Walled Fish Traps of Pearl Harbor

from the marine growth, are much older than the latter. On the 

 walls of the pa makiawa at Puleou, no dark stones were observed, 

 but a few were seen on the outer wall of that at Keanapuaa, and 

 none on the side walls. 



From rough soundings made, it was observed that the corre- 

 sponding depth of water inside and outside of the fish traps did 

 not appreciably differ. In the plans, the depth at low tide is 

 marked in feet. Some months ago when sections of the north and 

 south walls of the Pakule were removed (as seen in Figs. 7-10) it

was found that the stones were lying on top of the sand bank and 

 that conditions were the same as at the time of building. The 

 writer is waiting to watch the removal of the heavier outer wall. 



It is interesting to note what advantage of natural conditions 

 was taken by the early fishermen in constructing their traps on 

 the banks jutting out into the channel. In referring to the map, 

 it should be remembered that the pa makiawa at Bishop Point 

 was merely drawn in from description. The natives say that 

 the incoming tide flows more strongly against the east side of the 

 channel, while the west side bears the heavier proportion of the ebb. 

 To reap the full benefit of this condition, the entrances of the pens 

 were built opposed to the stronger current.
