 A heavy sea from the Indian Ocean is always breaking on the shore, even in the finest weather, and at the mouth of every natural harbour a bar occurs.To deepen the channel over the bar at Durban so that steamers might enter the harbour was the cause of labour and expenditure for many years.Harbour works were begun in 1857, piers and jetties were constructed, dredgers imported, and controversy raged over the various schemes for harbour improvement.
