Some propositions having been made to the public on the subject of a natural bed of Sulphur in Genesee, we wished to obtain information respecting it.

5From Thomas Jefferson to Benjamin Smith Barton, 14 February 1805 (Jefferson Papers)
Your favor of the 1st. inst. has been longer unanswered than I could have wished. the correspondence between Dr. Priestly and myself was unfrequent & short. his fear of encroaching on my public duties deprived me of communications from him which would have been always welcome. I have examined all his letters to me since Mar. 1801. (those preceding being at Monticello) & find they do not...
