ues observed on the islands of the Hawaiian 
group. 
Johnston L has absolute Bouguer anomaly 
values that are somewhat lower than those of 
the Hawaiian Islands. These values are inter- 
mediate between those found on the Hawaiian 
Ridge and on the remainder of the Line Is- 
lands where R. Mason (personal communica- 
tion) reports absolute anomaly values ranging 
from +145 to +175 mgal that can be related 
to the island platform configuration, with no 
evidence of a feeder pipe contribution in the 
anomalies.
