Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Told by the chief priest “Now offer oblations,” the person in charge of oblations took clarified butter to offer. He then remembered the request of Manu’s wife and performed the sacrifice while chanting the word “vasat.”
