THE POSTAL EXCHANGE CLUB. 



I am obliged to allow this Club to suspend its operations for a short time, 

 so many of the members have exhausted their duplicates. I have tried by 

 changing names to keep one or two rounds going, but it is getting rather 

 " mixed " now. I propose the Club shall resume in May, and assume that all 

 the old members will continue, if so I have nearly enough names to make a 

 fourth circuit, and would be glad to hear from one or two more to fill the list. 

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



ALBO-OARBOH, 



A SUBSTITUTE FOR NAP1H ALINE. 



I have had many enquiries where and how this preservative may be obtained, 

 as it is very much cheaper than JSFapthaline, and is said to be equally effective. 

 It not being an article of common sale, 1 have procured a quantity, and will 

 supply any one wanting it at 6d. for 8 ounces, post free.
