A building wall comprising the plurality of stacked logs with flat top and bottom surfaces into each of which is cut a deep slot. A metal bar is received in the aligned slots of vertically adjacent logs and pointed projections penetrate into the wood of the logs to prevent separation. In one embodiment, the projections are spaced clusters of downwardly extending nails which prevent separation of logs placed end to end and upwardly extending nails which prevent shear movement of adjacent logs. In another embodiment, the bar has sharp projections which are punched from the surface thereof to be received in the aligned slots of adjacent logs and penetrate a side wall of said slot.
