[Footnote 48: Alexandria, Virginia.--This seems to be a brief
record of the course and distances of a survey by Washington of
the shore-line of the town of Alexandria before the river bank was
improved or altered by the building of wharves and the grading of
streets. It is probable that these lines were run in the winter
when the river was closed with ice.]
