These experiments, it is true, are not easv ; still they are in' the power op evert 
ihixking husbandman. he who acc05iplishes uut one, of however limited application, and 
takes care to report it faithfullt, advances the science, and, conseqcentlt, the practice 
op agriculture, axd acquires theredt a right to the gratitude of his fellows, and of those 
who come after. to make 5iany such is beyond the power of most inon lduals, and cannot 
ee expected. the first care op all socteties formed for the improvement of ocr science 
should be to prepare the forms of such experiments, and to distribute the execution op 
these among their members.
