WEATHER FORECASTING. 65 



the clear sky after sunset, that is the direction from which to 

 expect the wind to blow. 



Cirrus clouds move from a westerly direction over the 

 Peninsula ; if they back to the north-west look for a depression, 

 if they veer to the S.W. or S.. a high is approaching or a black 

 S.E. " low " between Cape Town and Clanwilliam may be 

 forming. 



When E. or S.E. winds blow over the Eastern Province, 

 a depression is approaching from the south-west, then forecast 

 rain when they go to the W. or S.W. 



The foregoing embodies some of the general principles of 

 weather forecasting in the Cape Province ; the writer is not 

 conversant with the conditions governing the weather changes 

 over the Transvaal or the Upper Plateau ; it is hoped that in 

 time observing stations will be inaugurated upon the latter and 

 that our knowledge of the weather progression will embrace the 

 whole of South Africa from the Zambesi to Cape Point. 



Resources and Industries of the Cape 

 PROVINCE. — On page 356 of the last volume the publication of 

 Mr. Somerset Playne's work on the History, Commerce, Indus- 

 tries and Resources of the Cape Colony was noted. So hand- 

 some and profusely illustrated a book, however, calls for a more 

 extended reference. It is the outcome of personal visits to 

 numerous farms in the area dealt with, and includes over 2,000 

 photographs and descriptions of many of the most important 

 farms in the country, together with specially written descriptive 

 articles on such subjects as cattle, ostriches, tobacco, viticulture, 

 the Native races of the Province, its fauna, flora, meteorology, 

 and varied aspects of colonial life, activity and progress, all 

 arranged in a manner such as to render the whole compilation 

 not only valuable for reference purposes, but also greatly interest . 

 ing to everyone who occupies himself either in aiding or watching 

 the advancement of the Province and of the Union as a whole. 

 The contributors include such well-known names as those of 

 Messrs. Oscar Evans, P. R. Malleson, Prof. P. D. Hahn, C. G. 

 Lee, W. C. Scully, and the Librarian of the Royal Colonial 

 Institute, the last-named contributing an article on the literature 

 relating to the Cape Province. 



AIRCRAFT. — In a work on " Monoplanes and Biplanes ; 

 their Design, Construction, and Operation," which is published 

 by Sampson Low, Marston & Co., Mr. G. C. Loening, B.Sc, dis- 

 cusses, among many other phases of aircraft, the view that many 

 of the accidents which befall airmen are avoidable, a view which 

 he strongly defends, notwithstanding the many fatalities that are 

 constantly occurring. The firm just mentioned also publish a 

 work on " All the World's Airships," by Fred. T. Jane, who has 

 become well known in connection with the annual publication of 

 '* The Fighting Ships of the World/'
