    process in use in Southern Italy and Sicily. The rinds arc soaked from fifteen to twenty-five minutes in water, to which sometimes a little soda is added. They are taken up singly in the right hand and the outer surface of each is firmly pressed against a large and mther hard-grained sponge held in the left hand and secured by a strap. Two or three sharp turns of the wrist im- part what may be called a screw-pressure to the rind, thus effectually fracturing the oil cells, the sponge ab- sorbing the contents. The sponge is constantly held over an earthen jar and occasionally squeezed into it. The fluid in the jar quickly separates into three different products—the dregs or deposit of mucilaginous and cellular matter, some fruit juice, and the pure oil, which floats on the top. The latter, when bright and clear, is passed, by means of a small glass siphon, into the cans of thin co})per, in which, after sealing, it is stored away for export. The above described primitive mode of fabrication furnishes the most highly prized oils of commerce ; they are called hand-pressed oils or essences preparees a Veponge. In the same manner are obtained the oils from the sweet and bitter pomegranate, the bergamotte, and mandarin orange. Another method of expressing the oil is that of the ecuelle a piquer, much used in the region about Nice. The oils obtained by this method, which are also of a very fine quality, are marked essence a recuelle or au zeste. The apparatus consists of a round shallow pan of copper or brass, having a receptacle for the oil at its lowest part and a lip on one side for pouring, and studded on its concavity by strong blunt spikes.
