u!erable improvements having been made on this in- 

 strument at Edinburgh, a few words additional concern, 

 ing it, may be excused. The engine consists of a force 

 pump or barrel, commonly two inches and a quarter in 

 diameter, to the bottom of which, above the valve, is 

 connected an air-vessel : into this the water is forced ; 

 and it M emitted from it, by the action of the com- 

 pressed air, throui.li the directing pipe in a continued 

 stream. This pipe is attached to the top of the air- 

 vessel by means of swan-neck swivel joint, with 

 double screw*, which are water tight : in this way the 

 pipe can be moved in any direction. Formerly, leathern 

 valves and a leathern flexible director-pipe were in 

 use ; but from occasional exposure to drought, the seams 

 of the leather were very apt to oj>en, and allow water 

 to escape ; well executed brass work, on the other hand, 

 i of all others least liable to derangement. The pump 

 and air-vessel are Gxed in a capper cistern, sixteen 

 inches deep, and capable of containing about twenty-two 



gallons of water, wine measure. The cistern has like- Implements 

 wise a strong wooden bottom, to which are attached two 

 rollers, an improvement of Mr John Hay's, which greatly 

 facilitate the moving of it when taken into hot-houses or 

 vineries. The engine is, at the same time, fitted to a 

 barrow with wheels, for the conveniency of wheeling 

 it through the garden ; and to this the rollers form no 

 obstacle, as they pass between the slerls of the barrow. 

 The pump is worked by a lever, and requires very little 

 exertion. The water can be projected about fifty feet ; 

 so that wall-trees of any height may be wu-hed, while 

 the engine remains on the gravel walk. 



The best writers on the various branches of horticul- 

 ture, particularly British authors, have been mentioned 

 either in the introduction to this article, or in the course 

 of treating the different parts of the subject ; but it 

 may be useful to recapitulate them here, in alphabeti- 

 cal order. ( i'. v.)
