Its principal industrial establishments are mechanical works (both in the city and at Lundby), saw-mills, dealing with the timber which is brought down the Gota, flour-mills, margarine factories, breweries and distilleries, tobacco works, cotton mills, dyeing and bleaching works (at Levanten in the vicinity), furniture factories, paper and leather works, and shipbuilding yards.
The prosperity of the French shipping trade is hampered, by the costliness of shipbuilding and by the scarcity of outward-bound cargo.
Other thriving industries include bleaching, dyeing, calico-printing, weaving (carpets, shawls, tartans), engineering, tanning, iron and brass founding, brewing, distilling, and the making of starch, cornflour, soap, marmalade and other preserves, besides some shipbuilding in the yards on the left bank of the White Cart.
Imports include coal,timber, tar and hemp. Steam sawing, metal-founding, fish-salting, shipbuilding and repairing, and the manufacture of ship's-biscuits and fishing-nets are among the industries.
There are large collieries in the neighbourhood of the town, the workings in some cases extending beneath the sea, and blastfurnaces, engineering works, cycle and motor works, shipbuilding yards and paper mills.
There are smaller arsenals at Para, Pernambuco, Sao Salvador and Ladario (Matto Grosso) and a shipbuilding yard of considerable importance at the Rio de Janeiro arsenal.
Linen and woollen fabrics, hosiery, paper, cigars, soap, vinegar and earthenware are manufactured, and there are iron-foundries, distilleries, tanneries and shipbuilding yards.
The chief business is in butter, eggs, cattle and pigs, while bleaching, dyeing and shipbuilding are also carried on here.
All the great iron foundries and engineering works are situated in the Central Plain or Lowlands, in close proximity to the shipbuilding yards and coalfields, especially in the lower and part of the middle wards of Lanarkshire, in certain districts of Ayrshire and Renfrewshire, at and near Dumbarton, in south Stirlingshire and in some parts of East and Mid Lothian and Fife.
Among the new manufactories were a shipbuilding establishment at Groton near New London, which undertook contracts for the United States government, and a compressed-air plant near Norwich.
