Tiglium}), which furnishes a powerful purgative oil. Of wild
or uncultivated oils, the most commonly used are Kekuna
(Aleurites Triloba) and Domba (Calophylivm inophylivm),
chiefly as illuminants, but also valued medicinally. Mi
oil (Bassia longifolia) is of a heavy consistency inclining
to solidity and used for burning. Samples of Kekuna and
Mi sent to England have been well thought of for soapmaking
 and other purposes. Kohomba or margosa (4dzadirachia
 indica) is the name of a disagreeably smelling heavy
oil, which, however, possesses most valuable antiseptic
properties, Cashew or caju oil (Anacardium occidentale) is
of two kinds : the one from the kernel is sweet and bland,
that got from the shell is acrid and acts as a powerful
vesicant. The wood oil obtained from the Dorana tree
(Dipterocarpus glandulosus) is resinous and useful for
making varnishes. The Kina (Calophylium tomentosum)
and Mihiriya (Palaguiwm petiolare) yield. oils of minor
importance : the former is used for burning and also medieinally;
 the latter, which is of a semi-solid consistency, for
medicine and food. Still another oil used, but only to a
small extent, for burning is that obtained from Kon (Schleishera
 trijuga), also known as the Ceylon oak. The grass
yielding lemon grass oil, got from Andropogon Citiratus,
is cultivated to a limited extent. It belongs to the class of
sggential oils. A sampleisshown by Messrs. Winter &amp; Sons.
“Besides the commercial fibres obtained from the cocoanut,
 kitul, and palmyra palms, the Island is particularly rich
in fibres yielded by uncultivated plants. These are of the
greatest use to the villager in his every-day life, though not
produced in sufficient quantity for export. The more important
 wild fibres are Niyanda (Sanseviera zeylanica), used in
the manufacture of Kandyan mats, whips, &amp;ec., and Hana
(Crotalaria junced), for fishing nets; but the following list
includes the names of many that serve the people well and
are worth looking into :—XKala (Derris scandens), Gas-netul
