dfy, they are slipped in a solution Of pasafan.
dissolved in photogens volatile oil. and Then
again dried. They are then dipped BY

New ARxr APpARArus.-church towers
were freely used by the Germans for recon-
noitinng during the war in France. but II
has been left to the ingenuity Of q Dane
Mr.. SAhlstrom Of Jonkoping-to construct a
special apparatus for the purpose. which
cAn be used where there are no natural or
artificial elevations accessible. It consists
Of q light ~expansible iron framework. sur
mounted by q cage capable Of holding thro:
persons, and mounted on O four-wheel car
riage. The apparatus shuts down on the
carriage, which is then about SIX feet in
height. The observers cage can be e!eva-
ted by two men in less han hvo minutes.
It a~ttains. when elevated. the height Of
from 75 to 80 feet. The weight Of the
whole is about 20 cwt.
