KINDS OF EARTH. 



Vineyard Soil of Rotheberg, near Gaissheim, in the Rhein- 

 Gau — a great preponderance of siliceous earth, with particles 

 of clay-slate, and some lime, with 3.3 per cent, of humus and 

 volatile matter. 



Vineyard Soil of Neudorf, in the Rhein-Gau, of similar com- 

 position, containing 5.2 per cent, of humus and volatile 

 matter. 



Sterile Sandy Soil from the Vogelsang, near Gottingen — 88 

 per cent, of sand and tiinty matter, with some lime, clay, and 



4.2 humus and volatile matter. 



Vineyard Soil from Riidesheira, in the Rhein-Gau— similar to 

 the two first vineyard soils, with somewhat more lime, and 



8.3 per cent, of humus and volatile matter. 



Vineyard Soil of Liebfrauenkirche, near Worms — 66 .5 per

 cent, of lime, some clay, and 8 per cent, of humus and volatile 

 matter. 



Very fertile Arable Soil of East Friesland — 64.8 per cent, 

 of (in a great measure) fine silica, 9 . 7 of lime, 5 . 7 of alumina, 

 with 11 . 2 of humus and volatile matter. 



Vineyard Soil of Johannisberg, in the Rhein-Gau — 54 per 

 cent, of sand (consisting of particles of clay, slate, and quartz), 

 9 per cent, of lime, 37 of clay, and 5.5 of humus and volatile 

 matter. 



Sandy Soil from the Black Forest — 77 per cent, of quartz-sand, 

 with 20.1 of clay, some lime, and 1.3 of humus and volatile 

 matter : beautiful pine-forests.

 consisting of clay, with 0 . 4 per cent, of lime, and 8 . 8 of humus 

 and volatile matter. 



Fertile Arable Soil from the corn-fields in the valley of the 

 Neckar, near Tiibingen, a calcareous clay land — 62 per cent, 

 of clay, 28.8 of siliceous sand, 3.4 of lime, and 5.7 of humue- 

 and volatile matter. 



Fertile Arable Soil of Gottingen — 83.3 per cent, of siliceous 

 sand, with (in a great measure) fine deposited silica, 5.1 of
