Eduyos 7:4

Rabbi Tzadok testified that flowing waters that a person channeled through nut shells are fit (for immersion and for use in the red heifer ceremony, as above). This actually happened in a place called Ahaliya and the Sanhedrin permitted it.

Eduyos 7:5

Rabbi Yehoshua and Rabbi Yakim of Hadar testified that a clay jar containing the ashes of the red heifer that was placed on a creeping thing (sheretz) is ritually unclean, though Rabbi Eliezer says it is ritually clean. Rabbi Papias testified that if one committed to two terms as a nazir and he shaved for the first on the 30th day, then he shaves for second on the 60th day. If he shaved on the 59^th day, he has fulfilled his obligation, because the 30th day is included in both nazir periods.
