up wholly of clay or of sand particles. All soils contain 

 a certain per cent of each of these groups of fine particles. 

 The coarser sandy soil drains more rapidly, warms up 

 more quickly in the spring and is, therefore, better suited 

 to early garden or truck crops. Clay soil dries out more 

 slowly, and for this reason it is capable of furnishing water 

 to the crop during the hot dry summer months, especially 

 if it contains a large amount of organic matter.
