Typed letter, dated October 6th, 1897, on Penn Mutual Life Insurance Company stationery:
Charles Hamilton Jr.
West Walnut Lane
I regret very much that I will not be able to be with you on Saturday, but as I have another engagement for that evening it will be impossible for me to come.
I hope you will win all their money and illustrate to the boys that they know nothing about the game whatever.
Hoping to see you again soon in the near future,
Francis W. Slaughter
