well as over the face.
