II this question were put to you: WI,
do we need two eyes?" you would Yer,
likely answer the query by saying, "Wh,
do we need two arms or two ears?" But
this is not the proper answer to the quss.
ton Two eyes mated are absolutely nee
rssar, 10 obtain perfect sight Perhaps
you have heard IL said that people having
one eye could see better than those With
two. Possibly that would seem so to pco-
pie who have observed the quickncss with
which one-cyed person perceived the
movement of objects. and the fact that
they DO not seem to miss anything tiiat
ing. the onc-eyed person has much to re-
gret, although he may be the only ono
conscious of his loss.
For example, a one-eyed man can not
readily hook his cane through n ring over
his head, for his one eye does not tell him
how far the ring is. and he has to feel
around for il until he finds it, A iuan
with two eyes does not have the slightest
difficulty For 1t is we'll estabishcd,
philosophical fact that for objects TO seem
solid we must have two ewes.
1 Another illustration as to the Importance
of having two perfect eyes for correctly
measuring distances will lie found inter-
esting. as well as amusing, as follows.
Place your hand tightly over one eye; take

the pencil quickly on II small object,
bringing YOU hand straight down from

plish this. providing you do not hesitate or
feel your way in trying TO reach the object
When we look at the world with only one
eye open, the whole scene appears to be

but to the eye all things appear to be
about on the same surface. The views
that reach the two eyes are slightly differ
ent, as any one can prove to himself by
opening and closing the eyes alternately.
This Is what makes us see the real world
as solid. Now, IL we want any picture to
appear as solid, We must see 1t from
slightly different points Of view. each eye
forming separate and distinct image,
which gives the round and full effect nee

relief.
The loss of an eye can not be compared
In any way to the loss OF an ear or /.
limb, for in this case certain THINGS can
be ACCOMPLISHED as well with one as with
two. But Ii the event of loss of an eye,
person is !or all time crippled And the
anxiety usually felt by person blind in
one eye TO preserve and care for the good
eve is something pathetic. And still we
can not wonder. for ii seems to be tho
general sentiment that people would rather
give up their lives than their sight And
II certainly stands people In hand who are
even conscious of the slightest difference

matter serious consideration. For slight
defects neglected often become serious be-

the children. for errors in their sight are
so much easier corrected in early life than
when they are neglected until maturity is
reached.
