then red-brown clay, after that yellowish-green clay ; at one puruṣa lies a
stone ;—there certainly is water underneath.”
65-66. “Should the anthill stand on the eastern side of the Pīlu tree
then it may be predicted that in a southerly direction there is water at
7 puruṣas at a distance of 4 cubits and a half. (The signs are :) at one
puruṣa a snake, half white, half black, one cubit long. A vein from the
south there supplies plenty of brackish water.’
67. “From a snake’s abode standing to the north of a Karīra tree one
may infer that there is sweet water south-ward at 10 puruṣas, the sign
being a yellow frog at one puruṣa.”
68. “If to the west of an Andersonia tree there is an abode of snakes, you
will find, at 3 cubits more to the south after digging 12 puruṣas a western
vein of brackish water.”
69. “An anthill being visible to the east of an Arjuna tree indicates that
you will come at a vein at a cubit's distance to the west by digging 14 puruṣas.
(An indication is)—a great brown lizard at one puruṣa.”
70-71. “Or, if there be a snake's abode to the left (i. e. north) of
any tree denominated after gold, there is water 2 cubits from thence in
the southern direction at 15 puruṣas. The water is brackish. (The signs
under the surface are) : an ichneumon (nakula) at half a puruṣa, and a
copper-coloured stone along with red earth. The vein is one issuing from
the south.”
72-73. “Where a jujube tree and an Andersonia stand conjoined
even without an anthill, there is water 3 cubits further to the west at
16 puruṣas. (Below the surface will be discovered)—first water of good
taste, produced by a southern vein, then a northern vein ; at half a puruṣa
a leaden-hued stone, white clay and a scorpion.”
74. “Should a jujube tree appear conjointly with a Karīra there will be
water in the west, 3 cubits off at 18 puruṣas. It is a north-eastern vein
rich in water.”
75. “On the east side of a jujube combined with a Pīlu water will be
found never drying, but brackish, at 20 puruṣas.”
76. “Where an Arjuna stands conjointly with a Karīra, or with a Bilva,
water will be found 2 cubits further off in the west at 25 puruṣas.”.
77. “Should it happen that bent grass or sacrificial grass on the top of an
anthill appear of a pale yellow colour, then sink a well in the middle thereof,
for there is water at 21 puruṣas.”
78. “Where bent grass is seen growing on an anthill near a Kadamba
tree, there is water 3 cubits further off, to the south at 25 puruṣas.”
79-80. “If an Andersonia conjointly with 3 other trees of various kinds
is seen in the midst of 3 anthills, there will be water to the north, at an
