Tos B’M ??? ??????. Bottom of bais amid aleph.
I’m not to good at writing Hebrew. I’ll translate here. You can check on my translation.
“And this that it says later daf 118 aleph, that seeing Hefker is koneh. This is that he did some maaseh such as that he fenced it in with a small fence.”
I guess some maaseh that isn’t an actual kinyon, otherwise what does the seeing accomplish.
