Thank you!

Question

Answer

1) I don't know the word"すろと"  
     Isn't it "すると"?
2) こゆびくらいの
I think it's describing the size of something.
"こゆび" is the little finger,  "くらいの" means about,
So "こゆびくらいの" means the size is about the little finger.

I hope it help you understanding the book.

3) おつこのこが
