originally built with woodpilings and ranged from 18 to 32 ft in
width. The area between the pilings was filled with stone and tim-

The north pier was rebuilt with timber pilings similar to the origi-
nal construction.

Construction of the north and south breakwaters (Figure 130) was
completed. (Figures 130, 131, and 132 illustrate structures at

that was capped with 8- to 10-ton
