“ Saturation ; ” but Simmons’s was faithful to the duty ex¬ 
pected of it, and continued to indicate increasing dryness 
as the vapour suspended in the air diminished. Without 
pretending to explain this puzzling circumstance, it must 
be taken as valuable testimony to the efficiency of Mr. 
Simmons’s Hygrometer. 
Two of the instruments are in use in the Society’s 
Garden, and continue to give satisfactory indications. 
“A slip of wood is cut transversely with the grain, of about, or vary¬ 
ing trom six to seventeen inches in length, according to the absorbing 
property of the wood employed ; one end of the slip (BBB) secured to 
] the frame or fabric (AAAA), at pin '(C); but on the other end of the slip 
(B) is fixed a pulley (D), which is kept in its position by a line (a a), 
one end of which is secured to the frame or fabric by the hook (A), and 
passing through the pulley (D) affixed to the slip (B), thence round a ! 
small pulley (c) of about two-tenths of an inch in diameter, the axis of i 
which carries a hand (E) to indicate on a dial (FF); inside, and affixed on | 
the same small pulley, is another pulley (d) of the same size, and on the [ 
same axis, having a line (e) on it, drawn by a weight or spring (G), 
which pulls up the slip (B) tight; yet by its tension allows the dilation 
or contraction of the slip in its changes, giving motion to the hand in¬ 
dicating on the dial. 
“ The improvement claimed in this instrument consists in adapting 
the changes produced by moisture upon wood with a line through the 
medium of pulleys to give a legible indication to a hand on a dial, which 
renders it portable and convenient for scientific purposes and domestic 
usefulness.”

PINUS ORIZABA. 
Received along with Pinus cembroides 
from Mr. Hartweg, who collected it on the 
mountain of Orizaba, where it forms a tree 
of moderate size. 
Leaves in fives, from eight to nine inches 
in length (on the wild specimens), very 
slender, sharp pointed, triquetrous, thickly 
set on the branches, very rough at the 
edges, of a light green colour, and much 
resembling those of Pinus Pseudo-Strobus. 
Sheaths persistent, about half an inch in 
length, rather smooth, and entire. Seed 
leaves on the young plants from seven to 
eight in number. Branches numerous, 
spreading rather irregular, slightly in¬ 
curved, and slender. Bark rather rough. 
Buds large, light brown, much imbricated, 
and destitute of resinous matter. 
Cones in clusters of four or five, pen¬ 
dulous, from four to five inches long, and 
two and a half inches broad at the base, 
straight and tapering to a point, with a 
footstalk nearly an inch in length, and 
from twelve to sixteen rows of scales in 
each, which are much elevated, slightly 
hooked, and nearly all of a size, but rather 
smaller towards the extremities. They 
measure about half an inch across, and 
each scale contains two very small seeds, 
with wings nearly an inch in length. 
This Pine is very distinct from any 
previously known; it resembles the Pinus 
Pseudo-Strobus in habit and foliage, but 
differs entirely in the cones, which much 
resemble, but are not half the size of, 
those of Pinus niacrophylla. 
No evidence has yet been obtained as 
to the hardiness of this species.—( Horti¬ 
cultural Society's Journal.) 
NOTES FOR MARCH. 
As this is the best month for a general 
sowing of kitchen-garden crops it is recom¬ 
mended to make sowings of the following 
vegetables in small beds, in a warm, 
sheltered situation in the open ground: 
—Savoys, Brussels Sprouts, Green Kale, 
Chou de Milan, a few early Broccoli, early 
Cabbages, a small quantity of Cauliflowers, 
Leeks, and Stone Turnips, and frequent 
sowings of Radishes; Lettuces, which must 
be covered with litter in frosty weather; 
Early Horn Carrots, Mustard and Cress, 
and succession sowings of Broad Beans 
and late Peas; Knight’s Dwarf Marrow 
and other such good sorts should be made | 
wide apart, with other vegetables between. 
The early-sown Celery must be pricked 
out on a bed five or six inches thick of 
rotten dung on a hard bottom, with an
