Preview of English translation:

8. He (the Adhvaryu), having called (on, and having been responded to by, the Agnidhra), says (to the Hotri), “Pronounce the offering-prayer (yajya) to the Samidhs (kindling-sticks)!” Thereby he kindles the spring; the spring, when kindled, kindles the other seasons; the seasons, when kindled, generate the creatures and ripen the plants. In the same (formula) he also implies the (four) remaining seasons, and in order to avoid sameness, he introduces the others by merely saying each time, “Pronounce the offering-prayer!” For were he to say, “Pronounce the offering-prayer to Tanunapat!” 'Pronounce the offering-prayer to the Ids!' and so on, he would commit (the fault of) repetition: hence he introduces the remaining (seasons or fore-offerings) by merely saying each time, “Pronounce the offering-prayer!”
