No. 7. Tarrant Motors Proprietary Limited. Fordson Tractor. 

 B.H.P,, 22. Revolutions per minute, 1,000. Working speed, 3^ 

 miles per hour. Pulled 4-furrow T. Robinson and Company set disc 

 plough, each furrow cutting 7 inches to a depth of 4 inches. The plough- 

 ing with this tractor should have been reduced to 2^ miles per hour, as 

 the discs scattered the soil rather much, leaving large furrows. The 

 mould-board, however, would have done the work at this speed much 

 more efficiently. The fuel used was low-grade kerosene with benzine to 

 start. 



No. 8. Pacific Commercial Company's Cletrac Tractor. B.H.P., 20. 

 Revolutions per minute, 1,200. Working speed, 3 to 3^ miles per hour. 

 This tractor pulled 3-furrow mould-board Mitchell ploughs, each furrow 

 cutting 8 inches to a depth of 4 inches. The fuel used was low-grade 

 kerosene with benzine to start. 



'No. 9. G. V. Davis' Samson Tractor. B.H.P., 24. Revolutions 

 per minute, 1,000. Working speed, 3 miles per hour. It pulled 

 one 4-furrow McKay disc plough. Fuel was low-grade kerosene with 

 benzine to start. This tractor was at work on the second day only of the 

 trials. 



Note on the Ploughing. 



It was apparent to all that the disc ploughs were the lightest of 

 draft under the conditions, but that the mould-boards in most cases did 

 the best work. 



NOTES ON EXPERIMENTAL PLOTS, STATE RESEARCH 

 FARM, WERRIBEE, NOVEMBER, 1919. 



By G. S. Gordon, Field Officer, State Research Farm. 



Crops Generally. 



During the greater portion of the month the Weather has been com- 

 paratively mild, cool, and pleasant, with an absence of the high winds 

 often experienced at Werribee. This, despite the continued light rain- 

 fall, is enabling the crops to mature gradually and the grain to fill better 

 than would have been the case had hot and dry windy conditions fol- 

 lowed the unfavorable growing period mentioned in these notes during 

 the past few months. 



Permanent Rotation Field. 



The hay plots in this field have been harvested and the produce 

 weighed. The yields illustrate the advantages derived from fallowing 

 and crop rotation; but the table below, giving the total and average
