Old Fields. 



Cultivated areas when neglected for a few years are quickly seeded to 

 pine. In the northern part of the county scrub pine is the common 

 growth, while in the southern end the loblolly often predominates. 

 Scrub pine is, however, the common and characteristic growth of the 

 old fields. These are found in all parts of the county and usually on 

 the upper slope above streams. It is a fairly common practice to allow 

 fields to rest in this way for a number of years when they are again 

 cleared of pine and eullivated. For this reason (lie old fields have been 

 included in the agricultural areas. The following tables give an idea 

 of tlie older stand on tliese once cultivated areas. The first table shows 

 a stand of scrub pine, the second one of loblolly pine.
