 Dear Sir


 There can be no difficulty in 
 making the arrangement you propose. The report upon the
 plants collected by Mr Blake can just as well accompany the
 part of Williamson's volume in which Mr Blake's own report is
 to appear. The printer will probably commence the latter on
 Monday or Tuesday, and will, if he continues upon it
 without interruption, finish it in three or four weeks. The
 9th volume will then be all printed with the exception of 
 your report, which the printer would therefore desire to have
 by that time.


 The whole of Whipple's report is now printed, excepting
 the latter part of the Botany which includes your report. I
 have received two forms of Dr Engelmann's report, which precedes
 yours, and presume that they will be ready to commence
 your report on Monday.


 Dr Newberry has been engaged by the office to
 correct the proof of the Botanical Report of Dr Engelmann
 and that of Durand and Hilgard. It would save
