This book covers Turner's journey from Morlaix, on the north coast of Brittany, to Nantes, near the estuary of the Loire. It does not seem that he made many sketches between Mont St-Michel and his arrival in Morlaix. Those that can be identified are his annotations on his map of Brittany (no.10). Perhaps because of unsettled weather, his method of sketching was not as attentive and careful as on earlier tours, at least until he got as far as Nantes. For example, given the slightness of this sketch of the harbour at Brest, it is remarkable that Turner should have thought of using it as the basis for the large oil painting hanging nearby (no.99).
