Hulton, Penn., December 28, 1893.

...Please thank dear Miss Derby for me for the pretty shield which she sent me. It is a very interesting souvenir of Columbus, and of the Fair White City; but I cannot imagine what discoveries I have made,--I mean new discoveries. We are all discoverers in one sense, being born quite ignorant of all things; but I hardly think that is what she meant. Tell her she must explain why I am a discoverer....
