These experiments, it is true, are not easy; stitx they are in the power of every 

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

 takes care to report it faithfttlly, 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 c4re 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.
