•58 CATALOGUE OF TREES AND SHRUBS 



Conedoguinet creek, the timber grows to a very large size. It is not 

 uncommon to see Buttouwoods seven feet, Mossycup oaks five feet, and 

 Hackberries two feet in diameter, Grape vines, and the Viburnum pru- 

 nifoliuni, 6 to 8 inches. About 7 miles to the south-west of Carlisle, 

 there is a strip of woods called the Richlands, containing trees of an 

 astonishing diameter and height, so high indeed that it is considered an 

 almost impossible feat to kill a squirrel or wild pigeon on the top, with 

 shot. The slate land is very unproductive compared with the limestone, 

 though by good management it affords a tolerable yield. The North 

 mountain is very rocky along its sides, fertile, however, on parts of its 

 top. 



The most peculiar part of the County consists of that portion of it 

 in the South mountain. This is not a single range like the North moun- 

 tain, but occupies an area of considerable breadth, made up of short 

 hills and ridges, separated by narrow vallies, and copiously supplied with 

 springs and swamps. In these latter, we find the Cranberry and fragrant 

 Magnolia growing in abundance, particularly in one called the Black 

 Swamp, near Pinegrove furnace. 



By a comparison of this list with that contained in Darlington's 

 Flora Cestrica, it will be found that many of our species of oak, maple, 

 cherry, currant, hazel, &c, are wanting in Chester County. Others com- 

 mon here, are rare there. Again, there are a few found there in which 

 we are deficient. Of these latter the majority will most probably be 

 found hereafter, as the species named below are the collection of a single 

 season, and of a single individual. Several still remain undetermined, 

 for want of satisfactory specimens. It will be observed that the whole 

 genus Salix is omitted, the collection having been commenced too late 

 in the spring to get them in flower. 



The nomenclature employed is principally that of Torrey and Gray, 

 in the North American Botany, Torrey in the Report on the plants of 

 New York, and in some instances Darlington in the Flora Cestrica. 

 We add the synonyms of this latter work, when they differ from the 

 name we have adopted.
