242 SPENCER FULLERTON BAIRD 
remember on one occasion a mineralogist, who had been 
much interested in the subject of artificial building stones, 
was at our house together with another gentleman, not 
a scientific man, but who to some extent followed scien- 
tific progress. ‘This latter gentleman asked a question 
about some very recent discovery, to which the specialist 
replied that he was not sufficiently acquainted with the 
subject to give the desired information. My father 
turned the question away, as far as it was addressed to

had a cottage there. In the train he found Mr. George

After some little conversation, Mr. Childs asked him to 
contribute a scientific column, or, to speak more exactly, 
about half a column, each week to the Philadelphia 
‘Ledger,’ giving items of scientific interest. My father, 
who was modest as to his literary abilities, as in every- 
thing else, felt so sure of his inability to write popular 
paragraphs agreeably that he was inclined at first to
