dinner on the other side of the forest. Jee Hock and Meng Kim were anxious to attend the dinner too.

     Blind Jee Hock thought of a plan. He would carry Meng Kim. The lame man could tell him the way. Meng

Kim said that the plan was a good one.

asked Jee Hock to carry him to the mearest tree. Upon reaching an over banging branch, Meng Kim quickly
