These experiments, it is tude, are sot easy ; still they aue in the poweb of every 
thinking husbandman. he who accomplishes but one, of however uillted application, and 
takes care to report it faithfully, advances the science, and, consequently, the prac- 
tice 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 care of all socikties formed for the improvement 
op our science should be to prepare the forms of such experiments, and to distbibctb 
the execution op thibe among their mejibers.
