Every bee has, two kinds of eyes;
the two large, compound ones, looking
like hemispheres on either side, and

an immense aggregation Of eyes, each
being composed of $500 facets, which
means that every object seen has it's
image reflected $500 times in the bees

F An industry which promises, it
seems. to greatly increase in the near
future has been started in Arizona and
New Mexico. Some years ago the dis
covery was made that the root OF
eanaigre, plant which grew wild in
the woods of New Mexico and Arizona,
could be used to advantage in tanning
| leather. Hundreds of tons Of this root
We're dug and sold. The fact soon be
came evident that the supply Of
canaigre was nearly exhausted. The
plan of cultivating the plant was then
taken up by the farmers Of that Sec
ton. This crop has proved success,
and now we hear that many farm
ers are planting from 1000 to 1900
acres Of canaigre: In the Pecos val
ley a factory for making tanning
extract from the root is being erected.
The yield is from 10 to Is tons to the
acre, and this roots bring the farmers
