relative to one another also referred to hereinafter as a stack as shown in fig3 the central vertical cavities 12 of each masonry unit should be generally aligned with the central vertical cavities 12 of the other units so long as the central vertical cavities 12 of each unit are generally the same shape and are generally aligned any bonding material poured into a central vertical cavity 12 of the uppermost unit 100 will also pour through the corresponding central vertical cavity 12 of each unit below in the stack due to the force of gravity this allows a craftsman to quickly create a wall by stacking the masonry units one on top of one another and then pouring bonding material through each vertical cavity as the wall is completed and judged to be in the proper shape and alignment in the preferred embodiment the central vertical cavities 12 are surrounded by a sloped edge 12 a as shown in fig1 and 2 preferably at or near a forty five degree angle from the horizontal plane to act as a funnel creating a larger void between the upper and lower masonry units thus assisting the bonding material in its movement into the lower portions of the stack as shown in fig2 the masonry unit 100 comprises a plurality of support members 21 projecting vertically out from the lower surface 20 of the masonry unit preferably eight support members 21 are employed however a greater or fewer number of support members 21 can be employed as shown in fig1 the masonry.
