These experiments, it isthue, are not easy; stili, they are in the power of evert 
thinking husbandman. he who accomplishes but one, of however limited application, and 
takes care to rei oht it faithfully, advances the science, and, consequkntly, the practice 
of aoriculture, and acquires thereby a eiobt 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 pkepahe the forms of such experiments, and to distribute the execution of these 
among their members.
