These experiments.it is true, akk not easy; stij.l they are in the power of every 

 thinking husbandman. he who accomplishes but one, of howe ver limited application, and 

 takes care to report it faithfully, advances the sciencx, and, consequently, the practice 

 op agriculture, and acquires thereby a right to the gratitude of his fellows, and of thosk 

 who come aktek. 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 of thesk 

 amongtheir members.
