Dr. J. R. Sutton. A brief account was giv'en of some points of interest 

 in the results of temperature observations by Harbor at Mochudi in the 

 Bechuanaland Protectorate. The extremes of temperature are consider- 

 ' able, the greatest range so far observed' l)eing from 108° F. to 28° F. 

 The mean maximum temperatures depend upon the sun's meridian altitude 

 in miuch the same way as as they do at Kimberley. The annual cold wave 

 of the middle of July is felt at Mochudi as it is elsewhere further South. 



South African Institute of Engineers. — Thursday, April i6th : Mr. 

 W. Calder, President, in the chair. — " Irrigation, with special reference to 

 the future of Engineering work in South Africa " : F. K. Stevens. The 

 author broadly sketched the irrigation methods adopted in the United 

 States. Canada, Australia, India and Egypt, and then compared the various 

 systems of applying the water to the lands. He indicated the sources of 

 water supply in South Africa (i) from perennial streams: (2) from 

 rivers subject to large fluctuations; and (3) from rivers subject to occa- 

 sional flow, and, with special reference to South Africa, discussed the 

 subjects of rainfall and run-off, pumping, and pumping appliances, some 

 of the financial aspects of irrigation, the opportunities for engineering 

 work in connection with irrigation, and finally gave some details with 

 regard to a number of South African irrigation schemes, in existence and 

 projected.
