nitrogen, and superphosphate of lime. About ten per cent of the amount of fertilizer required for the crop is applied at the time of fitting the ground, the balance being administered from time to time as the season advances. Two crops of the rush may be taken from the same ground each year or it is grown in rotation with rice, but most extensively on the lands less readily drained and not so well suited for other crops. Fields of the rush, growing in alternation with rice, are seen in Fig. 45, and in Fig. 227, with the Government salt fields lying along the seashore beyond.

Fig. 227.—Fields of matting rush with recently transplanted rice, and Government salt fields in the background.
With the most vigorous growth the rush attain a hight
exceeding three feet and the market price varies materially
with the length of the stems. Good yields, under the best
culture, may be as high as 6.5 tons per acre of the dry
stems but the average yield is less, that of 1905 being 8531
