101. 23 Jan. (cont.) Laysan. Thus it seems that rats are important in this condition - we do not know for sure that they bring it about. QUESTIONS: 1). Why the localization of the disease to the SAF, with tendencies now for a spread? 2). One Laysan found dead and collected, was sub- sequently skinned and found to have a small hole, 3/4" in diameter, in its back. Is this truly a disease that caused the death, appearing to our eyes as a small hole (that rats later develop further), or did the bird get bitten there and get infected or die to some non-related cause???? We should have a better indication from autopsy of collected specimens and blood. Two small pinkish-white eggs, presumably Bonin's, were found on the ground today in widely separated areas - one in NAF and the other near south Point in the Scaevola. Both of the feathers are from live, healthy-appearing incubating Laysans. The backs of the birds were examined - the stubs remain. No sores present. 44F Laysan #1 Laysan #2
