WOODRUFF'S IMPROVED PORTABLE
BAROMETER

[ocr errors][ocr errors]

Is now regarded as an indispensable instrument by every
intelligent farmer. The importance and value of the
BAROMETER to the farmer and out-door mechanic have
been long and fully acknowledged. Foretelling with the
utmost a 'curacy every impending change in the weather,
from twelve to thirty six hours in advance, by its use,
hay, grain, and other valuable crops, may be secured un-
injured, when otherwise much damage and loss might
ensue from exposure to storms. Then, too, in busy sea-
sons, much valuable time may be saved by their use.
Many times, in cloudy, foggy mornings, in the haying
and harvest season, the farmer is at a loss to decide
whether to cut down valuable hay or grain crops, and
much time is wasted waiting for the certainty of fair
weather, when the BAROMETER would instantly and un-
erringly decide the case. Operating upon infallible natu-
ral principles, no change in the weather can occur, how-
ever minute, but it is at once plainly indicated by this in-
strument. The great obstacle in the way of their general
use has been that its peculiar delicacy of construction
rendered it very liable to injury in transportation, and
formerly it had to be made where it was to be used, thus
involving great expense. Vast sums have been expended
in experiments to render the Barometer portable, but
until recently without success. Finally, in 1860, Mr.
Woodruff succeeded, after several years spent in experi-
menting, in perfecting this BAROMETER, in which porta-
bility, accuracy, durability, and siniplicity are perfectly
co:nbined. By simply turning a screw, the mercury is
so perfectly confined as to prevent the smallest motion
during transportation, and it can be as readily carried by
express or freight, as any ordinary glass ware. Its sim-
plicity renders it impossible to get out of order by ordi.
nary use, while the only materials coming in contact with
the mercury are perfectly indestructible, so that it is du-
rable for centuries. Its perfect accuracy is vouched for by,
the -- American Agriculturist,” or Country Gentleman,
“ Scientific Americain," and the agricultural and scientific
press universally, as well as by the many thousands of

scientific men, farmers, builders, masons, brick-moulders, gardeners, and others, who have them in practical use. Having secured the entire interest of the patentee in this invention, we are carrying on the manufacture extensively, and by the use of the best materials, careful and skilsul workinen, and superior facilities for manufacturing, we are enabled to produce an instrument perfectly portable, nicely aseurate, put up in beautiful walnut, oak, cherry, mahogany, or rosewood cases, at a price much lower than any reliable Barometer has ever been sold. We invite a triil of them by every prudent, intelligent farmer, confident that it will repay its cost by a few months' use. Single instances have often occurred where it has been worth many times its cost. Practical sci entific men estimate that a saving of five per cent. on tiie total value of the crops of the country, might be made by the general use of BAROMETERS, to indiente approaching storms, thus saving over fifiy million doilars annually. Aside from its real practical value, it furnishes an interesting and instructive study for schools and families. Chillien le:irn habits of observation, and form a taste for the study of the ever-varying phenomena of nature, from its use. Simply as an article of ornamental household furniture, it is well worth its price, which varies from nine to thirty dollars, according to finish.

God hath bech very good; 'tis he whose hand
Moulded the sunny hills, and hollowed out
The shelter of the valleys, and doth keep
The fountains in their secret places cool.
It is he who leadeth up the sun,
And ordereth the starry influences.
