@. Where does EPSON salt come
from?-E. w. b.
A. EPSON salt was originally OBJ
tanned from waters Of the mineral
spring in Epson. England, and subse-
quently was made by decomposinc
dolomite with sulphuric acid; but the
| principal source of the commercial
salt is now the Stassfurt salt mines
| in Saxony, where the crude mineral is
| separated from the accompanying
| magnesium and sodium chlorides by
| dissolving out these two salts with
water. which leaves the magnesium
sulphate as fine powder that may be

| @. How slowly can an airplane
| travel?-J. y. J.
| a. The lowest rate of speed AT
| which an airplane can travel and

/ DOlllI oLoIAiLAS pOAiiI -
at the point where the air lift on the
| wings is less than the weight Of the
airplane, practically little above TAX
ing off speed. which is 40 to so miles
per hour.
| O. Why does u safety match ignite
when scratched on a glass window
| panel. W.
A. The Bureau of Standards says
probably because the very smooth and
hard surface of the glass makes the
point of contact of the match head
small and the friction is all at this
small point. This causes the match
composition to be heated to its igni-
tion point. On a rougher surface the
match head is worn off. If the sur
face is softer than the glass the head
sinks into it enough to increase the
area of contact, and thus the heating
effect is distributed over too large d
SURFACE for the temperature at any
point to become high enough TO ig
mite the composition. To light the
match on glass requires a quick.
sweeping stroke with firm pressure.
