These expekiments, it is tkue, ake not east; still tiiei are in the power of evert 
7htkkinq husbandman. he who accomplishes but one, of however limited application, and 
tates care to report it faithfully, advances the science, and, consequextlt, the pbactice 
op agriculture, and acquires thereby a eight to the gratitude of his fellows, and of those 
who come after. to make many such is beyond the power of most indh iduals, and cannot 
be expected. the first care of all societies formed for the improvement of ocr science 
jho'jld be to prepare the forms op such experiments, and to distiubcte the execution op 
these among their members.
