It is not the energy that wields the spade, guides the plane, 

 or reefs the sail, that is capable of demonstrating or improving 

 these arts. It is a higher power, the culture of the mind ; and 

 this in agriculture, as in every other pursuit, must ever go hand 

 in hand with the culture of the soil. Such has been the rela- 

 tion of science to the progress of art, and such it will forever 

 continue to be : 



" Survey the globe, through every zone, 



From Lima to Japan, 

 In lineaments of light 'tis shown 



That CULTURE makes the man. 

 All that man has, had, hopes, can have, 



Past, promis'd, or possess'd, 

 Are fruits which culture gives or gave 



At industry's behest." 



The science of agriculture has been defined a knowledge of 

 the principles which govern judicious cultivation ; but in truth 

 it is an aggregation of sciences. A youth may soon learn the 

 construction of a steam engine, the principles of its action, to 

 take it apart and put it together, and to direct its fearful en- 

 ergy with his puny arm. But if its mechanism is to be im- 

 proved, and its utility increased, greater attainments, original 

 and independent thought are requisite. So in agriculture, the 

 farmer may soon learn sufficient of the natural sciences, to un- 

 derstand the common arts of cultivation, but their highest im- 

 provement requires a profound knowledge, not merely of one 

 branch, but of many sciences, mutually related and reciprocally 

 dependent. 



In confirmation of this opinion, we cite a few facts of un- 

 doubted authority. We have been favored by a gentleman*' of 

 large attainments and celebrity in the various departments of 

 science, with the results of the analysis of the soil of more than 

 one hundred farms in the state of New Jersey. Some of these 

 may not be uninteresting as felicitous illustrations of the ad- 

 vantages of science applied to agriculture. He analyzed the 

 soil of a field for J. J. Scofield, Morristown, on which he de-
