Now Mr L asks me about the glide, which I have mentioned but not sufficiently described. The glide, such as one sees at Stanway, and most famously at Chatsworth, is difficult to bring off because it requires an even flow of water over the full width of the channel.

It is not, to my knowledge, something that that Titan of the terroire, Capability Brown, ever tried, though he did leave in place the great cascade at Chatsworth, described by Edward Knight: ‘Water-house & cascade down strait steps 150 yd’ and by Anna Seward: ` ….Chatsworth is my native soil – the first scene of rural grandeur that met my infant eyes. It is only five miles distant from the village in which we lived during my childhood … I soon discerned capabilities in the magnificent situation of which the possessor had not, nor has yet, availed himself; and I exult that the genius of the groves resigns his wand to your guidance. That forced and formal cascade, in which the sullen waters take their measured leaps, always offended me. If the penurious Naiad suffers not their descent to be more than temporary, surely they might yet be allowed to strike the eye with transient sublimity, and road adown the mountain over craggy fragments, and flash through intercepting bushes.’
