The maximum grade and minimum m

the expense of grading will be moderate. aS
may be seen from the fact that (wiih few e3,

not require very material alteration (by an

This will place before you the maximum
grade, the number OF miles at different rates
per mile and in fact furnish the most lmpor
tant information that can DC communicated
at this time, by which the general character
oi' the route may be seem Inc grades that
b.ve becn adopted are such as are naturally
indicated by the general formation Of the

difficult parts of the route Tie arrange
mcni that has been made with the grades
may be considered favorable from this fact
viz The extent of the route upon which
grades from 80 10 60 feet per mile will be re-
quired, is confined TO a continuous part ofthe
route of which 10 miles is west and l3 miles
east of the summit Mount Holly Upon this
