made from calcium carbide. In 1909
the consumption of the latter was
1850 tons.
The power generated in a modern
steamship in a single voyage across
the Atlantic is more than enough to
raise from the Nile and set in place
every stone of one of the great Egyp-

Aluminium is difficult metal to
tool, as it clogs the cutter. 1t also
shows tendency to split and check
on bending. Some of its alloys, as
that with magnesium and called
'magnalium," are said to be easily
workable.
A new type of submarine torpedo
boat is undergoing tests in England.
The boat is only "a feet long by 6 feet
D inches in diameter, and can be car
ried on the deck of a battleship, and
launched when it is desired to bring
it into action. 1t has a speed. when
submerged, of eight knots, carries two

One cubic foot of dry air at ordi-
nary temperature and pressure weighs
about .O74 h., or LIS OF. Some of the
high efficiency fans throw over 1885,.
700 cubic feet of air minute. This
means a volume equal to a cube over
o9 feet on a side, and an actual
weight of more than ~ tons. The
weight Is not striking, but the vol
ume required to gather this. together
with the friction and the heat of
compression all comprise a mechan-
ical condensation of great slgnifi-
canoe.
Reflected solar heat is used to OBJ

OF more than 5000 mirrors arranged

Geographers representing the prin-
cipal nations are at work upon man
of the entire earth on a scale of l to
l,OOO,OOO, and Professor Penck. the
German geographer, reports that Ga
sheets out of 437 planned had been
completed up to March last. On this
map the United States will cover an
area nearly 16 feet long. A distance.
OF one mile will be represented bv a
space about one-sixteenth of an inch
long There are, of course MANY
maps of small areas on a much larger
scale than this, but to represent the
whole face of the known world On
this scale Is an undertaking of much
interest.
Ihe 5O-ton steel car has now been
In use about eight years and it would
appear that 80 tons are the limit of
capacity. This is not likely to be in

special purposes in a narrow territory
Ihere are two principal reasons for

Seley In recent address at Purdua
University. The first is because tba

reason is that castiron wheels have
