Abie M asks:
What is considered a weak tree?
Answer (d'Vei R. Yanai): At the trunk, it is too thin to carve out a quarter of a Kav.
What does that mean where do you measure? Through and through I just dont understand this whole line if you can please explain it broadly... Thnaks!

The Kollel replies:
What the Gemara means is that the trunk of the tree is too small to carve in it a hole that can hold a quarter of a Kav.
