extensive use for various purposes, one
Of its principal applications being the
compression of steel castings. In Berlin
the FIRE engines are each supplied with a
large vessel containing the condensed gas,
which is allowed to flow into the engines

From results obtained with variou.
fcr.ilizing substances Prof. Atwater has
drawn the following conclusions: Corn
Aeeds little nitrogen besides what it can
draw from natural sources, while its yield
il largely increased under the influence
of mineral fcrtilizers--the most effective
being those in which the chief componcn,
b phosphoric acid or potash, according t,
the soil and the season. Potatoes responc
uniformity to all the fertilizing ingredi
ents; and they are less able than corn t,
gather from natural sources The sam,
appears to be true of turnips. Not enough
experiments have been made with othe,
crops 10 justify conclusions concerning
them. Practically the largest averag,
yield for all crops is secured by the ust
Of fertilizers containing all the essential
elements Of plant food Used alone, nj.
trate of soda is rarely useful, sulphatc of
lime frequently, muriate of potash very
often, and the supaphosphates generally
Soils vary in their capacity for conveying
food to crops, and careful observation and
experiment are necessary to determine the
needs of particular soil.

The usual method Of determining the
temperature OF room by thermometer
hung upon the wall gives very uncertain
results, as Mons. Castor Tissandier has
shown that rooms apparent temperature
may vary many degrees according to the
position of the Thermometer The upper
part OF a room is much warmer than the
lower, and windows and doors have
very marked effect upon the temperature
Of the air in their vicinity. As means
OF accurately obtaining the temperature,
Mons. Tissandicr suggests that the Their.
nometer be held at the hight of man
tor about two minutes at several different
points, the average of these observations
70 be taken as the real temperature.
