PRACTICE OF GARDENING. 



Part III. 



rivers and rills will readily suggest themselves. Cascades and waterfalls may sometimes 

 be created ; and the occasional expansion of natural brooks into pools, affords a fine hint 

 for imitation, when this form of water comes within a scene of improvement. One of the 

 greatest improvements that can be made in many places laid out in Brown's time, and 

 subsequently, consists in widening in some places, and varying the margin in others, of 

 those tame serpentining canals, then so much in fashion. By this means, and by adding 

 islands and trees, they may often, without deranging the place as to other details, be 

 rendered highly beautiful at a moderate expense, {fig' 699.) 



7225. A waterfall, or cascade, is an obvious improvement where a running stream 

 passes through a demesne (fig. 700.), and is to be formed by first constructing a bank of 

 masonry, presenting an inclined 



700 



plane (a) to the current, and ren- 

 dering it impervious to water by 

 puddling( 1 720. ) or the use of proper 

 cements, and next varying the 

 ridge (6) and under side (c), with 

 fragments of rock, so chosen and 

 placed, as not to present a charac- 

 ter foreign to what nature may 

 be supposed to have produced there. 

 The adjoining ground generally requires to be raised at such scenes, but may generally 

 be harmonised by plantation. 



7226. Where running water is conducted informs belonging to the geometric style of gar- 

 dening, waterfalls and cascades 



are constructed in the form of 

 crescents, flights of steps, or 

 wavy slopes ; all which have ex- 

 cellent effects of their kind when 

 appropriately introduced, as at 

 Chatsworth, Hatton, and many 

 other places. 



7227. A natural stream may 

 sometimes be improved by altering 

 its direction, and bringing it 

 through a more interesting part 

 of the grounds ; and we have 

 known an admirable effect pro- 

 duced by bringing a distant 

 river close to the house, even so 

 much so as to wash the base of its terrace-wall. (Jig. 701.)
