ADVERTISEMENTS. 



THE POSTAL EXCHANGE CLUB. 



The boxes are now on their travels, after being detained by one of the members several ,| 

 weeks on their last circuit, which I trust will not happen again. A few more members are| 

 wanted to fill another set. Will any one desirous to join please communicate, and say J 

 whether they collect other orders, or Lepidoptera only ? Announcements will be made | 

 here every month in future, and members are urged not on any account to detain the box^ 

 beyond the time allowed. Will every member please advise by post card when the boxes | 

 leave them. All communications to be addressed— JOHN E. ROBSON, Hartlepool.
