About Seringapatam, as soon as the millet crop has been reaped the field is ploughed four times, and the seed sown, a gallon per acre, during the month of July or August, after the first heavy rain.  No manure or weeding is required, for the crop will grow on the worst soils.  It is reaped in three months, being cut close to the ground, and stacked for a week.  After exposure to the sun for two or three days, the seed is beaten out with a stick.  The crop in Mysore rarely yields two bushels per acre, but about Poonah the produce is much larger.  The seed is sometimes parched and made into sweetmeats, but is usually grown for its oil.  This is used in cooking, but it is not so abundant in the seed, nor so good as that of the sesame.  Bullocks will not eat the stems unless pressed by hunger.

About 5,000 maunds are exported annually from Calcutta. 3,703 bags were imported into Liverpool in 1851.  The price per quarter of eight bushels, in January, 1853, was from 30s. to L2; of teel oil, in tins, weighing 60 to 100 pounds, L2 to L2 4s.

Bombay linseed was worth L2 11s. to L2 12s. the quarter of eight bushels, in January, 1853.  Bengal ditto 2s. less.  The imports into Liverpool were 68,468 bags and 54,834 pockets in 1851, and 14,490 bags and 33,700 pockets in 1852.  About 9,000 bags of mustard seed and from 18,000 to 20,000 bags of rape seed are also imported thence.  The price of the latter is about L2 the quarter.

NATIVE OIL MILLS.—­The principal native oil mill of India, of which, however, there are some varieties, consists of a simple wooden mortar with revolving pestle.  It is in common use in all Belgaum and Bangalore.  Two oxen are harnessed to the geering, which depends from the extremity of the pestle,—­a man sits on the top of the mortar, and throws in the seeds that may have got displaced.  The mill grinds twice a day; a fresh man and team being employed on each occasion.  When sesame oil is to be made, about seventy seers measure, or two and a half bushels of seeds are thrown in; to this ten seers, or two quarts and three-quarters of water, are gradually added; this on the continuance of the grinding, which lasts in all six hours, unites with the fibrous portion of the seeds, and forms a cake, which, when removed, leaves the oil clean and pure at the bottom of the mortar.  From this it is taken out by a coco-nut shell cup, on the pestle being withdrawn.  Other seed oils are described by Dr. Buchanan, as made almost entirely in the same way as the sesamum.  The exceptions are the hamlu, or castor oil, obtained from either the small or large varieties of Ricinus.  This, at Seringapatam, is first parched in pots, containing something more than a seer each.  It is then beaten in a mortar, and formed into balls; of these from four to sixteen seers are put in an earthenware pot and boiled with an equal quantity of water, for the space of five hours; frequent care being taken to stir the mixture to prevent it from burning.  The oil now floats on the surface, and is skimmed off pure.  The oil mill made use of at Bombay, and to the northward, at Surat, Cambay, Kurrachee, &c., differs a little from that just described, in having a very strong wooden frame round the mouth of the mortar; on this the man who keeps the seeds in order sits.  In Scinde a camel is employed to drive the mill instead of bullocks.
