" The sulpliuric acid, lime, magnesia, potassa, soda, chlorine 

 and phosphoric^acid, of this soil, are in such small proportion, 

 that the greater portion of them will be considerdbly exliausted in 

 the course of a few years, by cropping without tlie addition of 

 manures. The percentage of organic matter is also too small to 

 indicate a soil of great productiveness and retentive power. 



" The best and most aviiilable manures indicated by the above 

 analysis, for the region where the soil lies, are barn-yard manures 

 or peat mixed Vvith hard wood ashes leached, or better unleached. 

 The phosphate of lime, plaster, caustic lime, and guano, will all 

 be found \5aluable ai)plications." 



The specimen marked No. 27, is from the ^' intervale" on the 

 bank of the Eoquet, upon the farm of C. A. Wakefield, in Eliza- 

 bethtown, and is a type of the alluvial tracts which occur in the 

 county. Prof. Salisbury says, " No.^ 27 is a very excellent soil. 

 Under the microscope it is seen to be composed of quartz, mica, 

 felspar- and hornblende, with an occasional small particle of 

 calcspar, and a few other minerals. It is quite rich in organic
