These experiments, it is true, are not easy; stii-l thev ars in the power of everv 

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

 takes care to report it faithfully, advances the science, and, consequently, the practice 

 of aoricitltube, 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 socie'nes formed for the improvement of our science 

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

 among their members.
