exposed rocks, so unless the weather is very calm it is rather difficult 

 to secure in large quantities. 



Limu oolu grows in shallow water near shore or farther out on the 

 shallow sand-covered reefs where the water is quiet, hence is quite 

 easily gathered, but it occurs in rather limited quantity in but a few 

 places. 



All the other limus are more difficult to gather and also occur in 

 more limited quantities and in but few localities. This is especially 

 true of limu luau, which is extremely difficult to collect and is very 

 scarce. It grows only on the most exposed and slippery rocks, and 

 disappears in a few days after the stormy weather subsides not to 

 reappear until the next season immediately after the heavy winds. 

 Therefore this much -prized limu is always most difficult to obtain even 

 in very small quantities. 



Limu kohu, which is so eagerly sought, grows usually far out on 

 the exposed rocks or on coral reefs, where the breakers dash, so is 

 rather difficult to get even in quiet weather and impossible in heavy 

 storms. Occasionally, however, it grows on reefs less exposed and 

 more accessible. 



Limu lipoa is limited to certain localities, and occurs in rather small 

 quantities. It grows in rather deep water, so usually can be gathered 

 only by diving or swimming. It is found in small quantities on all. 

 these islands, and is a general favorite. 



Limu huna and limu manauea are often drifted upon the beach by 

 the heavy winds or high tides, and may be very easily gathered in 

 boat loads by wading along the shallows at low tide and gathering 

 up the drift on the shore and at the water's edge. It is especially 

 abundant where there are very wide coral reefs under shallow water 

 and a sandy bottom. There are tons and tons of these two limus on 

 the south coast of Molokai, south and east Kauai, and almost all 

 around Oahu, except off Kaena Point and in the harbor, where the 

 water is too deep or muddy for seaweeds to thrive. Wherever there 

 are shallows or reefs off Maui it is also plentiful, though not in such 

 large quantities as the other islands mentioned, because of a less 

 favorable coast. 



Limu manauea and limu huna are most abundant in early spring 

 and during the summer months, though both are found in consider- 

 able quantities all the year, as would naturally be expected in a 

 tropical region. 



Limu loloa can be secured in large quantities all the year round on 

 Molokai, Oahu, Kauai, and Maui, but is not so abundant on Hawaii. 

 It grows on the great lava rocks exposed to waves, so in heavy storms 

 it is difficult to secure. 



Limu akiaki (PI. VII, fig. 2) may be obtained by boat loads all the 

 year, if not too stormy, as it also grows on the great black lava rocks
