4 



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 high 

 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 of it; but could it be made 

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

 acquisition to Agriculture.
