These experments, it is true, are kot 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 

 op 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 op most individuals, and cannot 

 be expected. the first cake of all societies foriied for the improvement op our science 

 should be to prepare the forms of sdch experiments, and to distrrbute the execution of 

 these among their members.
