I have tropical fish and cannot get 
any of your Beldt’s fish food in Piqua,

a dealer here who handles it, and please 
send me your prices for 6 bottles of 
the fine fish food. 
Yours truly,

My daughter, Mrs. D. J. Freed, Du- 
mont, N. J., gave me some of your

good. Before ordering some I would 
like to have a catalog. 
Thank you.
