Tur main high-level coal-fields of South Africa have an extreme 
length from north to south of not less than 400 miles; the breadth 
at the widest part is over 200 miles, but the average breadth is 
about 140 miles ; therefore the coal-fields cover, wholly or in part, 
an area of about 56,000 square miles. The map (fig. 1) is in-
