may be divided generally into water courses, mountain
ridges [&?] plains [&?] each specifically as follows.

nal detours [&?] frequent halts. 2nd  The [mountain?]
ridges may dip [           ] [&?] the [intervening?] valleys
[               ] as to be almost or wholly unpassable 
[&?] frequent fissures may occurr [ insurmount ? ]
[ able? ] in any other way than by [ tracing ? ] them
to their termination.
