In 1857 the Thames Conservancy Board was formed to take theplace of the City Corporation and numerous small companies charged atthat time with the control and upkeep of the Port of London. In 1887a petition by 36 marine companies and insurance agencies was presentedto the Board praying that the channel of the Thames might be deepenedto at least the depth of the Suez Canal. The Board replied to thispetition by making the channel from Yantlet to Crayford Ness 183metres wide and 7 metres 30 deep at the lowest tides, with a channelfrom this point to the Port of London 61 metres wide and 5| metresdeep ! \i <W kl s. t; o s ^ 3 $ H Id 0 N K. 198 SCOTTISH GEOGRAPHICAL MAGAZINE. The lower part ol the Thames remains very much as it always hasbeen, with 9 metres 20 at low water from the Xore Light to Broadness,but above that au altogether insufficient depth. At low water the depthbetween Broadness and Greenhithe is scarcely 6 metres 10, with7 metres 30 to Crawford Xess, 5| metres to Jenningtree, 5 metres 20to Crossness, 5 metres to the Albert Dock, and 3 metres 60 above it. And jet ships are always increasing in size, and only those portswhich are thoroughly equipped and can accommodate large vessels canhope to retain Ocean commerce in future. As a matter of fact, Britainhas allowed other nations to surpass her in regard to the average tonnageof steamers, and now occupies only the fourth rank, coming after Austria,Belgium, and Germany. Her position is even worse as regards sailingvessels, for, in respect to the average tonnage of such ships, Britain holdsonly the seventh place, coming after Germany,
