The refults of the gypfum perches fufficiently 

 prove that it operates as forcibly on this plant as 

 upon fainfoin, with refpeft to grofs produft; but the 

 value of Dutch clover (eed being fo fuperior to that 

 of fainfoin, has occafioned the money value of the 

 feed produft A. to exceed the highefl fainfoin feed 

 product No. 2, as 3 to I ; and upon deducing the 

 grofs natural produft a from the gypfum produft 

 A, it will appear that there is an abfolute gain of 

 14I. 2S. 3d. per acre, at the expence only of i6s. 6d. 

 for fix bufliels of gypfum. The invariable refults of 

 the feveral experiments, which are faithfully, and I 

 trull corre£lly ftated, do, I think, inconteflibly prove 

 that there is a mod powerful and fubtile principle in 

 this taftelefs (lone; but by what peculiar agency or 

 combination it is capable of forcing vegetation in fuch 

 an inllantaneous and allonilliing manner, is a myftery 

 which time rcferves for a ***** or a ****** to 

 unfold. But until this period arrive, the practical and 

 }nolt cautious farmer will, I hope, run no great 

 hazard in venturing fome fmall trials on the credit of 

 tlie above matters of faft, which I have faithfully 

 . and truly flated. Art.
