 joined together by the circus master in order to 

 make it appear that the horse has himself thought 

 of looking for the handkerchief and bringing it,

 letters of the alphabet designed on pieces of thin 

 planking attached at a right angle to other pieces 

 of planking to make them stand upright and easy

 in a circle at intervals of one yard or more. To

 master with a loud voice commands the horse to 

 write a name and makes him walk round inside
