ROCK, THE
  1. was something which we audited for and assessed out, meaning a shape of something which we could then run a process on. We at that time were running on the theory that it was the first object the fellow had made on the track. (SH Spec 83, 6612C06)
  2. that which a person has used to reach people or things with and is determined in value by its creativeness or destructiveness. It is simply a reach and withdraw mechanism which makes a ridge and this causes the stick of the needle. The rock is an object not a significance. (HCOB 29 Jul 58)
