76 DISEASES OF CROPS. 



which infest root crops. Some belong to the animal, 

 others to the vegetable kingdom. Every ctiltivated plant 

 has its own foes ; but whether we look upon them as 

 enemies or not, they have all come into the world for the 

 same object as the rest of animated nature — namely, to 

 live, reproduce, and die — so the world goes on ! They 

 are, therefore, part and parcel of the organic world and 

 not isolated from it. In the words of Carlyle:' "De- 

 tached, separated ! I say there is no such separation : 

 nothing hitherto was ever stranded, cast aside ; but all, 

 were it only a withered leaf, works together with all ; is 

 borne forward on the bottomless, shoreless flood of Action, 

 and lives through perpetual metamorphoses. . . . 

 Rightly viewed, no meanest object is insignificant ; all 

 objects are as windows, through which the philosophic 

 eye looks into Infinitude itself."
