takes care to retort it faithfirllt, advances the sciexce, and, consequently, the prac- 
tice of agriculture, and acquires thereby a right to the oratrtude of his feiiows, 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 distributl 
the execution of these among their members.
