early truck crops and peaches. The latter crop wlien raised on the 

 Windsor sand produces a superior quality of fruit both in color and taste, 

 and the orchards found on this soil in other localities are long lived, 

 healthy, and profitable. 



The Windsor sand areas of St. Mary's County are all located within 

 easy hauling distance of the present railroad points, and special crops 

 of early fruits, vegetables, and peaches could find an easy and profitable 

 market in the cities on connecting lines. 



The surface of the Windsor sand is generally level and is little sub- 



ject to washing on account of the porosity of the soil. It is easily 

 cultivated and easily improved, and should form a valuable type for 

 the special crops already discussed. 



The above analj-ses show the texture of typical samples of the soil and 

 subsoil. 



The Norfolk Sand. 

 The Norfolk sand illustrates the fact that a single soil type may arise 

 from materials deposited at different geological periods. In St. ]\Iary''s 

 County, soil of this type is found along the sloping sides of streams as 

 an outcrop of some of the basal formations of the county; again it occurs 

 along the lower courses of these streams as flat-topped terraces built 

 up from the older material by river transportation; while small areas 

 of it occur along the forelands as material carried still farther seaward.
