Ch. III – Durgādilakṣaṇam 93
63. This machine moves all round by one pillar of the Markaṭī. (In
a Markaṭī one column is moving it everywhere .) The wings will be
on the half part of the rod and the length and breadth will be 1/
3rd each.
64. The Markaṭī will be placed neither on the 1/4th part of the
wings, nor near the rod. A boulder should be hung at the back
for a uniform distribution of the pressure.
65-66. Two wings are to be set up on the pillar for moving the discs. The
height of the Markaṭī will be similar to the scale of the Dhiṅkulī.
The length of the scale will be divided into three segments. The
disc and the two wings are to be placed therein. Among various
arms of superior quality, Gaurīyantra is one such.
67-68. It can easily move everywhere, and it is conducive to easily avail-
able comforts. The carriers of the machines are to be rewarded
with gold ornaments, silks, villages and excellent vehicles for jour-
neys, by the leader of the people.
Thus ends the definition of war machinery.
69. Among the fire arms (Agniyantra) the tubular weapon is used to
throw bricks, wood, spears and stones. It is made of either brass
or bell metal and there is a cardinal point by which one can easily
aim at the target.
70. It should be strong, made of iron, close knitted and ornamented
with a serpent belt (Kaṭaka). It will be like the Dhattūra flower, but
the length will be three to six times.
71. The front part will be twice the base, the base part is half or little
more. Sometimes on the back a cover will be made like the whirls
of a conch.
72. Some mark a small hole there for ignition. According to the
size of the tube, medicament is to be inserted.
73. A piece of wood according to the size of the tube is to be placed
in front of the medicament. Then, in the mouth of the tube,
iron or wooden balls are to be put inside.
