252 बृहत्संहितायाम् [Adh. XXVIII. Sl. 15-18. पर्यन्तेषु सुधाशशाङ्कधवला मध्येऽञ्जनालित्विषः स्निग्धा नैकपुटाः क्षरज्जलकणाः सोपानविच्छेदिनः । माहेन्द्रीप्रभवाः प्रयान्त्यपरतः प्राग्वाम्बुपाशोद्भवा ये ते वारिमुचस्त्यजन्ति नचिरादम्भः प्रभूतं भुवि ॥१५ Sloka 15.—If the clouds are as white as chunam or the Moon at the edges, as dark as collyrium or bees at the centre, glossy, have many folds, (i.e., appear piled up) dropping particles of water, and breaks like the steps of a stair-case, and being formed in the east sail westward or vice versa, they yield plenty of rain to the earth before long. शक्रचापपरिघप्रतिसूर्या रोहितोऽथ तडितः परिवेषः । उद्गमास्तसमये यदि भानोरादिशेत्प्रचुरमम्बु तदाशु ॥१६॥ Sloka 16.—If at sunrise or sunset there is a rain- bow, a cross bar of clouds, a mock Sun, a straight frag- mentary rainbow, flashes of lightning, and halos round the Sun and the Moon, it should be predicted that there will be plentiful rain in the near future. For the definition of रोहित vide Adhyaya XLVI-20 infra. यदि तित्तिरपत्रनिभं गगनं मुदिताः प्रवदन्ति च पक्षिगणाः । उदयास्तमये सवितुर्द्युनिशं विसृजन्ति घना नचिरेण जलम् ॥१७॥ Sloka 17.—If the sky bears the tinge of the wings of the Tittira bird, and groups of birds twitter merrily at sunrise and sunset, then the clouds will pour down rain soon by day and night respectively. This verse is spurious, says the commentator. यद्यमोघकिरणाः सहस्रगोरस्तभूधरकरा इवोच्छ्रिताः । भूसमं च रसते यदाम्बुदस्तन्महद्भवति वृष्टिलक्षणम् ॥१८॥
