Title: Brick having complementary ends

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to bricks and more particularly to a brick having two complementary ends so that mortar filled the gaps between one end of a brick and the other complementary end of an adjacent brick may bind them together for a prolonged period of time. 
     2. Description of Related Art 
     A circular brick wall built by conventional rectangular bricks A is shown in  FIG. 1 . One drawback of the bricks A is that mortar filled the gaps between the bricks A may not bind them together for a prolonged period of time. This is because two ends of the brick A are flat and the binding force exerted on the bound ends of the bricks A is not sufficient. 
     Thus, the need for improvement still exists. 
     SUMMARY OF THE INVENTION 
     It is therefore one object of the invention to provide a brick comprising a concave first end, a convex second end, a first side, a second side, a top, and a bottom wherein the first end and the second end are complementary. 
     The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
