 fed upon whale or seal blubber, if the digestion is 

 good, have much fatty deposit upon the body, and 

 the perspu-ed fluid is oil. It is a fact well known to 

 every intelligent farmer, that infield or croft land, 

 that is land, which, having been earliest cultivated, 

 was, of course, the best soil at first, and which has 

 also been long highly manm-ed at the cost of the
