The pictorial illustrations have been prepared with care, and will give the reader, who is not disposed to traverse the ground, a correct idea of the state of the Barrier. The wood-cuts and plates, illustrative of the antiquities found on the line, have, with the exception of a few coins introduced into the first Part of the volume, and copied from the MONUMENTA HISTORICA, been prepared from original drawings, taken for this work from the objects themselves. I am not without hope that the well-read antiquary will value these delineations for their beauty and accuracy. The inhabitants of the isthmus are proud of the Wall and its associations; and whatever may have been the case with their forefathers, will not needlessly destroy it. Most kind has been the reception I have met with in my peregrinations, and most valuable the assistance I have received from the gentry and yeomen of the line, and others interested in my labours! Gladly would I enumerate all to whom I am indebted, had it been possible. Some names, however, must be mentioned. His Grace the Duke of Northumberland has not only given me free access to all his antiquarian stores, but directed me to prepare at his expense engravings on wood of all that I thought suitable to my purpose. Would that his Grace knew how much I have been cheered in my course by his notice of my humble labours! To John Clayton, esq., I am obliged for the gift of the wood-cuts illustrative of the numerous and interesting antiquities preserved at CILURNUM, the produce of that station and BORCOVICUS. To Albert Way, esq., the accomplished and honorary secretary of the Archæological Institute, with whom I had last year the pleasure and advantage of spending a day upon the Wall, I am indebted for the cuts representing the altar and slab discovered at Tynemouth. The suite of wood-cuts illustrative of the hoard of coins found in the ancient quarry on Barcombe-hill, have been engraved at the expense of my tried and valued friend, John Fenwick, esq., of Newcastle-upon-Tyne; and to William Kell, esq., town-clerk of Gateshead, with whom I have traversed the Wall from sea to sea, and some portions of it repeatedly, I am indebted for the beautiful representation of the ancient PONS ÆLII fronting the title-page. My former school-fellow, William Woodman, esq., town-clerk of Morpeth, besides otherwise assisting me, has caused surveys to be made for my use of not fewer than eighty of the strongholds of the Britons still existing on the heights north of the Wall. To trace the movements of the brave people whom the Romans drove to the more inaccessible portions of the island, would have been an interesting sequel to the account of the Roman Wall, but I found the undertaking too great for me.
