Slokas 79-80.—When there is a Rohitaka tree sur-
rounded by three trees of different types in the midst of
three ant-hills, water is to be predicted there. The
water is four cubits and 16 digits to the north of the
centre of the ant-hills at a depth of 200 cubits. First
a stone will be seen and beneath that a water-vein.

पश्चात् पञ्चकरान्ते शतार्धसंख्यैर्नरैः सलिलम् ॥८१॥
Sloka 81.—Where there is a knotty Samee tree and
an ant-hill to its north, there is water 5 cubits to the
west at a depth of 250 cubits.

तस्मिन् शिरा प्रदिष्टा नरषष्ट्या पञ्चवर्जितया ॥८२॥
Sloka 82.—When there are five ant-hills in a place
and the central one is white, there is a vein underneath
the middle one at a depth of 275 cubits.

Sloka 83.—Where a Samee tree is combined with
a Palasa, there is water 5 cubits to its west at a depth of

gravel.
वल्मीकेन परिवृतः श्वेतो रोहीतको भवेद्यस्मिन् ।
पूर्वेण हस्तमात्रे सप्तत्या मानवैरम्बु ॥८४॥
