In November 1805, I planted 311 trees adjoining 

 to no. 4, at 30 feet apart. The ground had previously 

 been in corn the holes were prepared in the same 

 manner many of the trees were large, had been trans- 

 planted a second time into a rich strong soil. I mixed 

 no stable dung with the compost, which was made of 

 river mud, ashes, and some lime ; this I put round 

 the trees on the surface, a wagon load to ten trees 

 although corn is generally thought an exhausting crop, 

 I continued it under that culture for three successive 

 years, except a part, which, during the same time, has 

 been occupied as a vine and garden patch. These 

 trees have grown with a vigour which I never saw 

 equalled : in two years but one has died, and that

 the quality of the manure, have in my opinion, united 

 to produce the flourishing state of these trees I cannot 

 discover any difference between the trees transplanted 

 once and twice, in this or any other of my plantations, 

 where the sizes were originally the same. In
