teurs who find pleasure in taking a share in 

 the work of their gardens. One of the special 



features of this machine is its extreme simplicity, 

 as it is composed of the smallest number of 

 pieces of any machine extant. In the figure 

 the grass -box is shown detached, but it fits on 

 to the front of the machine in the same way as 

 that represented at fig. 219. There are numer- 

 ous other forms of lawn-mowers in the market, 

 most of which differ only from those here 

 described in some non - essential detail. In 

 this respect they may be compared with the 

 bicycle. Some of them may have, as claimed 

 by their makers, superior points, such as the 

 number of cutters, the presence 

 or absence of grass-boxes, cov- 

 ered gearing, front rollers, mov- 

 able plates, &c. 



The Lawn-mower Carriage 

 (fig. 221) has been designed for 

 conveying lawn-mowers from 

 place to place, so as to avoid run- 

 ning them over gravel or rough 

 ground, which is apt to damage 

 the knives and gearing. The 

 machine has only to be raised at 

 the handles and the carriage 

 pushed under it so that the part

of the machine in front of the rollers may rest 

 on the wood cushion of the carriage. The 

 machine is then lowered on to the carriage, and 

 may be wheeled about with the greatest ease.

Hose-pipes (fig. 223). — A good supply of hose- 

 pipes should form part of the equipment of 

 every garden, the health of many plants being 

 jeopardized in dry weather when watering is 

 difficult. Water should be laid on wherever it 

 is likely to be required, and either hydrants or 

 stand-cocks placed at convenient intervals in all
