These experiments, it is trde, are not easy; still they are in the power of every 
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 agriculture, and acquires thereby a right to the gratitude of nls 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 the execution of 
these among their members.
