The notebook contains 7 double pages for the recording of data. It 
is an adaptation of a form used by Mr. M. R. Campbell for oil records, 
which in turn followed the general plan of the notebooks of the Second 
Geological Survey of Pennsylvania and of later surveys and corpora- 
tions. On each double page are seven columns, headed as follows: 
" Sample No.," "Rock or material," "Color," "Hard or soft," 
"From—," "To—," "Remarks." 
Taking and forwarding samples. — In taking, preparing, and ship- 
ping samples the suggestions in the notebooks are generally fol- 
lowed fairly closely. The samples are commonly taken every 10 
feet, or at every change of material, dried on a board or otherwise,
