The export that comes next in value is silk, and after it may be named wheat, barley, manganese ore, maize, wool, oilcake, carpets, rye, oats, liquorice and timber.
This removal of the shell makes a great difference in the oilcake, as the decorticated cake is more nutritious than the undecorticated.
There are several factories for pressing cotton, and for cleaning coffee, oilcake presses, tanneries and saltpetre refineries.
The principal articles of export are cereals, with some oilcake, phosphate and coal; but the total value is only about £2,000,000 annually.
Livonia carries on a large export trade, especially through Riga and Pernau, in petroleum, wool, oilcake, flax, linseed, hemp, grain, timber and wooden wares; the Dvina is the chief channel for this trade.
