Covered garden corridor pergola

We read of the hanging gardens of Babylon, and I have heard described (by an eye-witness) something similar in the gardens still existing near Damascus.* Of all the comforts belonging to a garden, there is none more delightful than the covered way, or rustic corridor of Woburn: such a line of communication naturally suggests itself here, from the cottage, to the conservatory, and from thence to the forcing-houses, terrace-garden, &c. *[From these hints, I will confess, that, in two other situations, I have recommended a similar disposal of garden in terraces: but, with this difference,-at Beaudesert (Marquis of Anglesea's), the shape of the ground requires the walls to be straight; at Sherringham Bower (Mr. Upcher's), the walls were proposed convex, and the ground behind the cottage at Endsleigh requires the walls to be concave: thus, the same expedient may be varied, to suit various situations, but all contributing to the comfort of habitation.]
