texture to the Bermudian, and is well adapted for the 
same kind of employment. 
The Spaniards formerly used Cedar to a great 
extent in ship-building ; and the “Gibraltar” and other 
large ships of theirs were found, on being taken to 
pieces, to have much of this wood in them, in a sound 
state. 
Cedar is found in India, Japan, Australia, and Van 
Diemen’s Land. 
The same rule prevails in the market with reference 
to the sale of Cedar as with Mahogany, namely, that of 
deducting about one-third from the calliper measure¬ 
ment for irregularity of manufacture, shakes, defects, 
centres, saw-kerfs, &c. 
Pencil Cedar is classed No. 3 ; Red Cedar, No. 6 ; 
and White Cedar, No. 17, among timbers used in ships, 
in Lloyds’ rules for ship-building.
