unexplored. Early In 1923 arrangement was male with the Navy Department 
for transportation and other assistance, and a cooperative expedition 
was organized hy the Biological Survey and the Bishop Museum, of Honolulu 
for a complete scientific exploration of the islands in question. On 
April 4 a party of twelve left Honolulu on a thousand ton Naval mine 
sweeper, the U. 3, 3. Manager, with whose aid*travel among the outer 
islands oantlnned until the middle of August, 
Definite plans had been made for the prosecution of as many 
lines of scientific wort as practicable. Workers in our party included 
a botanist, an entomologist, a geologist, a conchologist, an ornithologist, 
one or more to collect fishes, miscellaneous marine animals and plants, 
men occupied with studies of ruins left by man, a topographer to mate 
maps and one or two general assistants. All were armed with oameras, 
while in addition, an expert in motion and still photography of birds 
accompanied the party to Laysan Island. The present writer as represents*- 
i 
tive of the Biological Survey had charge and direction of the wort of the 
scientific party. 
(tex addition to our efforts the officers of the Tanager under 
Lieut.-Cotnaander 3. W. King and Commanding Offloer Stephen Ingham made 
many observations of positions and soundings and secured much additional 
data for the correction of existing charts,' Seasonal changes in weather 
made it expedient to wort the farther islands early in spring and shifted 
our program so that no regular itinerary was pursued. In the present 
narrative to avoid confusion the various roots and atolls are taken up 
in geographical sequence beginning with those nearest to Honolulu.
