snuhikṣīraliptāni dhānyāni visṛjed, upaniṣadyogayuktāni vā //

With a view to destroy rats, grains mixed with the milk of the milk-hedge plants (snuhi: Euphorbia Antiquorum), or grains mixed with such ingredients as are treated of in the 14th book may be left on the ground. Asceties and prophets may perform auspicious ceremonials. On new and full-moon days rats may be worshipped.
