stroke, 57 B.H.P. by R.A.C. rating ; and the other 4-cylinder, 

 25 H.P., R.A.C. rating. In both these the well-known sleeve 

 valve engine is used. In the larger tractor the engine is carrieil 

 behind, while in the smaller it is placed in front. In both cases 

 there is a cone clutch, but in the larger size metal to metal is 

 used, while in the smaller the cone is leather covered. The 

 Renard Train, No. 1296 (Daimler Renard System), is, of course,

 structed of steel girders, on castor wheels in front, with 

 platform, each plough being provided with a lever, by which it 

 can be put in, or out, of work independently of the others by 

 the ploughman standing on the platform. Each has a screw 

 adjustment by means of which the shares may be given more 

 pitch, or downward inclination, when the points become worn. 

 The castor wheel which supports each plough, and by which

 depth of ploughing on uneven land. Each share cuts a width 

 of 14 in., and the depths of working can be adjusted from 6 in. 

 to 12 in.
