 time, we may avail ourselves (and it may perhaps be 

 a very long time) of the united efficacy of gypsum and 

 clover. 



I said that we had much to do before we attained 

 that degree of perfection which was practicable in 

 agriculture. 1 presume, that our lands, in their natu- 

 ral state, were full as good as those of England. In 

 England, the average crops of grain of all kinds, on 

 8,000,000 of acres, are estimated at twenty-four bush-

 clair, who says, moreover, that in ^^ fertile districts 

 and propitious seasons, from thirty-two to forty bush- 

 els of wheat an acre, may be confidently expected ; 

 from forty-tw^o to fifty of barley, from fifty-two to 

 sixty-four of oats, and from twenty-eight to thirty-two 

 of beans.'^ The best county in Pennsylvania, is sup- 

 posed to be Lancaster. The matter cannot be spo- 

 ken of with any kind of certainty ; but, from the best 

 information I have been able to collect, 1 should doubt 

 whether the wJieat crops of the whole county of Lan- 

 caster, averaged more than fifteen bushels an acre, 

 though many individual farmers get from twenty to 

 thirty; and some from thirty to forty. But, when we
