The year 1884, after my return from Mexico, and the 
succeeding year, 1885, passed without any particular thrill 
or event of importance other than the current expositions. 
The work of exploration and preparation of reports and of 
special papers was kept up and carried forward as usual, as 
briefly indicated in the extracts from the annual reports of 
the Bureau, copies of which are enclosed herewith. All may 
be found in extenso in the reports of these years, and in 
♦ . 
certain other publications.
