Tus Saco-Parat or THE Aru Isuanps, New GurwzA.— The staff of life 
in these islands is sago. A good-sized sago-palm will give 1800 cakes of three 
e: d pound, of which five are the ordinary quantity ED by a man in & 
Se 
Hence a single tree may be considered equal to the support of a mi 
NEP iN the year. The labour to prepare the food is as follows : —Two m 
working moderately, will finish a tree in five days, and two women will bake. 
the whole in about five days more; so we may estimate that, with ten days. 
labour, a man may produce food for a whole year. "This is, if he possesses trees. 
of his own; for all the sago-palms are become private property, and cost about 
9s. each. POE the cost of labour being 4d. a day, and the cost of the tree 
e the expense of one year's food for a man is only 12s.— Wallace, in Pro-

New BRITISH —Mrs. Gatty, in he Appendix to ‘ British Sea- 
drawn from Pr aiao Harvey’s Phycologia Britannica, just pub- 
lished, mentions ae species of Algr not before noticed as inhabitants of the ` 
British Islands :€—1. Elachista Haydeni, parasitic on Asperococeus echinatus, 
horda Ta oa, and fasion plantaginea, found at Filey Bridge by the 
Rev. T. W. Hayden, 1862. 2. Rytiphlea owyacantha, Harvey, ms. Dr. 
Harvey now considers this as a ERU of R. thuyoides, discovered by Miss. E 
Turner in Jersey, 1855. 3. Polysiphonia fætidissima, Cocks’ * Algarum Fas- 
resembles Agardh’s Greek species D. punicea so closely, that Dr. Harvey 
believes it may be the same, although differing in one iy ore character, viz. 
in the length of the joints of the branchleteens ; those o f Agardh’s being short, 
and the present form long. Discovered by Mrs. Gray at Bognor, Sussex, 1858, : 
and 1859 by Mrs. Merrifield at Brighton. We may add, that Mrs. Gray col- 
lected the plant at Bognor i in October, 1855, and sent it to Dr. Harvey in 18885. 1 
hence the later date is given. 4. Dasya Catlovie. “A form not yet described, E. 
from the fact that only one specimen, and that a barren one, has as yet been 
found. Tt was discovered floating in St. Aubin’s Bay, Jersey, in August, 1858, — 
by Miss M. Catlow, Externally it bears some likeness to an Australasian 
At. 2. Gunniana ; but its characters come nearest to those of the Medi- P 
rranean species, D. punicea, above described as having been lately found on 
d British shores. r. Harvey considers D. Catlovie more robust, however, 
and its branchleteens more c distributed, and is inclined to think it ‘ 
may provea distinct species.” 5. Nac aria hypnoides, Agardh. St. Catherines

Cosson Line rn VULGARIS) IN MassacnvsrTTS.— That “ America 
has no Heaths” is a botanical aphorism, It is understood, however, that an 
English surveyor, nearly thirty years ago, found Calluna vulgaris in the interior 
of Newfoundland; also that De la Pylaie, still earlier, enumerates it as an inha- 
bitant of that island. But this s summer, Mr. Jackson Dawson, a young gar-
