A new process for drying fruit and
egetables-already in use for drying
consists in drawing air through
gridwork Of steam pipes into cham
Der below the slotted floor holding the
materials to be dried. Absorption Of
sulphurous gases is avoided, while
burning Is impossible. In test at
Worcester. England, samples Of ear
rots, potatoes, sliced and shredded ap-
pies, and other fruits and vegetables,
were kept at temperatures Of 20 to
100 degrees for six hours, reaching the
ordinary commercial state Of dryness.
The cost of working being small, 1t is
expected that an important new Indus
try will soon develop in England.
The curious phenomena Of "symphil-
ism" are being investigated by e.
Wasmann, a German zoologist This
Is the harboring of foreign species Of
insects, etc., in the nests Of ants and
termites, and it is found that more
than one hundred species Of arthro-
pods, or creatures with jointed legs,
are thus associated with the ants, at
least, eighty-flve or ninety species be-
Ing beetles. All are recognized easily
BY certain peculiarities. Most notable
among the characteristics of these bee
ties are their oily reddish-yeilow or
reddish-brown color, and special exu.
dalton organs or pores with brownlsh
hairs. but there are also notifications
Of the mouth and other parts.
