This is surmounted by abrick building in which is the machinery for working the power is furnished by a turbine at one end of the buildingwhich acts directly to turn a long horizontal shaft runninglengthwise of the building above the gates. Each of the latterhas two vertical wooden posts (stems), 10 by 13 inches in size,fastened to it, and faced on one side with iron racks. Thelong shaft operated by the turbine, in turn, by connectingbelts, causes a series of cog-wheels to revolve, the last of theseengaging and moving the racks ahead}- mentioned and withthem the gates, each of which can be moved independently ofevery other. Commonly the water stands higher outside thegates than in the canal; at such times they are not raised
