Gave evidence Of the progress OF his
experiment. In minute the board
was bursting out in flames. The
focus was then shifted upon the
zine. In 3 few moments it began to
turn color; then shrink rs il anx-
ious to get away whercAit was cool
er, and then in less thanthrec mini
utes the entire surface covered by
the focus was literally melting, drop |
by drop. TO melt zinc requires n
temperature of over 700 degrees
Fahrenheit. The more wonderful
feature about the whole thing is the
brilliancy of the light. Each mirror
adds not only heat but light. The
forty mirrors produced a light more
brilliant than any ordinary electric
light. A hand, held SO as to inter
cept this focus, becomes as white as
driven snow A white handkerchief
defies ordinary sight, and conveys
but an impression OF beautiful white
ness. 1t is as hard to look at as
the sun itself The possibilities OF
Mr.. Calvers invention are bound
less. With a combined square sur
face of twenty feet of mirrors, lead
melts quicker than thought, wood
bursts into flame and is gone into
ashes, and iron melts in less than
twenty minutes. Each mirror adds
so much to the heat and light, and
Mr.. Calver has found by actual ex-
pertinent that comparatively small
collection of mirrors, each one foot
square, will
MELT ALL KNOWN METALS
In very few moments. He has
produced over 1000 degrees Of heat
with his mirrors By calculation it
is shown that 1000 mirrors, each a
foot square, will melt iron and steel
with the rapidity almost OF thought
There are processes, too, by which
even this enormous quantity Of heat
can be condensed and made to per-
form incredible feats. A concaye
mirror planed at tho 4naaaa af thu
large mirror will throw a pin point
of heat back toward the mirrors,
b )uid their numbers be increased
by several thousand, capable of cat
ing through solid mass of steel ten
feet thick, like flash, and US easily
as needle goes through u cheese.
The immense practical value of the
1 invention can be readily understood.
Mr.. Calver's forty mirrors boils
water in less than no time. An ege
i placed in the water is done hard
quicker than by fire. Meat and
vegetables are cooked in ten OF
fifteen minutes. A half hours sun
shine any time between 9. A. NJ. ane

cooking for an ordinarily y-sized fam
lily for week, If necessary. BY tht
mirrors engines can be run, well;
dug, mines worked, ore melted anC
refined, every kind of cooking per
formed; and, in short, there is NJ
variety Of industry in which they
cannot successfully compete Will
