These experiments, it is true, axe not easy ; still they ake in the power of every 

 thinking husbandman. he who accomplishes but one, of however limited application, and 

 takes care to rei'ort it faithfully, advances the science, and, consequently, the practice 

 of agriculture, and acquires thereby a right to the gratitude of his fellows, and of those 

 who come after. to make many such is beyond the power of most individuals, and cannot 

 be expected. the first care of all societies formed for the improvement of our science 

 should be to prepare the forms of such experiments, and to distribute th e execution of these 

 amonqtheir members.
