GREAT NORTHERN RORQUAL. 141 



turned to an important economical purpose in con- 

 nexion with agriculture. It is well known that the 

 richest manure is formed from decayed animal matter, 

 and hence the great value of bone manure as an article 

 of commerce and of increased productiveness. Now, 

 no animal matter can exceed in richness that which 

 is supplied by the fatty matter so abundantly con- 

 tained throughout the whole frame, bones and all, 

 of the Cetacea. Hence the late Sir John Sinclair, 

 with that enthusiasm for his country's good which 

 ever characterized him, called the attention of the 

 agriculturist to this subject ; and, more lately, 

 Mr. William Bell has supplied an interesting notice 

 to the Quarterly Journal of Agriculture, vol. i., 

 concerning the use of dreg^ or coarse whale oil, in 

 converting peat moss, &c. into rich manure, and 

 finally into fine mould. His experiments on this 

 point were highly successful, and the result of his 

 promised additional observationjs will be esteemed 

 by the practical farmer.
