practically unaffected, and trains could be run with little difficulty 
almost immediately after the shock. On the Atlas Wharf, however, 
the tracks were warped slightly and had to be relaid. In the city 
a few trolley poles appear to have been titled by the shock, although 
the greater part were bent by falling débris. In the country few 
trolley or telegraph poles were affected, generally remaining upright 
even where near the sea. The sway of the poles seems to have been 
considerable, nevertheless, many of the wires being snapped, especially 
in the district east of the city. 
Rockfort District 
Rockfort is the name applied to the old fort at the government 
quarries on the coast some three miles east of Kingston. A number 
of artificial structures were disturbed in this region, principally 
between the fort and the small stream entering the harbor beyond 
the old Naval Pier half a mile west of the quarry. At the mouth of 
the stream mentioned the cement culvert was much damaged, a part 
being buckled up and faulted (Fig. 11) while other parts were pre- 
_ cipitated into the stream. At the same point the gutter was faulted 
downward several inches along the edge of the sidewalk. It is 
interesting to note in Fig. 11 that the wooden house, although near 
the region of greatest disturbance, is little affected. 
Along the water front near here the sewer, a large iron pipe, was 
broken by the shocks, presumably by a buckling in the deposits. 
Port Royal 
Owing to the failure to get a permit to visit the fort the observations 
were mainly made from the water. The wooden tower at the south- 
west terminus is tilted 4 or 5 degrees from the perpendicular. One 
_ of the wharves on the harbor side appears to have been tilted toward 
the land at a considerable angle, the outer end being several feet 
higher than the inner. A railroad track was arched for a distance 
of twenty-five yards, the center being four feet above the ends. The 
sea wall was disturbed and tilted. Many buildings were severely 
wrenched and partially wrecked, the fact that the damage was not 
greater being due to the fact that they were of the frame type. One 
building was noted broken in two where the middle had sagged owing 
to a depression formed beneath it while the two ends remained elevated.
