the mill set to work. It reminded me of the basstns de ckasse, 
in some of our harbours. 
Trematon Castle is situated upon a height. Besides the walls 
furnished with loop-holes which form a quadrangle, the castle 
consists of but two towers, one quadrangular, which forms the 
entrance, and the other a round one, somewhat higher. As 
Mr. Tucker holds this castle of the king, the royal arms are over 
the portal. In the court-yard of the castle, Mr. Tucker has 
built a tasteful house, and, by removing part of the adjacent wall, 
has obtained a beautiful prospect from his dwelling, comprising a 
view of most of the Hamoaze with the shipping, Anthony’s Park, 
Devonport, and part of Plymouth Sound. Mr. Tucker holds 
several important posts in the navy, and during Fox’s ministry 
he was secretary to the admiralty. At the overthrow of that ad¬ 
ministration, he retired to his native place with a pension of 
two thousand pounds per annum, and the office of secretary to 
the duchy of Cornwall; here he is highly esteemed, enjoys great 
influence, and has his property principally vested in the mines. 
After receiving us in a very friendly manner, and introducing 
his family, he took a seat in the carriage. 
We went eight miles further to a silver mine, the only one in 
England. It belongs to a company of five stockholders, of which 
Mr. Tucker is the principal. The country is very hilly, the road 
sometimes narrow and steep, so that it was frequently necessary 
to lock the wheels. A part of the way was over the good road 
from Saltash to Callington; we also passed near to Pentilhe 
castle. The land is generally good, with the exception of a 
heath, of which England contains a number under the name of 
“ commons.” The silver mine is situated in a deep valley of 
Fulliford common. The mine is named St. Vincent, in honour 
of the deceased admiral, who was a great patron of Mr. Tucker. 
The mine has been but five years in progress, and produces so 
little that it sinks two hundred pounds per month for the stock¬ 
holders. The vein of silver, whose presence is judged of cer¬ 
tainly by iron-stone, is cut at right angles by a vein of copper. 
This copper they are breaking through in hopes of greater suc¬ 
cess. The mine has five shafts; the deepest is rather more than 
three hundred feet deep, and serves as a working-shaft: two others 
are used for pumping out the water. One pump is worked by a 
steam-engine of seventy horse-power, the other is worked by a 
compound lever, which is about a quarter of a mile long, 
moved by a water-wheel of forty feet in diameter. The wheel 
is overshot, and the water for working it is obtained from a small 
brook, aided by the water pumped up by the steam machine, 
and conducted to it by a small canal. The lever is composed
