absence of all ignition devices, and the power of self-starting 

 at any time at a moment's notice. But there is much to be 

 done in the way of simplification, &c., before a machine is 

 produced with these advantages, and at the same time suitable 

 for the trying conditions under which an agricultural motor 

 has commonlj^ to work ; but with the able brains now at work on 

 the subject, there is little doubt that we may confidently look 

 forward to very interesting developments at the Shows of the 

 R.A.S.E. in the next few years. 



An interesting example is that shown as a New Implement 

 by Messrs. Fetters, Ltd., Nautilus Works, Yeovil. Exhibit 

 No. 193. This engine has been designed with the idea of

combining the merits of the high compression Diesel engine 

 with those of the ordinary low compression oil engine. It is 

 claimed that the engine works as well with crude oil as with 

 refined petroleum. It is also claimed that the working cost is 

 very low. In starting the engine, the vaporiser is heated by 

 a lamp which is extinguished after the engine is started. At 

 the end of the firing stroke the exhaust ports are uncovered, 

 and the products of combustion expelled by pure air that has 

 been previously compressed in the crank chamber. The fuel 

 is pumped into the vaporiser under pressure, at the end of the 

 compression stroke, the firing taking place automatically. The
