288 SCIENCE OF GARDENING. Part II. 



of these, simplicity ought to be attended to ; for a complicated machine is not only more 

 expensive, and more apt to be out of order, but there is also a greater degree of 

 friction, according to the number of rubbing parts.

1 440. The more cumbrous machines of gardening are the barrow, roller, watering-engine, 

 boat-scythe, ladder engine, and transplanter. 1 99 



1441. Garden-wheelbarrows are of several 

 species. The common garden-wheelbarroiv 

 {fig. 199.) is a box, open at top, placed on 

 two levers, terminating in a wheel and axle 

 at one end, and in two handles at the other. 

 They are commonly made of wood, the levers 



of ash or elm, and the sides and bottom of any soft woodT The wheel is either wholly of 

 cast-iron, or of wood, shod with wrought-iron. Excellent garden- wheelbarrows are now 

 made of wrought-iron ; but wooden ones are better for new ground work. They are used 

 for conveying dung, weeds, garden-soils, litter, &c. 



1442. The separating barrow is, in appearance, the same as the above, buf the body being 

 kept in its place by two iron bolts at opposite angles of the bottom, may be lifted off by 

 two men, and thus tan, dung, and other articles are readily carried into hot-houses, where 

 the wheel and levers could not be pushed along. 



1 443. The new ground work barrow {fig. 200. ) 

 differs from the first in having the sides and 

 back very low, and a front of the same height. 

 It is made much stronger, and is used chiefly for 

 wheeling earth, clay, or gravel, in extensive ex- 

 cavations or removals, of these materials. 



1444. The haulm-barrow (fig. 201.) is an open box 

 or case of wicker or other work placed on or suspended 

 from a pair of handles, with or without a wheel, and is 

 useful for carrying litter, leaves, haulm, spray, prunings 

 of hedges, &c. 



1445. The flower-pot barrow is a flat surface and 

 wheel, on which plants, pots, or leaves are placed either 

 directly, or when small in one or more shallow baskets. 



1446. The ivater-barrow, instead of a box, contains a barrel, tub, or cistern, in 

 fluid manure or mere water is conveyed to different parts of the garden. 



1447. The hand-barrow is a frame of 

 wood carried by two levers, which form four 

 handles, and is used, in gardening, for re- 

 moving large pots or tubs of trees in blossom 

 or in fruit, and which wheeling might shake 

 and otherwise injure. 



1448. Watering-engines are of several 

 species. 



1449. The pump-syringe, or hand forcing- 

 pump (fig. 202. ) consists of a barrel-piston 

 and directing-tube. The water is drawn 

 up through a perforated base ; and the ad- 

 vantage of this engine is, that it may be 

 placed in any common watering-pot or 

 bucket, and thus much room and some 

 trouble and expense saved in small gardens. 



1450. The ban-oiv watering-engine (fig. 

 203.) is a portable forcing-pump so ar- 

 ranged as to throw the water forty or fifty feet 

 distance, and either in the form of a spout or a 

 fine shower. The cistern commonly contains 

 from twenty to thirty gallons of water, and 

 the frame which holds it being fitted up as 

 a wheelbarrow, it may be wheeled round the 

 garden, and the walks, borders, or even the 

 compartments to the extent of forty-five feet 

 from the walk may be watered completely.
