is on the simple ball-valve principle, so that this barrow-engine 

 is not only a machine of great power, but not liable to get out of repair. 

 The hydronette is an instrument recently invented, which is very 

 useful in syringing in glass-houses. 



Water-carts or barrows (see illus- 

 tration) are likewise much used 

 in gardens for the conveyance of 

 water on a large scale; gutta-percha 

 tubing and other piping are, however, 

 being rapidly substituted for these, 

 and are of the highest value as labour- 

 saving expedients. Nevertheless, there 

 E. are few gardens where a number of 

 two-wheeled hand water-carts are not 

 ^T^ necessary, and it is of great moment to 

 the full enjoyment of a garden in dry 

 weather that some of them should be 

 furnished with spreaders for the watering of gravel walks, roads, &c. 



When a large house is to be fumigated with tobacco or other smoke, 

 a fumigating pot, such as fig. 86, may be used. It is made of sheet- 

 iron, holds about three pounds of 

 tobacco, and is placed on the out- 

 side of the house, with the smoke- 

 tube entering it through a hole 

 made on purpose in the front wall 

 or front glass. In the figure a is 

 the handle by which the pot is 

 carried, b the pipe by which this 

 smoke is introduced to the house, 

 and which is attached to a move- 

 able lid, and c, a tube to which 

 the bellows is applied, and which 

 enters the pot immediately under 

 a perforated moveable bottom. A substitute for a pot of this kind is 

 often formed by two flower-pots, a smaller one being placed upside 

 down within a larger, and the tobacco placed in the former. Messrs. 



Dean and Appleby have re- 

 cently invented a very 

 simple and efficient fumi- 

 gator. In fumigating plant- 

 houses, the air should be 

 as dry as possible, otherwise 

 the aphides conceal them- 

 selves in the globules of

water, and so escape destruction. A pair of common bellows may be 

 rendered fit either for powdering plants or fumigating them, by sub- 

 stituting a piece of tinned iron, fig. 87, a, resembling in shape those 

 tin scales used in the retail of meal, in the flat end of which, #, are 

 two small valves 1J inch in diameter, with a hole between them, to
