An unity of design in all compositions is, confessedly, one of the first principles in each of the polite arts; and nothing, perhaps, evinces more strongly the love of unity acting on the mind in landscape gardening, than the following fact,-viz., that the most superficial observer of any park scene will be displeased by the view of two separate pieces of water; and he will probably ask, without reflecting on the difference of levels, why they are not formed into one? The first opinion seems, therefore, that these two waters should be united: but if the union is not clearly possible, it certainly ought not to be attempted. The second opinion is, that the upper pool ought to be destroyed; or, as some express themselves, should be filled up: but the latter would be an Herculean labour to very little purpose; and the former, though practicable, would not be advisable, because so deep a hollow immediately in front of the house, would be a yawning chasm, very difficult to convert into an object of beauty. My opinion, therefore, is, that the two waters should, from the house, appear to be connected with each other, although in reality they are very far asunder; and the means of effecting such a deception will require some theoretical reasoning to explain.
