First listen and then answer the question: What does 'No wrong numbers' mean?
Mr. James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst.
Pinhurst is only five miles from Silbury, but Mr. Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons.
Yesterday, a pigeon carried the first message from Pinhurst to Silbury.
The bird covered the distance in three minutes.
Up to now, Mr. Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other.
In this way, he has begun his own private 'telephone' service.
