is better than or opposed to scientific investigation is a 

 sophist, "and the truth is not in him," because scientific 

 investigation is experience, is not opposed to, but harmonizes 

 with it, is not less, but rather greater than ordinary expe- 

 rience, since it expressly seeks to winnow away the error it

If any one lets alone the results of scientific investigation, 

 to depend upon ordinary experience, he lets alone the oldest,

 asserting a thing, there denying it; now believing, now skep- 

 tical. But scientific experience is that whereon one may most 

 surely rest, for it reveals the changeless and perfect laws, in 

 whose obedience Nature glorifies her Author.

 source whence mine is derived. He asserts that "the experi- 

 ments made by farmers with this guano prove it to be the 

 most valuable fertilizer ever brought into this country." I 

 am prepared to show the experience of agriculture has not 

 proved this statement true. I am confident that overwhelm- 

 ing evidence can be produced to the contrary, and am ready 

 to discuss that point with him or any one. Your correspond- 

 ent believes that the natural comMnation of the phosphates 

 and sulphates of lime, is a reason why the American guano
