13.08 per cent of its weight, consisting mainly of water and

"One thousand parts of the soil treated with 2,000 parts 

 water produced a solution which left, at 212° to 220° F., a 

 residue equal to 1.184 parts, which consisted of .414 parts 

 of asli constituents and .770 parts of organic and volatile 

 matter. 



"One thousand parts of the soil, being treated with hydro- 

 chloric acid of 1.12 specific gravity, produced a solution 

 which contained as follows: 



Potassa 2.3259 parts 



Soda 0.2647 parts 



Lime 6.4283 parts 



Magnesia 2.7237 parts 



Sesquioside of iron, with traces of 



Manganese oxide 44.8332 parts 



Alumina 1 . 4375 parts
