While he and his relatives returned across the ferry to Stonehouse, we went to see the steam floating bridge, similar to that used between Portsmouth and Gosport.  We much wished that we had had time to pull up the Tamar, the scenery of which is highly picturesque.  Small steamboats run up it a considerable distance, and carry excursionists.  We went some distance up, to see the beautiful iron bridge which spans it, as also to have a look at the Oreston quarries, from which the material for forming the breakwater was principally procured.
