Among the _Southern Coast_ sketch-books is a fat little volume bound in brown calf, having a brass clasp and lettered on the back, _British Itenary (sic)_. The title page runs as follows:--_The British Itinerary_ | or | Travellers Pocket Companion | throughout | Great Britain | Exhibiting | the Direct Route to Every | Borough and Commercial Town | in the Kingdom | with the principal Cross Roads | Compiled from Actual Measurement | and the best Surveys and Authorities | By | Nathanl. Coltman; | Surveyor. | Employed by the Post Office in Measuring the Roads of | Great Britain | London. | Printed and Published, by Wm. Dickie, No. 120 Strand; and N. Coltman, Green Walk; Black Friars Road. | Price 3s. Sewed.’ It contains two hundred and fifty leaves, the printed matter only occupying about a third of the total number, the remainder having been left blank for notes. These are now filled with Turner’s notes of expenses incurred, the draft of the poem he attempted to write, and a number of minute sketches. Among these it is possible to recognise the originals of several of the _Southern Coast_ designs, including those of Combe Martin, Watchet, Boscastle and Clovelly, the ‘Dartmouth’ and ‘Dartmouth Castle’ of the _Rivers of England_ series, and the sketch upon which the superb ‘Stonehenge at Daybreak’ (R. 81), in the unpublished ‘Liber,’ was probably founded. Two of these sketches have been reproduced on Plates LV. and LVI., together with the engravings of the completed designs. That the finished drawings could have been made from such slender material can hardly appear less than astonishing to those familiar with the methods of artists of the present day; but to the best of my belief, Turner had no other sketches or drawings of these places to assist him in his work, and it can only add to our amazement when we notice that in all probability the finished drawings were made, one nearly eight years, and the other nearly fourteen years, after the sketches were taken; the ‘Watchet’ plate having been published in April 1820, and the ‘Boscastle’ in March 1825.
