a favorable locality in southern New Jersey, a detailed map of the 

 soils and the crops grown upon them was made in the vicinity of 

 Hartford, Burlington County, N. J., in July and the early part of 

 August, 1914. 



The Hartford area is located along the line of the Amboy Division 

 of the Pennsylvania Eailroad about 12 miles east of Camden. It is 

 adjacent to Rancocas Creek and about 5 miles south of the Delaware 

 River. The area mapped covers about 85 square miles, or 2,259.1 

 acres. It lies within the area of the soil survej^ of the Camden Area, 

 N. J., completed in 1915. 



The Hartford Area occupies a somewhat dissected portion of a 

 relatively flat-topped terrace along the lower course of Rancocas 

 Creek. The surface of thejand rises from the level of the stream in 

 a southwesterly direction to an altitude of 90 feet at a distance of 

 nearly one-half mile from the creek. The area mapped is divided 

 into an eastern and a western division by the deep-cut channel of 

 Parkers Creek which flows across it between steep bounding walls, 

 through a flat-bottomed, marshy valley. 



Thfe altitudes along the railroad, which forms the southern bound- 

 ary of the area mapped, range from 40 to 50 feet above tide level, 

 gently rising toward the center of the upland to an extreme elevation 

 of 80 feet at a point about one-half mile north of Hartford and of 90 

 feet about three-fourths of a mile northwest of Masonville. Aside 

 from the steeper slopes along the banks of Parkers Creek and toward 

 Rancocas Creek, the surface of the area is rolling to gently undulat- 

 ing. Some minor streams have cut small valleys through the up- 

 land and their courses are in some cases bordered by narrow swampy 

 flats. Generally the surface drainage of the area is well established. 

 Small depressions in the surface of the upland might be improved b}^ 

 the installation of tile underdrainage. 



The Hartford area lies within the marl belt of central New Jersey. 

 All of the surface materials are underlain at varying depths by beds 

 of marl ranging from a loose, marly sand to a rather stiff, black 

 marl. The rolling upland is covered by more recent deposits form- 

 ing a part of the more ' elevated terrace intermediate in altitude 

 between the broad terrace which borders the Delaware and the up- 

 lands to the south. The terrace covering varies in thickness from 5 

 or 6 feet down to a thin veneer over the underlying marl formations. 

 East of Parkers Creek the marl formations either reach the surface 

 or are so thinly covered that they form the deeper subsoils and thus 

 give character to the soils mapped in that section. 



In consequence, the soils of the rolling upland in the western part 

 of the area mapped consist chiefly of the Sassafras loam and sandy
