If the phenomena referred to above should occur when the Sun is in the sign Meṣa (Aries)-April-May, a tradesman shall purchase the produce of Śarat; and if the phenomena should occur when the Sun is in Vṛṣabha (Taurus), he shall store up wild roots and fruits; and if he should dispose of these articles in the fourth month after purchase, he will make much profit.
