Also see the link 'maruththa'.
Usheerabeeja was the name of a place on the slants of Himaalayas where the great king Maruththa performed his well-known sacrifice that caused fears to Indra and Brihaspathi.
After the performance, he donated all the monies to braahmanas. Details are in Aashvamedhika parva.
"After praying to Naaraayana, Nara, Sarasvathi and Vyaasa, then one should read the Jayam."
