634 THE AMERICAN NATURALIST. 
especially of the migration of ocean birds, have been made here by 
Mr. Leverett M. Loomis, of the California Academy of Sciences. 
The botanist, too, finds much of unusual interest on this bit 
of Pacific coast and in the bay and ocean waters of the shore. 
The Monterey cypress and Monterey pine, two conifers so 
restricted in their range as almost to warrant the statement 
that they are to be found naturally only on this little promon- 
tory, are the characteristic trees of the region. The cypress is, 
indeed, found only here, but the pine has a range of a hundred 
miles, perhaps, along the coast. Point Pinos is, however, the 
center and the principal point of its occurrence. In the shore 
waters the botanist is at once impressed with the abundance 
and enormous size of the brown kelps. Macrocystis pyrifera 
grows to the length of 1000 and 1500 feet; Nereocystis is 
nearly as large. A number of these brown kelps are mono- 
typic, and are found only on the Californian coast. Among 
these forms is the interesting sea palm, Postelsia, which grows 
abundantly on the surf-swept rocks. The red algz, too, are 
present in great abundance. In fact Professor D. H. Campbell 
says that in his acquaintance with the shore waters of America, 
Europe, Japan, and the West Indies he has found nowhere 
else so great a number of species, nor so enormous an abun- 
dance of individuals, as are displayed in these waters. 
The laboratory’s regular sessions are held in June and July of 
each year, but investigators and students working without instruc- 
tion may continue their work through the summer. Courses in 
general zodlogy, embryology, and cryptogamic botany are regu- 
larly offered, with special courses and lectures depending upon 
the personnel of the instructing force. The instructors are chiefly 
members of the biological faculty of Stanford University. Stu- 
dents taking the regular courses are charged a fee of twenty-five 
dollars ; investigators prepared to carry on original work are 
permitted the use of the laboratory and its equipment free of 
charge. There are seventeen private rooms for investigators. 
The Hopkins Laboratory has a point in common with the 
Naples Station, which should not go unremarked. The lab- 
oratory can be used to advantage at any time in the year. The 
mid-year holidays always find a group of workers there.
