solidarity of aim. Several problems have arisen and have been dealt 

 with in a satisfactory and uniform manner, that previously would 

 either have been disposed of as tlie individual institution first 

 confronted therewith thought fit, or left in abeyance until a chemists' 

 conference could consider it. 



With the important matter of the agricultural soil survey of the 

 Union little progress has been made. It is impossible for the Chief 

 of the Division to give the survey the undivided attention which is 

 essential, and Mr. Stead, Senior Chemist oi the Division, who was 

 placed in charge thereof, was prevented by other duties and prolonged 

 illness from assuming that charge. The work will, it is coniidently 

 hoped, sjon be commenced. 



2. Comuiission Work. — During the year the Chief of the Division 

 served on committees appointed to investigate the problems arising 

 from the need of cheap industrial iilcohol, and to iiKjuire into the 

 matter of the destruction of prickly-pear. 



From October, 1920, until well into thp year under report, Mr. 

 Stead was virtually seconded for service as a member of the Drought 

 Commission. The first-hand knowledge of the country and its 

 problems and conditions gained in the course of this inquiry should 

 prove of great value to the ])i\-isioii.

 were publislied during the twelve months: —
