confcquently a freer admiflion given to the air, which I 

 have fince found to be neccflary in the culture of every 

 article of the leguminous kind. When the crop was 

 thraflied, I had one firlot more beans upon No. i . than 

 upon No. i ; and No. 3. only returned me the fame pro- 

 duce avS No. I, tliou;h it contained feveral more drills ; 

 befides, owing to the double rows, it was nothing like fo 

 well cleaned. The inferences which I drew at the time, 

 and which have fince guided my condu£l in this branch 

 of hufbandry, were, ift. That a certain portion of air 

 was required to bring beans to perfection \ and that the 

 quantity to be procured, when the intervals were only 18 

 or 20 inches, was not fufficient for that purpofe. 2d, 

 That intervals lefs than 2 7 inches would not admit tKe 

 full benefit of ploughing, which is a chief obje£t in the 

 drill hufbandry : And, laftly, That double rovv's, with 

 wide intervals, were not advantageous, as they neither re- 

 turned a greater produce, nor allov/ed the ground to be 

 fo well cleaned as fingle rovv'S. 



I have, fince the above trial, uniformly drilled beans 

 upon a gi'eat fcale, according to the firft mentioned me- 

 thod, with this fingle alteration, that the hand-hoe is laid 

 afide, and the whole operations performed by horfe la- 

 bour. The different ploughings are given with one horfe, 

 and are repeated according to the nature of the foil, and 

 the drynefs of the weather. This is the cheapcft and 

 moft effeflual way of cultivating beans : and indeed it is 

 How very generally pra£tifed. I am, &c.
