VIEW DOWN THE THAMES, FROM LONDON BRIDGE.
That part of the Port of London seen from London Bridge, looking down stream, is known as the Pool, and it generally contains craft of all kinds, great and small, though barges predominate. Altogether, it is a very busy scene. To the extreme left of our picture the front of Billingsgate Market, the headquarters of the English fish trade, is partly visible. Billingsgate Wharf is the oldest on the Thames. Just east of the Market is the noble fašade of the Customs House, with its broad quay in front; while further down will be recognised the ancient Tower of London. We have already given a closer view of the Customs House, on page 8; and of the Tower of London, on page 22.
