 [Excerpts of pamphlets issued by The Chilean Nitrate Propaganda and Hawaiian Sugar 

 Planters' Assoc. Exp. Sta.] — Sugar cane is being successfully grown in Natal throughout 

 the country extending from Port Shepstone on the South Coast to the Umfolosi River on the 

 North Coast. The average mean temperature of this region is 77°F., the average annual 

 rainfall about 40 inches. The Uba cane (Saccharum officinale) has been known to root to a 

 depth of 12 feet. This deep-rooting habit enables the cane to withstand high winds and the 

 recurring periods of drouth which are sometimes destructive to the shallow rooting varieties. 

 Uba cane although introduced into Mauritius from Brazil in 1869 probably originated in India. 

 Analysis of Uba cane shows a large percentage of fibre but a good quality of juice, the aver- 

 age and maximum being as follows in each case: Total solids in juice, 20.32 and 22.70 per cent; 

 Sucrose, 18.61 and 20.79 per cent; Purity, 91.60 and 91.20 per cent.— H. N. Vinall.

 1919.— A compilation showing the remarkable expansion in the uses of the soy bean (Soja 

 max), especially as a human food. Figures are given for the exports of soy beans and soy- 

 bean products from Manchuria. In 1907 the annual exports did not exceed 120,000 tons, 

 while in 1909 they had increased to 700,000 or 800,000 tons and the British consul at New- 

 chang estimated the export of the bean in all its forms from that port in 1909 as 1,300,000 tons. 

 The various uses of the soy bean in commerce are listed. — H. N. Vinall.
