SQUARE is the 'smeasuring unit" The amount OF all
surface is determined by square This amount
may be expressed in miles, furongs, rods, yards feet
inches or any other specified measure No matter what
the shape of quantity OF land, boards, cloth, paper,
glass; or any other article the amount OF surface is al
ways asceaned and expressed by the number OF
and parts of squares it contains. either in miles feet or
some other known measure. The properties and Of
this most simple Of all figures, one, of course
important 10 be understood amarly by every per-
son. No one thing probably is at once so important
and so little understood the figure with four equal sides
and angles Very many OF the most intelligent members
Of society have clear apprehension OF the difference
between six miles square and six square miles per-
son of much intelligence commended few days ago thai
in the District Of Columbia, in its original dimensions,
there were only square miles, and could not be con-
WINGED of his error until shown it by checker board
Not long since a painter of twenty years expe-
renee named price per sheet for painting paper. On
being ask what would be his price Tor sheets OF double
the length and breadth, replied, double the price offer
ing of course to do four times the work for twice the
money CAses of . similar character might be named
almost without number Of intelligent experienced bus.
ness men making banders attended with far greater IN
convenience and loss than working half price, and
simply from the want OF little knowledge, entirely
within the comprehension of every child OF five years
old, attended with high degree Of pleasure in

Il children should occupy the first hour ever spent in
school room by drawing upon their states square with
s different divisions, they might have proof positive tina,
in an inch square four half Inch squares that IN ten
miles square there are hundred square miles They
would also proof positive that by the diagonal
division OF square, they would form two right angled
isoscees trianRIes or figures with right angle and
Two equal sides they would thus acquire at this early
age positive practical knowledge which would greatly
aid them in "squaring hsir soork" during The whole oil
their future lives. whatever might be their pursuits.
Those becoming editors would not be likely to make the
mistake OF one of the most able editors in the country,
Who in speaking of FIRE in Boston, stated that IT burnt
.bou, one hundred and fifty square feet; that Is, sur
lace equal 10 a room OF fifteen feet by ten II the space
burn, was one hundred and fifty feet square, contained
NOR. than twenty thousand square feetrather mistake
for an intelligent and able editor in the literary emporium
Of our Union
ErprsIMEsrs-I the schools OF New York and
Washington and OF all other places disposed should
have their attention directed for the few weeks before
he August holydays, to come practical lessons on the
properties and Of the square, they would doubtless
prepare many instructive and beautiful Illustrations in one
Of the most important branches OF knowledge, rendered
more instructive by exchanges between different schools
or being distributed through this and other countries for
the diffusion OF scientific light and the promotion of gen.
.rous and patriotic feelings National functonares both
Of our own and Of foreign governments, have in large
numbers expressed high degree OF pleasure in oppou
mites for distributing such knowledge for such purposes
Numerous such specimens of juvenile improvement, pre-
pared both in New York and Washington, have been
distributed far and vide in this and other countries
few deposited for distribution At the bookstore
Of Mr. Gray, in Seventh street, Warrington which Mr.
O. will be happy to show to those wishing TO examine
them.
