AN ADDRESS, &C. Xvll 



applied to the feeding of stock in the barn yard, and the 

 manure thus obtained be not used to give body and life 

 to the stimulated soil, their expectations of the treasure 

 now dreamt of fiom the use of those substances, will 

 certainly not be realized. But the addition alone of manure 

 will not answer all the desired end of the husbandman; the 

 earth will sicken even of manure: rotations of green fertil- 

 izing or covering crops are indispensably necessary to reco- 

 ver the earth from the exhausting effects of an uninterrupt- 

 ed cultivation of tobacco and grain, or of any one crop.— 

 This is not mere theory; the experience of every judicious 

 farmer or cultivator in Pennsylvania, will support me in the 

 propriety of this injunction.* 



The importance of good roads and canals to all countries, 

 in facilitating the cheap and constant transmission of the pro- 

 ducts of agriculture and of labour generally, is so obvious, 

 and has been so fully ascertained by the experience of Eu- 

 rope; that the subject cannot be too often, nor too forcibly 

 impressed upon the attention of the public They mark the 

 genius, spirit, enterprize and good sense of a people, and are 

 indissoluble connected with individual comfort, and national 

 wealth. During the continuance of the universal war that 

 recently vexed the European world, such was the profitable 

 external commerce enjoyed by <he United States previously 

 to their entering into the war. that it. was impossible for some 

 time to convince the people or legislators, notwithstanding 

 the able papers written on the occasion, of the infinitely 

 greater value of internal commerce and of a home market, 

 than of foreign trade; and although it was frequently pre- 



* As the knowledge of the most judicious modi of applying the substan- 

 ces mentioned to the soil, is of consequence, the socieU will thankfully re- 

 ceive communications on the subject; and in their na,me I beg leave to re- 

 quest them,
