Translation:Mishnah/Seder Zeraim/Tractate Orlah/Chapter 1/4

Introduction
What happens when a tree is uprooted but one root remains?

Hebrew Text
אילן שנעקר, ונשתייר בו שורש--פטור. כמה יהא בשורש--רבן שמעון בן גמליאל אומר משום רבי אלעזר בן יהודה איש ברתותא, כמחט של מיתון.

English Translation
If a tree was uprooted but one root remained [connected to the ground], it is exempt. And how large must that root be? Rabban Gamliel says in the name of Rabbi Elazar the son of Yehudah of Bertota: As [the thickness of] a stretching pin [used to stretch cloth].
