 neath the surface, and will keep much better; indeed I 

 find them to keep quite as well as any other sort; but 

 this was not the case, until I adopted the plan I have 

 described. 



Having said thus much on Underground Onions, I am 

 tempted to give you the result of three different trials of 

 growing Common Onions, which I made this year, for my 

 own satisfaction; and as my mind has been thoroughly 

 convinced as to the best method, it may be useful to 

 give the particulars. I claim no merit in what I have 

 done; but I think it is of great advantage, repeatedly to

 been previously made known, but have been suffered to pass 

 by unheeded. 



My first mode was with the small bulbs of Portugal

 very good crop ; but not to be compared to the first, which
