C. G. Loran Station, Sand Island, Johnston Island Atoll Chief Gragosian brought no more centrifuge tubes so we washed out the old ones and borrowed the doctor's sterilizer to finish cleaning them. I discovered that he had brought some syringes, but they were 5 CC so some of our 10 CC were brought out. After dark Chief Gragosian and I went out to collect sera and spleen from Shearwaters (Wedge-tails). I took the first blood sample and we then killed the bird, cut it open, and took out the spleen. Chief Gragosian brought fixing fluid in vials for storing the spleen, but it has to be refrigerated at all times. Chief Gragosian tried unsuccessfully to take the second bird's (through the fifth) blood. He is use to taking human blood and this is a new and different process!!! After five birds I decided to stop for the nigh since I saw Chief Gragosian was getting tired from kneeling on the ground working. He is not use to working in the field and especially not at night. Ken Wilz banded one hundred adult Sooty Terns. This now makes a toastl of twelve thousand. Saw first White-tailed Tropicbird at noon today. It circled over the station several times. August 15, 1963 Chief Gragosian made shipping arrangements from here to Hickum through Captain Thompson (Head, Mats Terminal, Johnston Island). Equipment was gotten together for use tonight during the afternoon. After dark we began processing Shearwaters. Ken caught the birds and held them down while I took the blood samples.
