The boughs bore leaves of green, that for want of sunshine had faded into almost lily-white; and from the underside of this natural sylvan bridge depended long and beautiful tresses of ivy, which waved gently in the breeze, that might, poetically speaking, be called the breath of the waterfall.

This provision secures the covering of the cross girders on their undersides by the ceiling slabs.

It is then carefully turned over, so as to expose the underside to the direct action of the sun.
