Although closely acquainted with every nook about Rydal Park, I have never been able to discover any spot corresponding to that described in Wordsworth's lines to M. H. It is possible, however, that the 'small bed of water' may have been a temporary rain pool, such as sometimes lodges in the hollows on the mountain-slope after heavy rain.

I do not know of any pool of water in the Upper Rydal Park. There are some pools up the river, 'Mirror Pool' among them; but I hardly think there can ever have been 'beech-trees' growing near them.
