America form a group distinct from those of the Old World, though closely allied thereto. 

 The Web-footed and the Star-nosed Moles are the most interesting of the American forms. 



Speaking of the prodigious speed with which these animals burrow their way through the 

 ground, Dr. Hart Merriam remarks that in a single night, after rain, they have been known 

 to make a gallery several yards in length, and that he had himself traced a fresh tunnel for 

 nearly a hundred yards. As he says, we can only appreciate the magnitude of this labour 

 by comparison, and " computation shows that, in order to perform equivalent work, a man would 

 have to excavate in a single night a tunnel thirty-seven miles long, and of sufficient size to 

 easily admit of the passage of liis body." 



The star-nosed mole is pjeeuliar in that its nose is surrounded by a ring of finger-like 

 jirocesses, forming a kind of rosette, which probably acts as a highly sensitive organ of touch ; 

 furthermore, it differs from other moles in tlie great length of its tail, which is nearly as long 

 as its body. Like the mole, this species makes its way through the ground with great speed. 



Beneficial as moles undoubtedly are in destroying worms and obnoxious insects, yet they 

 are regarded as a pest both by the farmer and gardener. That there is some justification for 

 this dislike must be admitted ; for the farmer suffers in that, in the search for food, crops are 

 damaged by cutting through the roots of plants — the gardener not only for the same reason, 

 but also because the ridges and hillocks which they make in their course disfigure the paths 

 and beds of a well-kejot garden.
