moderate degree of hardness and strength, but with 
nothing in its appearance to recommend it to favourable 
notice. The private ship-builders therefore declined to 
use it, and as upon trial it was found unsuitable for the 
royal dockyards, none has of late been imported.

Oak timber has also been imported from Spain in 
considerable quantities, for ship-building and other 
purposes. The logs were generally small, or, at the 
best, of only medium dimensions, curved or crooked at 
the butt end, and tapering rather quickly towards the 
top. The wood of the Spanish Oak is of a dark brown 
colour, plain and even in its grain, porous, softer than 
most other Oaks, and liable to excessive shrinkage in 
seasoning.
