These experiments, it is true, are xot easv ; still they are in the power of evert 
thinking hcsbandman. he who accomplishes but one, of however limited application, and 
takes cake to report it faithfully, advances the science, and, consequently, the practice 
of agriculture, and acquires thereby a bight 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 societies formed for the improvement of our science 
.should be to prepare the forms of such experiments, and to distribute the execution op 
these among their members.
