There are two principal veins of fand in this 
diftri@. They are in general red, and of a fharp, 
loofe, gravelly texture, and of courfe not fo fertile 
as the tough, clofe fands of South-Wiltfhire. One 
of thefe runs from Redburn, by Seagry, Draycott, 
and Sutton-Benger, to Langley-Burrell near Chip- 
penham. And another begins at the oppofite cor- 
refponding hill at Charlcot, and runs through 
Bremhill to Bromham. 
From this laft vein, there are two detached maffes 
at Rowd and Seend to the fouth, and probably the 
detached maffes appearing at different plaves to 
the north of it, viz. between Charlcot and Swin- 
don, are parts of the fame vein. 
All thefe detached maffes have a mixture of 
fome other foils, and are generally more fertile 
than the principal veins.. Under the fand land at 
Swindon, lies a fingular rock of ftone of a moft ex- 
cellent quality, ferving equally, in its different beds, 
for the purpofe of building houfes, paving and 
eovering them.
