Produce
c23.s5.t7.1
The produce of the ore of *Tendukaira* varied from 36 to 40 per cent—but as it was upon the whole nearer to 40 than 36—I am quite safe in fixing the average at 38 per cent; I tried by roasting the ore to obtain a greater quantity but without effect, neither was I satisfied with its result in another point of view, as will be shown hereafter; with regard to charcoal the consumption varied according to its quality—or, in accordance with the working of the furnace. The following diary contains a statement of the daily produce of four smelting furnaces, from which I assumed a mean, as a fair proof of their power of production. They were under my own superintendence from the 30th April to 6th June 1827 which is beyond all question the most unfavourable portion of the year for smelting iron, and the result therefore is the more enhanced in value.

From this statement it appears that each furnace yielded upon an average about 18½ *Panchseri*,⁷ and that every hundred sers of crude metal yielded 63 sers of malleable iron; the total of the produce therefore is as follows: the ore yielded 38 per

⁷ *Panchseri* is a weight of 5 sers.
