Some interest is awakened in engineering circles in London, just now, by
the approaching close of the old engineering works so well known as the
"Canal Ironworks," at the entrance to the Isle of Dogs, London, E. This
notable establishment stands second in priority in London--that of
Messrs. Maudslay, Sons & Field being the oldest--for the manufacture of
marine engines. It was founded by the late Messrs. Seawards, above sixty
years ago. Here was originated Seaward's hoisting "sheers" with the
traveling back leg, a modern example of which, 100 feet high, in iron,
stands on the wharf. An interesting tool, also, is the large vertical
boring machine for largest size cylinders; Seaward spent £5,000 upon
this, and it is certainly an admirable tool. There is also the large
vertical slotting machine, with a stroke up to 5 feet 2 inches, a
wonderfully powerful and compact machine. The extensive collection of
screwing tackle is, perhaps, unsurpassed, and extends up to 8 inches
diameter. There is a peculiar erecting shop roof, which will still repay
examination.
