Riga Timber is like the other varieties just described, but the annual rings are closer.
It is slightly inferior to Dantzic in strength, is remarkable for its straight growth, for the small proportion of sap it contains, and for its freedom from knots. It is, however, frequently a little shaky at the centre, and is therefore not so fit for conversion into deals as other varieties.
This timber is only once sorted for masts before it is exported, and is placed in the market without the brands described on p. 384.
Norway Timber is of small size, tough, and durable, but it generally contains a good deal of sapwood.
The balks are only about 8 or 9 inches square.
Swedish Timber somewhat resembles that from the Prussian ports, but the balks are generally tapering in form, of small size, and not of good quality.
The wood is of a yellowish-white colour, soft, clean, and straight in grain, with small knots and very little sap, but the balks are generally shaky at the heart, and therefore unfit for conversion into deals.
Mr. Laslett says - "There is little to recommend the Swedish fir to favourable notice beyond the fact of its being cheap and suitable for the coarser purposes in carpentry."
It is used chiefly for scaffolding.
Market forms. - The balks are generally from 20 to 35 feet long, and from 10 to 12 inches square.
