AGRICULTURE WITH CHEMISTRY. 8: 



SULPIIAT OF SODA, OR GLAUBER SALT. 



Glauber Salt is soluble in about two and one half 

 times its weight of cold water. From experiments, it 

 has been proved to promote vegetation in a very nigh 

 degree. It is procured in small quantities, in the pro- 

 cesses for making the muriatic acid, and muriat of 

 ammoniac, or sal ammoniac. The high price at present of 

 this article precludes the use af it ; but could it be made 

 and sold at a cheap rate, it would prove a most valuable 

 acquisition to Agriculture. 



SULPIIAT OF AMMONIAC OR VITRIOLIC AMMONIAC. 



This salt is very soluble, and promotes vegetation; 

 but it is not to be had in such quantities as to render it 

 ■an article of importance to Agriculture.
