original observer will be at the time.

inclusive of every detail, excluding superflu- 
ous words; and so complete that the work will 
not have to be done over again, and that any 
other member of this or any following expedi-

your daily journal, your record of photo- 
graphs, and the special jobs upon which you 
may be engaged.
