Oakbrook Cottage. - Aug. 3. This is a handsome Gothic cottage, with a tiled roof; the stable and other offices belonging to it having thatched roofs: the whole displaying considerable taste, and being very neatly finished. Taken altogether, it is the very handsomest thing of the kind between London and Brentford. Though the surface on every side is naturally flat for a considerable distance, yet, the buildings being placed on a highly raised platform, the gardens and grounds slope on every side. The garden is carefully planted, and displays a considerable number of the new flowers and shrubs. In passing through Brentford, there is a house on the left which deserves notice for its beautiful lawn, sloping from the street to the Thames. It is so closely shaven, and altogether so highly kept, that we observed, on one occasion, a maidservant on her knees, cleaning the turf with a hand-brush.
