hus, according to Mr. T. D. Brewster, of Assam, 
_Silkworms also live on it. 
Calamus montanus, T. Anderson. — Himalaya, 
up to 6,000 feet. A hardy, climbing palm. The 
aged canes are naked. ‘+The light but strong sus- 
pension bridges, by which the large rivers of Sikkim 
are crossed, are constructed of this palm. It supplies 
material for the strongest ropes for dragging logs of 
wood from the forests. The most durable baskets 
and the cane-work of chairs are manufactured from 
the slit stems. Walking-sticks and riding-canes made 
of this species are exported from Sikkim in consider- 
able quantity.”” Many other Calami serve similar 
purposes, but probably few or perhaps none are equally 
hardy. 
Camelina sativa, Crantz.— Middle and South Eu- 
rope, temperate Asia. An annual herb, cultivated 
for the sake of its fiber and the oil of its seeds. It 
is readily grown after corn-crops, yields richly even 
on poor soil, and is not attacked by aphis. Mr. W. 
Taylor obtained 32 bushels of seeds from an acre, 
and from these 540 pounds of oil. The return is within 
a few months. 
Canna Achiras, Gillies.—Mendoza. One of the few 
extra-tropic cannas, eligible for arrow-root culture. 
Canna coccinea, Roscoe.— West India. Yields, 
with some other cannas, the particular arrow-root 
called «¢ Tous les mois.”’ 
Canna edulis, Edwards,—The Adeira of Peru. One 
of the hardiest of arrow-root plants, and thus well 
adapted for our clime. Seeds, even if many years 
old, will germinate. This species has yielded excel- 
lent starch at Melbourne, Western Port, Lake Wel-
