WEATHER SIGNs.-In manual of the barometer
compiled by Rear Admiral Fitzroy, and just pub
lished by the Board of Trade the following useful
observations occur Whether clear or clou dy a
rosy sky at sunset presages fine weather; red sky
in the morning bad weather, or much wind (per-
haps rain); grey sky In the morning, fair wealth
er; high dawn, wind a. low dawn, fair weather.
Soft-ooking or delicate clouds forete fine wealth
| er, with moderate light breezes; hard.edged,
oily-looking clouds, wind. A dark, gloomy, Blue
sky is windy but light, bright blue sky indicates
| fine weather.
Generally, the softer clouds look the less wind.
| but perhaps, more rain may be expected; and the
harder, more "greasy," rolled, tufted, or ragged,
the stronger the coming wind will prove. Also, a
| bright yellow sky at sunset presages wind; a pale
yellow, wet; and thus. by the prevalence of red,
foretold very nearly; indeed, if aided by instru-
ments, almost exactly. Small, inky-looking clouds
toretell rain; light scud clouds driving across heavy
masses show wind and rain; but, if alone, may ind
cate wind only
High upper clouds crossing the sun, moon, or
stars, in direction different from that of the lower
| clouds, or the wind then felt below, foretell a
change of wind. When sea birds fly out early, and
| TAR to seaward, moderate wind and fair weather
may be expected; when they hang about the land,
or over it, sometimes flying inland, expect strong
| wind with stormy weather. There other signs
| oil coming change in the weather known less
generally than may be desirable and, therefore,
worth notice; such when birds of long fight,
| rocks, swallows, or others, hang about home, and
ny up ana GOWN or low-raln or wind may be ex-
pected.
Also when animals seek sheltered places instead
of spreading their usual range; when pigs
carry straw to their sites; when smoke from chin
neys does not ascend readily (or straight upwards
during calm) !, unfavorable change is probable.
Dew Is an indication of fine weather. so is fog
Neither of these two formations occur under an
overcast sky, or when there is much wind One
sees fog occasionally rolled away, as it were by
wind, but seldom or never formed while it is blow
ing.
A New SrEAM-P Iowa steam plow of later and
more novel construction than any that has yet been
tried, made its appearance on the Missouri Fair
Grounds on Thursday last. The St. Louis Democrat
| thus describes the machine: 40 El'.+
This steam.plow was made at Hannibal, Mo-, and
has been brought thence to our Great Fair. 1t was
built last spring by Mesars. Steam & Roberts, upon
whlch is claimed, as new principle, that of apply
ing the locomotive power near the periphery of the
whees. Mr. Robt. L.. Steam, the first above named,
| Is the inventor, and has filed an application for
patent in the case. The machine weighs seven
tons, and is twenty feet long by ten wide while the
forward wheels are twenty inches in width. 1t is
guaranteed TO plow thirty acres of land in day =
and the sanguine managers believe it capable of
plowing forty. The steam-plow left Hannibal at IL
o'clock, A. NJ, Monday last. on barge rugged with
paddles, which the steam-wagon was made to move
This is curious combination, in which barge
carries wagon, and the wagon propels the barge
The odd hermaphrodite craft excited much suspi-
cious auguring among the boatment ON the river,
despite which it arrived duly atfve O'Clock Monday
evening. The wagon being at last eliminated from
the barge, first "astonished the natives" on Carr
street yesterday morning. 1t then took up its
march for the Fair Grounds, passing down Broad
way and out Wash street, and causing more aston
ishment than Baron Renfrew himself. Being a
wagon twenty horse power, it of course found no
difficulty in getting along. .a E
To-day the practical proof of the merits of this
steam plow is to be exhibited upon the tract west
of the Fair Grounds
COTTON PLANTERS FAlR.-The President of the
Cotton Planters Convention, in a letter, states
thst no article invention will be permitted in the
Fair it the manufacturer or inventor resides in
Northern State. The President adds: 'sIt is ne
cessary that this course should be pursued in order
that hereby the consistency of the future action of
the convention may be preserved"
