 easily cultivated, the Hawthorn has been neglected.

Obs. This species is the one which has been chiefly cultivated for 

 hedging, in this County, where it was introduced, from the vicinity 

 of Washington City, about the commencement of the present cen- 

 tury. It makes a handsome hedge, when well managed ; but not 

 so substantial and effective as the Cockspur Thorn. It is so subject 

 to be injured, and broken into gaps, by thoughtless and reckless 

 trespassers especially near villages that the attempt to cultivate 

 it is rather a source of vexation, than of satisfaction.

06*. There appears to be two pretty distinct varieties of this; 

 both of which, however, are so rare, that I am not quite sure they 

 are truly indigenous here. The Cock-spur Thorn, in my judgment, 

 is decidedly the best for making a durable and effective hedge : But, 

 until timber shall become scarce, very few farmers will take the 

 requisite pains to insure a complete hedge, and without such 

 care, it is worse than labor lost to make the attempt. In the lan- 

 guage of Mr. M'MAHON'S excellent " American Gardener's Calendar" 

 referring to the hedging experiments of negligent, slovenly farmers : 

 " I would advise such to hold fast by the post and rail, and not to 

 lose time in doing more harm than good."
