and masonry similar to those of the Rivanna aque
duct with such variation only in form as was demand
ed by the popularity Of its situation The course Of
the canal in this instance not being at right angles to
the course of the river, the lock being placed at an an
gle of p degrees with the same the form of the ma
sonry was modified accordingly; the faces OF the abu

By lock No % we rise 81 feet TO the hirticth level
which is u miles and 81 yards long. The excavation
