Mr. A. Brunner, Helyana-Landen, near Palembang (Sumatra), reports 
upon the following experiments with fertilisers :— ; 
1. Plants set on 28rd Iebruary, 1894, 10,117 to the acre. Sulphate of 
potash and carbonate of potash-magnesia were applied, in addition to green 
manuring with legumes. ‘The tobacco from the various plots was tested and 
analysed at the Agricultural Experiment Station in Rufach by Prof. Barth, 
and the following result obtained :—

Two hundred and ninety-fonr pounds of carbonate of potash-magnesia 
per acre produced an improvement in the burning quality. The increase of 
this application to 446 Ib. failed to produce a corresponding improvement, nor 
was the quantity of potash absorbed by the plant increased. 
Unfortunately, the absence of a sufficient number of labourers made it 
impossible to gather the yields from the various plots’separately. The total 
yield from 2,471 acres, exclusive of second sprout, was 2,640 1b. of Delideck- 
leaf tobacco, which sold at 5 Fl. per Dutch pound in Rotterdam. 
2, Another experimental field was planted on 25th December, 1894. The 
results of the tests conducted at Rufach were as follows :— °
