The invention is hereby claimed as follows: 1. In a building block system for constructing walls of a building including a plurality of stacked courses of mortarless interlocking building blocks, the improvement in the building block which comprises: an injection molded plastic body having a front

The invention is hereby claimed as follows: 1. In a building block system for constructing walls of a building including a plurality of stacked courses of mortarless interlocking building blocks, the improvement in the building block which comprises: an injection molded plastic body having a front face, a rear face, opposed top and bottom faces and opposed end faces, one of said opposed end faces having at least one vertically extending tapered socket and the other of said end faces having at least one vertically extending tapered extrusion for mating with said socket to interconnect adjacent blocks in end-to-end relation, said top and bottom faces having a plurality of interengageable mating posts and sockets to lock stacked blocks against slidable movement therebetween, said opposed front and rear faces being substantially identical and including a at least one vertically extending socket for matingly receiving an extrusion of an end face of a block, and a plurality of vertically extending holes in the block body arranged symmetrically such that the weight of the block is greatly reduced. 2. The block of claim 1, wherein one of the end faces include a plurality of sockets and the other a plurality of extrusions. 3. The block of claim 1, wherein one end face includes two spaced apart extrusions, and the other end face includes two spaced apart sockets. 4. The block of claim 1, wherein each of the front and rear faces includes a plurality of sockets. 5. The block of claim 1, which further includes means such that vertically cutting the block in half produces a first block half in size with at least one extrusion on one end face and at least one socket on the other end face, and a second block half in size with at least one socket on each of its end faces. 6. The block of claim 1, which further includes means such that vertically cutting the block at one quarter of its length produces a first one-quarter size block having at least one extrusion on one end face and at least one socket on the other end face, and a second three-quarter size block having at least one socket on each of its end faces. 7. The block of claim 1, which further includes means such that vertically cutting the block at three-quarter of its length produces a first three-quarter size block having at least one extrusion on one end face and at least one socket on the other end face, and a second one-quarter size block having at least one socket on each of its end faces. 8. The block of claim 1, which further includes means such that vertically cutting the block at three-quarter, half, or one-quarter sections respectively produces a first three-quarter, half or one-quarter size block having at least one extrusion on one end face and at least one socket on the other end face, and second one-quarter, half and three-quarter size block having sockets on each of their end faces for use in adjusting the length of a course. 9. The block of claim 1, which further comprises spacing said posts such that the block may be vertically cut into three-quarter, half or one-quarter sections, and means in the block whereby the opposed end faces of one of the sections include at least one vertically extending extrusion and at least one vertically extending socket and the other of said sections includes at least one socket at each of its end faces. 10. The block of claim 1, wherein the posts and sockets of the top and bottom faces are square in cross section. 11. The block of claim 1, wherein the posts and sockets of the top and bottom faces are round in cross section. 12. The block of claim 1, wherein said at least one extrusion and said at least one socket on the end faces and front and rear faces are complementally tapered. 13. A mortarless interlocking building block for constructing walls and/or partitions of a building comprising: an injection molded plastic body having a front face, a rear face, opposed top and bottom faces and opposed end faces, one of said opposed end faces having at least one vertically extending tapered socket and the other of said end faces having at least one vertically extending tapered extrusion for mating with said socket to interconnect adjacent blocks in end-to-end relation, said top and bottom faces having a plurality of interengageable mating posts and sockets to lock stacked blocks against slidable movement therebetween, said opposed front and rear faces being substantially identical and including a at least one vertically extending socket for matingly receiving an extrusion of an end face of a block, and a plurality of vertically extending holes in the block body arranged symmetrically such that the weight of the block is greatly reduced. 14. The block of claim 13, wherein one of the end faces include a plurality of sockets and the other of the end faces includes a plurality of extrusions. 15. The block of claim 13, which further includes means such that vertically cutting the block into three-quarter, half or one-quarter sections respectively produces a first three-quarter, half or one-quarter size block having at least one extrusion on one end face and at least one socket on the other end face and a second one-quarter, half or three-quarter size block having at least one socket on each of its end faces for use in adjusting the length of one course. 16. The block of claim 13, wherein the mating posts and sockets are polygonal in cross section. 17. The block of claim 13, wherein the mating posts and sockets are square in cross section. 18. The block of claim 13, wherein the mating posts and sockets are round in cross section. 19. The block of claim 13, wherein said vertically extending socket is a female dovetail socket and said mating vertically extending extrusion is a male dovetail protrusion. 20. The block of claim 19, wherein a pair of female dovetail sockets are provided on one end face of the block and a pair of male dovetail protrusions are provided on the other end face of the block. 21. The block of claim 20, wherein said block includes longitudinally spaced apart channels, and each channel cross-sectionally shaped to form a pair of facing female dovetail sockets for mating with a male dovetail protrusion/connector. 22. In a building block system for constructing walls of a building including a plurality of stacked courses of mortarless interlocking building blocks, the improvement in the building block which comprises: an injection molded plastic body having a front face, a rear face, opposed top and bottom faces and opposed end faces, one of said opposed end faces including a pair of spaced apart vertically extending tapered sockets on one of said end faces and the other of said opposed end faces including a pair of spaced apart vertically extending tapered connectors for mating with said sockets to connect adjacent blocks together, said top face having a pair of rows of longitudinally spaced apart posts and said bottom face having a pair of rows of longitudinally spaced apart sockets complementally formed for engagement by said posts, said opposed front and rear faces being substantially identical and including a plurality of vertically extending sockets of the same configuration as said sockets on an end face to matingly receive connectors of said opposed end face of a block, a plurality of symmetrically arranged vertically extending openings to define a thin walled block of light weight including openings that define opposed tapered sockets such that when cutting a block along a plane into three-quarter, half and one-quarter sizes will define along the cutting plane vertically extending sockets matable with vertically extending connectors. 23. The block of claim 22, wherein the end face sockets are dovetail shaped, and the end face connectors are dovetail shaped.
