The Heat Of the Sun,

earth receives from the tun is 20 cnor.

quantity is stnrtli, & enough. seeing that
every 100 square Ect Of sun liz earth re
ceives an amount equivalent to tho work

Last Summer, 90 the tropical 22d Of
July, . steak and potatoes were thor.
oughly cooked by the sun on the south
side Of Westminster Bridge. The only
apparstus employed was q cigar box
blaca<encl inside, and With q lid formed
Of several preces Of glass. The solar
beams poured into this oven, and there
heat was trapped there was no ready es.
cape for it, and in 20 minutes from tho
time Of their drst expoSure the steak aud
potatoes were done.
Ercsson's name alone has been cited
az a solar engineer But there has been
another toiler in the same field, NJ.
Mouehot, French professor of natural
philosophy. The principle involved in the
cigar boz oven is that which he has
adapted to the construction Of that hc
calls solar receiver. A metallic vessel,
blackeDed ontside, is mounted on a non.
conducting pedestal aud covered with a
glass case it is exposed to the sun and
an extra amount Of heat is condensed
upon 1t by reflector placed beh,ud. In
less than half an hour, the vessel if
empty, is raised to tho temperature Of
4OOo Fair. Tho receiver may b. boiler
to generate steam, or a sauce. pan for Gu.
linary purposes, or the evaporator of q
still, or an oven for cooking steaks and
potatoes. A working steam engine was
among come solar apparatus which NJ.
