REMARKS ON COLLECTING INFORMATION.*
General.
Any proceedings likely to offend foreign susceptibilities
should be scrupulously avoided.
It is most important to be exact, especially in figures. Any
doubt as to the accuracy of information should be clearly
expressed. It is important to state how and where an object
reported on was observed.
Vague relative terms such as “ right,” “ left,” &c. should be

and the original or a tracing, should be attached to the report.
The report, which should supplement the map, should be clear
and concise.

in this book, the same order of subjects should be adopted to

additions to tabular forms. In the case of defence works the
statement of armament should be clearly separated from the
description.
Names of places, &c. should be given in block letters the first
time they occur. When local spelling is found to differ to any
