ABSTRACT OF THE DISCLOSURE A construction block adapted to interact with other like blocks comprises a body substantially in the shape of a rectangu- lar parallelepiped having a front face, a rear face, a top face, a bottom face and a pair of side faces. The bottom face has a plur- ality of substantially identical grooves formed therein, parallel with the front face, and extending across the bottom face from one side face to the other. These grooves are of generally constant cross-section and are spaced apart evenly between the front face and the rear face of the block. The top face of the block is provided with at least two ridges thereacross, parallel with the grooves, and each receivable within a groove of a like construc- tion block. There are fewer ridges than grooves, and the outer- most of the ridges are spaced from the front and rear faces of the block at least the distance between said faces and the second closest groove.
