BEVERLY S. RANDOLPH, M. AM. SOC. C. E. (by letter).--The percentages
given by Mr. Purdon would seem to indicate that the length of the grades
did not affect the loads in the cases cited, but these percentages are
so much below those shown in the table, for similar distances, as to
indicate some special conditions which the writer has been unable to
find in the text.
