Waterworks. — .These have now been tried, and found to 

 work well. Some jets have been placed in the small basins 

 between the canals, for the purpose of enlivening this part 

 of tho garden. The cascades, without startling or over- 

 powering one by their magnitude and grandeur, like the Grandes 

 Eaux at Versailles, Potsdam, or the Crystal Palace, pour out in a 

 continuous stream a sheet of water 40 feet in breadth, and about 

 JJ-| inches deep, the sparkling clearness of which, combined with 

 the pleasant sight and sound of falling water, will make the 

 vicinity of the large cascade a favoured resting-place of the 

 Fellows in the hot days of summer, as the conservatory already 

 is in the cold days of winter. . 

 - The mode in which the water is worked is this: — It is 



h 



pumped up from the Artesian well by the small engine in the 

 back part of the Conservatory, which draws about 100 gallons 

 in a minute, and poured into tbe system of pipes or arteries 

 by which all the basins and canals are connected together. 



When 



One 



condition of its doing its duty is that these pipes and canals are 

 full of water, as it has to set it in circulation, and, of course, 



unless 



. The principle of circulation is similar to tliat in our own bodies. 

 One great aorta leads down to the reservoir, on the base of the 

 memorial of the Exhibition of 1851, on each side of which there 

 is a broad low arch, within which the water pours' from the 

 reservoir, forming four falls, one facing each quarter of 

 the compass, North, East, West, and South. Issuing, thus, 

 in a mysterious way, under and within the archway, it is re- 

 ceived by a basin which communicates with all these falls, and 

 conducts the water to the front, where it pours itself in a fine 

 sheet into a second large cup or basin, over the lip of which 

 it falls in a still larger sheet into the great basin itself. The 

 water in it flows over into pipes on each side, which may be 

 likened to" the arteries leading to the limbs in the body, and 

 -which lead to the small basins between the canals. After 

 receiving an addition there from the jets (which are worked sepa- 

 rately and independently by the small engine), it overflows 

 into a reservoir behind each basin, from which it again flows
