DELAY IS DANGEROUS. 



We call attention to the new form of Accident (indem- 

 nity) Insurance policies, which are written by the Mi^r- 

 chant's Casualty Insurance Association, 21 Park Row. 

 New York City, John S. Purdy, Secretary. These policies 

 cover weekly allowances of from $10 to $25, according to 

 occupation, at a cost of only $6 a year exclusive of the 

 cost to join, which is $5 payable once only. The public, 

 as a rule, carry life insurance, and the ordinar>' accident 

 policies issued by companies, paying a sum in case of 

 death, is not so desirable as one of these indemnity policies 

 in case of accidents, which are so plentiful in this fast age 

 with its railroad horrors, fast driving, electric wires and 

 other countless forms of danger to which the public is con- 

 stantly exposed. The fact of the Association having no 

 unpaid claims, and its having just passed an examination 

 by the Insurance Department of New York State, shows 

 that the management is liberal with its policy-holders 

 and con5er\'ative in its action. The Association also de- 

 sires to secure cnerg*- iic Agents in every village and town, 

 to whom territory and favorable terms will be given.
