460 बृहत्संहितायाम् [Adh. LIV. Sl. 7-10.
चिह्नमपि चार्धपुरुषे मण्डूकः पाण्डुरोऽथ मृत् पीता ।
पुटभेदकश्च तस्मिन् पाषाणो भवति तोयमधः ॥७॥
Slokas 6-7.—If rotang (tree) is seen flourishing in
a waterless tract, there will be water at a depth of 7½
cubits at a distance of 3 cubits to the west of the tree.
There will be found a westerly vein flowing underneath.
At a depth of 2½ cubits, the symptoms would be a pale
white frog ; thereafter, yellow clay, and further, a very
hard stone (which will break only by the application of
great heat) and underneath that there will be water.
Man's height is 120 digits or 5 cubits.
जम्ब्वाश्चोदग्घस्तैस्त्रिभिः शिराधो नरद्वये पूर्वा ।
मृल्लोहगन्धिका पाण्डुरा च पुरुषेऽत्र मण्डूकः ॥८॥
Sloka 8.—In a similar tract, if a Jambu tree is found,
an easterly vein will be obtained at a depth of ten cubits
at a distance of three cubits to its north. The signs are,
the earth smelling like iron at a depth of five cubits ;
next, pale-white clay, and further, a frog.
जम्बूवृक्षस्य प्राग्वल्मीको यदि भवेत् समीपस्थः ।
तस्माद्दक्षिणपार्श्वे सलिलं पुरुषद्वये स्वादु ॥९॥
अर्धपुरुषे च मत्स्यः पारावतसन्निभश्च पाषाणः ।
मृद्भवति चात्र नीला दीर्घं कालं च बहु तोयम् ॥१०॥
Slokas 9-10.—If there is an ant-hill nearby to the
east of a Jambu tree, there will be sweet water at a depth
of ten cubits at a distance of three cubits to the south of
the tree. When the earth is dug 2½ cubits deep, there
will be found fish ; next a stone with the colour of a
dove ; and next blue clay. Here there will be plenty of
water for a long time.
