Cores are employed mainly for what may be termed the displacement of metal in moulds. There is no clear line of distinction between cores and moulds, as founding is now conducted; cores may be of green sand, and made to surround the exterior of a piece, as well as to make perforations or to form recesses within it. The term 'core,' in its technical sense, means dried moulds, as distinguished from green sand. Wheels or other castings are said to be cast in cores when the moulds are made in pieces and dried. Supporting and venting cores, and their expansion, are conditions to which especial attention [95] is called. When a core is surrounded with hot metal, it gives off, because of moisture and the burning of the 'wash,' a large amount of gas which must have free means of escape. In the arrangement of cores, therefore, attention must be had to some means of venting, which is generally attained by allowing them to project through the sides of the mould and communicate with the air outside.The spiteful little ripple of laughter was hushed as Leona Lalage returned.

ONE:The little room was at the top facing the blank windows of the Corner House. Hetty had no difficulty in finding the box, and a very brief search showed the address she was looking for. The box she emptied in the grate and set fire to the contents with a match she had brought for the purpose.

TWO:The woman's eyes flashed again. All this was taking time. Balmayne would wonder what had happened to her. From the bottom of her heart she was praying that he might come up and see. Not that there was much real hope of that--physical courage was not one of Louis Balmayne's strong points.
