232 WHALE-FISHERY. 



recover this oil without waste requires a little ad- 

 dress. A deal-board, in length a little exceeding 

 the breadtli of the cooler, is introduced at one end, 

 a little diagonally, and placed edgewise in its con- 

 tents. The ends of the board being covered with 

 flannel, when pressed forcibly against the two op- 

 posite sides of the cooler, prevent the oil from cir- 

 culating past. The board is then advanced slowly 

 forward, towards the part of the back, where the 

 stop-cock is placed; and in its progress, (the ends 

 being kept close to the side of the cooler, and the 

 upper edge a little above the surface of the oil,) all 

 the oil is now collected by the board, while the wa- 

 ter has a free circulation beneath it. When the oil 

 accumulates to the depth of the board, its further 

 motion is suspended, until the oil, thus collected, 

 is drawn off. Another similar board is afterwards 

 introduced at the farthest extremity of the cooler, 

 and passed forward in the same maijuer, whereby 

 the little oil which escapes the first is collected. 

 Now the remnant, which still refuses to run off by 

 the orifice of the stop-cock, being collected in a cor- 

 ner, is taken up by skimmers; and the footing or 

 sediment which appears at the last, is disposed of 

 in the same way as the footing from the copper, un- 

 til the oil it contains rises to the surface and can be 

 removed. 



In most of the out-ports, the oil is generally de- 

 posited in casks, in which it remains until it is dis- 

 posed of by the importers. In London, however,
