The Mound is "wrop in mystery," that is all about it, and a heap of earth whereof the meaning is not known to the learned is a precious dull spectacle. So, to tell the plain truth, is Thetford. To us the most interesting facts it provided were a substantial tea at the "Bell," itself quite old enough to please. While tea was in preparation we saw quite as much of Thetford as any reasonable man could wish to see; when tea came it was marked by the appearance of weird things in the nature of tea-cakes, combining something of the toughness of the muffin and the texture of dry toast, not very new dry toast, with the shape of the crumpet. The other memory of Thetford is of a strange old man, having toy windmills for sale and attached to every part of his person, after the fashion of those street musicians who, by dint of ingenious contrivances in string, can play, or at any rate make a noise with, some half-dozen rude instruments at the same time. This wandering toy seller was a blessing in disguise. He was, and is, a providential reminder that windmills, here, there, and everywhere, are striking objects in the East Anglian landscape. Travelling eastward from the Midlands one sees them as far west as Buckinghamshire, and there not in the Chilterns only, and in East Anglia proper their name is legion. In or out of working order--and in a country of much wind travelling fast, of water moving, as a rule, very slowly, they are mostly in working order--they add picturesque character to the landscape. Moreover, in beauty they have a distinct advantage over the watermill. The latter may be, often is, exquisite at close quarters; its foaming stream, its dripping and moss covered wheel, its gleaming pond with willow-shadowed or elder-girt bank, are among the loveliest objects in England when seen at close quarters. Your windmill, on the other hand, must in the nature of things be placed either on an eminence or in a wide and open space. Not so beautiful, perhaps, only perhaps, at close quarters, as the watermill, it is still more than pleasing, and it can be seen for miles. It is as a beacon on the coast which the mariner can see for many leagues before he passes it, as the motor-car passes the windmill, at a safe distance. Constable, it is worth while to remember, learned some of his skill in an East Anglian watermill.
