island, the second of the Channel Islands in point of 
X size, is in the form of an isosceles triangle, its eastern 
and southern sides being each about seven miles in length ; the 
western, the most indented side, is nearly ten miles long ; its 
area is twenty- three square miles. 
The southern portion, which resembles in many respects the 
south coast of Cornwall, is mountainous, attaining in some 
parts an elevation of nearly 400 feet above the sea, and forms a 
plateau, gradually declining to the north about half way across 
the island ; the northern part is flat, diversified by irregular hills 
of no great elevation. The geological formation of the northern 
part is Syenite, of the south Gneiss, which is traversed by large 
seams of hornblende, called in the locality “ Trap Dykes.” The 
Syenite, or Guernsey granite, is largely quarried, and forms the 
principal article of export, not less than j^38,345 tons having 
been shipped in 1879, and a similar quantity the previous year. 
It is preferred on account of its extreme hardness, and is 
exported in rough pieces to be broken in England — in spalls ready 
for Macadamizing, in blocks for pitching, and prepared for kerbs. 
Valuing it at 6s. per ton, the annual return from this source 
alone is £70,000. . 
The export trade of the island is almost entirely confined to 
England, and includes, beside the granite, vegetables (potatoes,
