On the outskirts of Bollington, the canal passes another Clarence Mill, another huge building which now houses small industrial units. Two aqueducts and a embankment carry the canal over the valley of the River Dean and into Bollington. Adelphi Mill is on the west bank at the southern edge of Bollington, and was once a silk mill. It has been converted for use as offices. After another rural section, the canal enters Macclesfield. Hovis Mill, where the famous flour was originally milled, is on the west bank. It was built in the 1820s, and has been converted into apartments. A branch of the canal formerly led into the complex, but only its blocked up entrance remains. Near Gurnett Aqueduct, which carries the canal over the road to Gurnett and the River Bollin, is a cottage with a plaque to commemorate the civil engineer and canal builder James Brindley. He served an apprenticeship to Abraham Bennett between 1733 and 1740 there.
