went around in the boat. Deep water with coral heads on lagoon side. North of this about 100 yards is a second channel (the third lagoon entrance) only knee deep and in places only 15 yards wide, which extends from ocean to lagoon. The rim here is between 200 and 350 yards wide. To the north is a long level plane, covered with portulaca, boerhaavia, sida and patches of bunch grass. It is occupied by frigate birds and boobies. There is rather a marked absence of rats and lizards here. Sida is low and stunted, seldom over 2 feet high, but blossoms profusely. On it are small white microlepidoptera. A small green and orange caterpillar (probably of the small white moth), a red and fuscus ant, tiny black ant, and a Reduirolus bug. Boerhaavia forms large mats and has plenty of white blossoms. On it are white micro, a green bug, a brown and gray leafhopper, both the ants, and a small black fly (Agronyzid?) Bunchgrass, not so stunted as elsewhere. On it are a gray jumping spider, the leafhopper and Reduirolus bug, and the ants. In the roots are:- small cockroaches, sow bugs, Embyiikd, Pseudoscorpion, centiped, and small spiders. Just south of 4th lagoon entrance, a large patch of beach runner, boer- haavia bushes and a single sprig of Scaevola, run up onto the coral ridge. A long point runs out (E) into the lagoon. Here grows the tallest Sida bushes yet seen on the island, about 3 1/2 feet tall. This fourth lagoon entrance is very long and winding, having two sharp turns in it. It is rather deep in spots, but on the average not over 20 yards wide. It is crossed by two reefs of coral as shown in Roll 12:3 A picture of the 4th lagoon entrance, showing one of the two sharp bands and the two reefs referred to. Looking toward ocean from about middle. On one side of the cross reef barrier is a deep pool, which was filled with fish waiting an opportunity to swim through a break in the barrier; some jumped over it. Points of land extended out delta-like into both the lagoon
