He (the Adhvaryu) then says, 'Brahman, I shall step forward.' Thereupon he puts the stick (reserved at the time of kindling) on (the fire), and says, 'Agnîdh, trim the fire!' He then takes the two spoons and crosses over to the west side. After crossing over and calling for the 'Sraushat,' he says (to the Hotri), 'Pronounce the offering-prayer to the gods!' He performs two after-offerings, omitting the one to the Barhis; for the Barhis means offspring: hence he performs two after-offerings, omitting the one to the Barhis, lest he should consign his offspring to the Fathers.
