Among the Marian islands, Guaga is well wooded, and its flora 
rich. Forests clothe its steep descents to the sea-shore, and in se- 
veral sheltered spots, the Mangle trees dip their pendant boughs 
in the flood. Orange trees, and other memorials of a once flourish- 
ing cultivation, grow wild. The Bread fruit, Cocoa, and Pisang, 
are abundant: the Mango grows well, but is not naturalized. Two 
species of Pandanus, and many kinds of Fig, are natives of Guaga. 
The flora of Radack-Ralick, Repith-Urur, and Bogha, is scanty. - 
The most useful Palm is the common Pandanus, or Screw pine of 
the South Seas, and next to it the Cocoa tree holds rank. The 
Bread fruit tree is not very common. 
A number of useful Palms are cultivated on the Caroline Islands. 
All these islands are rich in Bread fruit trees, Bananas, and escu- 
lent roots. The orange, the sugar-cane, and the Curcuma, also 
thrive ; the cloves are not esteemed. 
In the Isle Romanzoff the Russian naturalists found only nine- 
teen species of perfect plants, (one Fern, three Monccotyledonous, 
and fifteen Dicotyledonous.) 
The vegetation of the Sandwich Islands, having nothing in com- 
mon with the adjoining continent, is more interesting. The plants 
collected by Archibald Menzies, in his expeditions to the heights 
of Q-waihi and Mauwi, are still, we believe, undescribed, though 
a long time forming part of the herbarium of Sir Joseph Banks, 
Of the vegetation of Kamtschatka we have not room to say much: 
the arborescent birch is stunted, and very different from the slen- 
der elegant tree of the north of Europe. Pinus cembra, which on 
our Alps grows at greater heights than P. abies, remains quite 
shrubby. Grapes and herbaceous plants thrive luxuriantly, the 
soil being rich, and the sky mild. There are but few species of 
vegetables, and these seem about equally distributed. The genera 
of plants are generally the same as those of northern Europe : their 
proportions, however, differ, and the mountains of these dreary 
climes being unprotected by any covering of vegetation, soon de- | 
compose. The frost bursts the rocks, every summer’s gentle warmth 
causing fresh ruins, and so destruction hastens towards its comple- 
tion. 
Tt will thus be at once perceived that Dr. Hooker, a host in him~ ° 
self, with the assistance of such men as Mr. Frazer, Dr. Gillies, 
Dr. MacFadyen, and cther correspondents abroad, has been able to 
give to the world more impertant botanical matter, in a given time, 
than any society in Europe, including even those devoted to horti- 
eultural or botanical pursuits. This is the greatest compliment we 
can bestow on this periodical; and we can only terminate by hop- 
ing that the reports we have heard, of the public not having an- 
swered the publisher’s expectaticns, in giving due support to a va- 
inable, and consequently rather expensive work, are unfounded, 
and that our library will be adorned with many a future volume of 
a publication reflecting so much credit on the labours and taste of 
our countrymen,
