The usual failures inthese styles of boxes are pulling of the nails fromends and cleats, shearing out the nails to the ends ofthe sides, top, and bottom, and splitting of the endboards along the inner edges of the horizontal cleats,which allows a cleat with part of the end board topull away with the top and bottom. The resistanceto failure by splitting of the end is due to the strengthof the end board in tension across the grain, supple-mented by the action of the vertical cleats. In nail-ing the vertical cleats to the ends in styles 2 and 2^,it is possible to get more nails near the top and bot-tom
