Adh. LIV. Sl. 11-15.] चतुःपञ्चाशोऽध्यायः 461 पश्चादुदुम्बरस्य त्रिभिरेव करैर्नरद्वये सार्धे । पुरुषे सितोऽहिरश्माञ्जनोपमोऽधः शिरा सुजला ॥११॥ Sloka 11.—If there is an Indian Fig tree in a water- less tract (with or without an ant-hill thereby), there will be a vein of good water at a distance of only three cubits to its west and at a depth of 12½ cubits. Here, the signs are a white snake at a depth of five cubits and further a stone as dark as collyrium. उदगर्जुनस्य दृश्यो वल्मीको यदि ततोऽर्जुनाद्धस्तैः । त्रिभिरम्बु भवति पुरुषैस्त्रिभिरर्धसमन्वितैः पश्चात् ॥१२॥ श्वेता गोधार्धनरे पुरुषे मृद्धूसरा ततः कृष्णा । पीता सिता ससिकता ततो जलं निर्दिशेदमितम् ॥१३॥ Slokas 12-13. - If there be an ant-hill to the north of an Arjuna tree, there would be water at a depth of 17½ cubits, at a distance of three cubits to its west. When the earth is dug 2½ cubits deep, there will be a white lizard ; then at a depth of five cubits, grey clay; then dark, then yellow, then white, and then sandy earth. Beneath that, abundant water is to be predicted. वल्मीकोपचितायां निर्गुण्ड्यां दक्षिणेन कथितकरैः । पुरुषद्वये सपादे स्वादु जलं भवति चाशोष्यम् ॥१४॥ रोहितमत्स्योऽर्धनरे मृत् कपिला पाण्डुरा ततः परतः । सिकता सशर्कराऽथ क्रमेण परतो भवत्यम्भः ॥१५॥ Slokas 14-15.—There will be sweet and never-fail- ing water at a depth of 11¼ cubits at a distance 3 cubits to the south of a Nirgundi (Indigo) tree with an ant-hill nearby. At a depth of 2½ cubits, there will be red fish ; then, red brown clay ; further, pale-white clay ; then, sand mixed with gravel ; beneath that, there will be water.
