18 INTRODUCTION. 



tivators were considered as triflers, wasting their 

 energies upon that which could profit nothing ; and 

 the information which it affords was looked upon 

 as unworthy of the attention of persons fitted for

 compared with those beautiful organs of Divine 

 workmanship by which the swallow is conveyed
