In all this course of study you will be much facilitated by the remembrance of your practical office work. You will remember puzzling questions which have occurred to you while making working details, and watch to find them solved in original work. How is the gable of an aisle connected with the eaves? and how with the parapet? How are timber overhanging eaves brought in contact with a stone gable? and how is the same done with stone eaves, or where the eaves are wood, and the roof timbers show through the gable?[67] All sorts of little questions such as these will have occurred to you in practice, and rested as doubtful points on your minds, but may be solved in many natural and pleasant ways while travelling among old examples--except, indeed, where the modern “restorer,” innocent as a babe of all such doubts, has levelled everything to his own office tariff. In such tours, be most careful accurately to sketch all the _scarcer_ classes of examples you meet with, such as remnants of thirteenth and fourteenth century roofs and other wood-work, fragments of painted glass, specimens of iron-work, early screens and stalls, choice specimens of carved foliage or figure sculpture, traces of wall decorations, illuminations of screens, etc., and colouring on roofs. The unsparing hand of the so-called restorer has devastated and is still eagerly devastating whole districts, and clearing them of these invaluable records of ancient art; and this alone, independently of their high intrinsic value, renders it doubly important that the few remaining relics should be carefully represented. And be it ever remembered that such representations, to be really valuable, should not be mere hasty memoranda, but, if possible, careful measured drawings. I have hitherto supposed your sketching expedition to be one of a purely rural kind, and the examples from which you study to be mainly on the scale which we find in villages. I will now transfer the imaginary tourist to the opposite extreme, and suppose him to be devoting himself to one of our greatest cathedrals, as, for example, _Lincoln_. Here the case is greatly changed, for he will get no great good unless he seats himself down, determinedly and long, and goes through a lengthened course of careful and minute study, not necessarily of the entire cathedral, but at least of the parts selected for special attention. It is best at once, on your arrival, to take lodgings near at hand, and to enter into some arrangement with the verger for your admission at all reasonable hours, obtaining, if needful, a _carte blanche_ from the authorities to go where you like, and at proper times to do what you like.
