the 1918 Report. It was again tried on a sewage farm near 

 Shrewsbury, and its performance did not seem to be much 

 better than that in the previous trial. No alteration seems to 

 have been made in the general design. The price, 850?., 

 would seem to place it beyond the reach of the ordinary 

 agriculturist. 



W. & T. Avery, of Birmingham, showed on Stand 352 an 

 Automatic Fuel Oil Weigher. Although entered as a new 

 implement there is no material departure in design from that 

 of their well-known automatic weighers for grain, &c. There

 use amongst the vines in France. 



The Agricultural Motor on Stand 359, Saunderson & Mills, 

 Bedford, appears to be a thoroughly practical and well-thought- 

 out machine, but of limited capacity, due to its small power ; 

 there is nothing particularly new in the details. 



To the Wyles Motor Plough, Stand 362, Wyles Motor Plough 

 Co., 10 Park Road, Leeds, must be applied the remarks, made 

 in last year's Report, that it is useless to limit the capacity of a
