THE CONVEYANCE OF PRODUCE 143 



Efforts have been made to provide machines that will 

 perform both land and road work and to some extent 

 this has been accomplished. But the best authori- 

 ties agree that so far as development has proceeded up 

 to the present it is more satisfactory to employ different 

 machines for the two purposes. Substantial advance 

 has been made in the improvement of the road motors, 

 etc., and though some of the earlier forms have proved 

 disappointing, yet there are many of the latest types 

 being worked to the entire satisfaction of their owners. 

 The extension has been much greater amongst large 

 manufacturers in town than in the market garden 

 industry, but an increasing attention is being paid to the 

 matter by these producers, most of whom speak favour- 

 ably of their results which have now passed the experi- 

 mental stage. A special issue of the Commercial 

 Motor (Temple Press, London) on August 31st, 1 905, 

 gave an exhaustive description of the progress made by 

 market gardeners in the utilisation of motor power for 

 traction purposes, together with illustrations of the 

 various types of machines already in use. Reference to 

 this journal will give much more information on the 

 subject than our space will permit, but a few of the 

 principal points are worthy of notice.
