From Sail to Steam - Caroline Williams

Waterloo saw the end of Bonaparte and of the blockade of trade with Europe. None saw more benefit than the Channel Islanders and for the next half century they developed a lucrative, world-wide carrying trade which built fortunes in St Helier and St Peter Port for ship-builders, ship-owners and mariners. From about 1865 those trades declined . Guernsey diversified into stone quarrying, whilst Jersey developed the export of the new potato and tourism. This significant contribution to the history of the islands compares the impact of the expansion.
