for landing on this isolated atoll is especially difficult. 11 He states further 
that he found the Jars of raised algae from the lagoon very surprising, inas- 
much as he had assumed that the water was salt hy seepage or other admixture 
from the sea. The plants he found indicated "on the contrary, that it is at 
least nearly fresh, at any rate near the surface and in the shallows, though 
probably heavily polluted with nitrogenous mat t er from the bird colonies. The 
bulk of the material was of Myxophyceae, which is appropriate under such con- 
ditions and apparently great masses of lyngbys. yemi color, must have been 
present at least near the shore. This is not & definitely marine species. 
Pith It were other Myxophyceae of cosmopolitan habits. In sparing amounts an 
undeterminable Ohara appeared, finally, four desmids wore found in consider- 
able numbers. 1 ' One of these Br. Taylor is describing as new. He remarks that 
M it should be observed that these species of deomi-’s (which ar© as a group 
intolerant of salt) showed rather weak surface markings and considerable irreg- 
ularity, so that perhaps they were adapted to slightly brackish conditions. 
This is supported by the presence of the only phanerogam associate, ??a,i&s 
marina , which is normally an inhabitant of brackish water." 
Unfortunately, w© did not obtain a sample of the lagoon water, as 
had been planned, for, although the landing was not particularly hazardous at 
the time of our visit, it was none-the-less difficult and had to be made by 
partly swimming through the surf. Our getting ashore on Cllpperton Is just 
another tribute to the efficiency of the Havy and a further instance of the 
value of their cooperation in scientific exploration. Landing In heavy surf 
Is a part of the Mavy* s routine training, end so they took the Cllpperton 
landing in their stride, as it were. 
There were so many sharks at Cllpperton that they utterly rained 
the fishing. Hot only did they destroy the few fish that were hooked, but
