ABSTRACT
The town of Truro, which now contains about 10,000 inhabitants, is situated on the declivities of two hills, and on a central platform between them. The tide ascends into the channels of each a little beyond those bridges, which cross them at the lowest point of their course. The division of Truro to the north-east of St. Mary’s lies in the parish offset. Clement, and is placed in part on the side of a generally steep acclivity, in part on the flat between its foot and the river. The tide ways are filled with an extensive alluvium, which is only traversed by the small fresh-water rivers during the greater part of the day, but is completely covered at high water, at neap as well as at spring tides. It is rare that any offensive odour is perceived from these mud banks, though hydrogen and its usual compounds are emitted on their being disturbed.
