Approximately one-half of the total area mapped is used for the 

 growing of general farm crops and truck crops; the remainder is in 

 forest, gardens and grounds, orchards, and the experimental plots, or 

 else is unoccupied for farming purposes. 



The truck crops occupy about one-third of the total area, both in 

 fall and in spring. Among these crops, strawberries cover the largest 

 acreage, except during the winter months, when the acreage in spin- 

 ach is slightly larger. 



The considerable acreage given to cabbage growing is notable. 



The subordinate position of potatoes in both spring and fall and of 

 kale among the fall crops is marked. 



The growing of snap beans, interplanted with strawberries, is a 

 feature of the cropping on the coarse sandy loam soils. 



The relatively large area given to forage and grain crops in the 

 spring is in somewhat marked contrast with the conditions shown by 

 the June crop map of the Churchland area. The larger area of heavy 

 soils in the Diamond Springs area accounts for this, in part. The 

 fact that corn frequently succeeds spinach, cabbage, and such straw- 

 berry beds as are plowed out after finishing their bearing period also 

 influences the acreage of corn. 



Comparison of the Churchland and Diamond Springs Areas. 



Although the Churchland and Diamond Springs areas lie within a 

 few miles of each other, under closely similar climatic conditions and 

 with almost equal accessibility to shipping points, the two areas 

 show some notable contrasts in the character of cultivation, especi- 

 ally with respect to the growing of truck crops. 



The Churchland area is dominated by fine sandy loam soils which 

 occupy over 95 per cent of its total area. The Diamond Springs area 

 is marked by a considerable diversity of soil types. The loam soils 

 cover 42 per cent of the total area; gravelly loams occupy 18 per cent; 

 coarse sandy loams cover 30 per cent, and one fine sandy loam soil 

 comprises but 8 per cent of the total area mapped. Thus, nearly 60 

 per cent of the total area consists of rather heavy soils. 



In the Churchland area two-thirds of the upland area consists 

 of naturally well-drained soils, while the other types have been 

 decidedly modified with regard to drainage by the tile underdrainage. 

 The soils of the Diamond Springs area may be grouped into three 

 classes with respect to their natural drainage. The Sassafras loam, 

 fine sandy loam, and coarse sandy loam and the Norfolk coarse 

 sandy loam are naturally well drained. These four types occupy 

 43 per cent of the total area. The Norfolk loam and gravelly loam 

 are only moderately well drained in their natural condition, and 

 little artificial drainage has been installed. They cover 40 per cent 

 of the total area. The Suffolk loam and gravelly loam are dis-
