THE PHOSPHATE CONTENT OF CANE JUICE
The results immediately show the large fluctuations that can occur in the phosphate content of the crusher liquor at a given mill. The method consists essentially of precipitating the phosphate as phospho-molybdate in the boiled and filtered liquor. The average result5 mdIcts an increase in the total phosphate content of the juice from the fertilized sections over the controls from 51 to 91 per ce'!lt.

This steeply sloping land surface has been heavily eroded by numerous rivers, so we note that the majority of cultivated land is in expansion. high altitude above the riverbeds, a circumstance which has a very serious effect on the problem of obtaining water on land. 1 is appended with the names of the principal streams beginning in the south and pro.

EFFECT OF IRRIGATION ON SUGAR CANE
When estimating the production of sugar from cane, a good average figure of 10 tons of sugar cane per tons of sugar. He can get a general idea of the permissible rape expenses in the case of a gravity scheme from the consideration below. From empirical data I have found that the operating costs of the plant are given by £O.
Assuming that, due to the disturbed nature of the soil, an average production of JOO tons of sugar per plant occurs. Due to the steep slopes and narrow rivers of the Natal Rivers, these will generally be the case. A reasonable capital investment in gravity systems would yield £60.09 per tonne of additional sugar produced by irrigation, or £300 per It is possible that with the use of large devices and especially if the electricity is obtained at a low cmst per unit, the height limit can be increased as noted above. The total annual cost of such storage shall not exceed £2 per hectare net shoe. With crude oil pumping facilities allowing for the same limitation on '\Vater Supply Costs, we find that the payable lift would be about 133 feet. With an increased yield of I t on of :-weeks per acre the initial charge is therefore £3 per acre. tons of sugar. In order to effectively spread the water over the ground, it is most important, as cane is a shallow root plant, and therefore the water quickly seeps down under the roots. However, to determine this, careful experiments are required to find out how L'ba Cane responds to the application of ",'ater in different months of the year. CONCLUSION SWAZ/LANO BURNT CANE Solids, on the other hand, are far more difficult to handle, and this difficulty increases with the size of the pieces that make up the main mass. One method is to throw a wide-mesh rope net over the top of the truck and remove some fTOm under each knot. When inserted, the openings of the t\yO parts collapse and the inner tube is filled.
