N, B. It is but justice to say, that this attempt at a scienti- 

 fic arrangement of soils, was commenced by Dr. T. Romeyn 

 Beck and myself, in the summer of 1820, while taking an 

 agricultural survey of Albany county. And it was considera- 

 bly extended by Prof, h, C. Beck, and myself, in taking the 

 Rensselaer county survey, the year after. Being wholly ori- 

 ginal in the arrangement, its errors and defects are unsupport- 

 ed by the authority of names ; consequently, it should not, and 

 will not, be received without much caution and frequent revi- 

 sion. The same remarks will apply to a large proportion of 

 this text-book.
