In James Teit's collection of Thompson River traditions, a figure called NLi'ksEntEm travels to the upper world, where his grandfather the Spider instructs him in all manner of knowledge and magic. When he returns to the earth, the Spider lowers him through a hole in the floor of his underground lodge.
The Nkamtcí'nEmux (the people around Spences Bridge) say that through this hole, the people at Lytton could be seen playing ball underneath, appearing in the distance to be as small as flies. The Spider declared that the place where NLi'ksEntEm first touched the ground would be the centre of the earth — the centre of the Indian's country.
The Nlaka'pamux hold the stone marking this spot sacred, and at the time of Teit's writing kept it covered with earth so that others would not see it.
