A striking example of scientific
forestry is furnished by the coast of
France, chiefly Gascony, where in
1893 tree planting was begun in au
attempt to fix the sand dunes, which
the winds we're steadily pushing in
land over the vineyards. Pine forests
have now covered 275, 900 of the $50,
700 acres of dunes. bout 81, ,000, 600
has been spent on the work with
500, 600 more for forest adminstra
tion, but the State has received $40, =
600 more than the cost. while the
125, 900 acres still retained have a
value of $40, 900, 600. Farther inland,
about 1000, 900 acres of worthless
shifting sands and marshes, in the
triangular area of the Landes, have
been coverted into profitable pine
forest since the middle of last CEN
tury. This work, mostly done by the
commUnes, has created a property
worth 500, 900, 900 as valued from the
present yield of pine timber and
resin.

1t practicable to burn low grades of
slack coal In western Pennsylvania,
and now it is being found in Eng
land that little oil gas not only
imparts high efficiency to poor coal
but gives a fire without smoke. In
jected by let of steam into a retort
at the front of the furnace, the oil is
gasified by being passed to the rear of
the fire and back to the retort befure
being blown down 1pon the fire. AS
small proportion as 3 per cent of
oil greatly increases the heating
value of bituminous coal and makes
it smokeless; while cheap inferior

A. Magelssen, a German physician,
now reports that even epidemic
diseases are connected with atmos-
pheric conditions. Records at Chris
tiania since 1860 show that scarlet
fever, for instance, huctuates with
changes in temperature and weather.
The sick man gauges his illness by
the amount of his pain, his fever,
and his loss of appetite, looking upon
the last as of greatest significance.
Attempting an experimental analysis
OF appetite, DR.. j. Strickland Good
all, of London finds that craving for
food is of two general kinds-a primi-
tive hunger, depending upon tissue
growth, and psychic hunger. due to
cerebral or nervous action. The first
is the hunger of the new born.
Psychic hunger develops with the
sense organs, Is absent at BIRTH at a
minimum in the young, and becomes
of maximum Importance in the
advanced liver or epicure, but
Is the result of sense evolution and
education. The experiments prove
that psychic hunger is based largely
upon individual likes and dislikes,
, but greatlyssm odiIied by early educa-
tion and needs. A kitten, for In
stance, can be taught to prefer toma-
toes to fish. This hunger is totally
absent in the new born animal, which
has no likes or dislikes, and the
new born infant sucks its finger as
readily after dipping in castor oil
as when wet with milk. Vision,
t0sto and smell have important but
variable influence, Vision is lead
lug factor in psychic appetite in
birds, some fishes, and monkeys;
smell, in dogs; and taste, in adult
man. Cats depending on vision, eat
lead lotion moro readily than milk
from blue saucer, and refuse
green stained milk but greedily
devuur red-staiued. Fishes, when
blinded, starve in the midst of
plenty. Vision is of some import,
