GEOMETRICAL FLOWER-GARDENS. 



must be taken that as much water may 

 pass through the oval hole of this cock 

 as passes through the circular hole of the 

 pipe. In conduit-pipes, all elbows, ben cl- 

 ings, and right angles should be avoided 

 as much as possible, since they diminish 

 the force of the water. In long conduit- 

 pipes, air-holes, formed by soldering on 

 upright pieces of pipe, terminating in in- 

 verted valves or suckers, should be made 

 at convenient distances, and protected by 

 shafts built of stone or brick, and covered 

 with movable gratings, in order to let out 

 the air. Where pipes ascend and descend 

 on very uneven surfaces, the strain on the 

 lowest part of the pipe is always the great- 

 est, unless care is taken to relieve this by 

 the judicious disposition of cocks and air- 

 holes. Without this precaution, pipes 

 conducted over irregular surfaces will not 

 last nearly so long as those conducted 

 over a level." 



In fig. 850 we have an excellent speci- 

 men of Parisian casting in iron, a material 

 of all others the best adapted for the pur- 

 pose here exhibited, as being more dur- 

 able, and less liable to accidents, than 

 stone, however good its quality may be. 

 The fountain here shown is from the 

 establishment of M. Ducel of Paris. We

have been unable to ascertain whether he 

 was the designer as well as executor of 

 this subject, which we consider both 

 novel and unique, never having met with 

 anything like a similar design before. 

 This subject might be cast upon the lar- 

 gest scale admissible into a flower-garden 

 of the largest size, or it might be placed 

 in the centre or at the termination of a 

 terrace, whether in immediate connection 

 with buildings or not. 



As a fountain adapted to a flower-garden 

 of the largest size, as possessing far more 

 than ordinary merits as a work of art, 

 apart from the strict rules of architectural 

 design, we cannot present our readers 

 with a more elegant and appropriate 

 specimen than that executed recently for 

 E. L. Betts, Esq. of Preston Hall, de- 

 signed and erected by Mr Thomas, of 

 London, whose talent and taste in works 

 of art have been brought out so completely 

 under Charles Barry, Esq., in modelling 

 the ornamental details of the new palace 

 of Westminster, and elsewhere. The 

 subject of the fountain by this accom- 

 plished artist, and which we have chosen 

 for our illustration, fig. 851, is " Acis and 

 Galatea," surrounded by Tritons. Such 

 a fountain, we should remark, requires 

 851.
