PRACTICAL RULES FOR
EVERY DAY USE.
How to find the gain or loss per
cent. when the cost and selling price
are given.
RULE.-Find the difference between the
cost and selling price, which will be
the gain or loss.
Annex two ciphers to the gain or loss,
and divide it by the cost price; the
result will be the gain or loss per

of the gain or loss in a copartnership
business.
RULE.-Divide the whole gain or loss
by the entire stock, the quotient will
be the gain or loss per cent.
Multiply each partner's stock by this
per cent, the result will be each one's
share of the gain or loss.
How to find gross and net weight
and price of hogs.
A short and simple method for finding
the net weight, or price of hogs,
when the gross weight or price is given,
and vice versa.
NOTE.-It is generally
assumed that the gross weight of Hogs
diminished by 1-5 or 20 per cent. of
itself gives the net weight, and the
net weight increased by 1/4 or 25 per
cent. of itself equals the gross weight.
To find the net weight or gross price.
RULE.-Multiply the given number by .8
(tenths.)
To find the gross weight or net price.
RULE.-Divide the given number by .8
(tenths.)
How to find the capacity of a granary,
bin, or wagon-bed.
RULE.-Multiply (by short method) the
number of cubic feet by 6308, and point
off ONE decimal placethe result
will be the correct answer in bushels
and tenths of a bushel
For only an approximate answer, multiply
the cubic feet by 8, and point off one
decimal place.

RULE.-Multiply the number of cubic feet
by 54, short method, or by 41
253
ordinary method, and point off ONE
decimal place-the result will be the
answer in bushels.
NOTE.-In estimating corn
in the ear, the quality and the time
it has been cribbed must be taken into
consideration, since corn will shrink
considerably during the Winter and Spring.
This rule generally holds good for corn
measured at the time it is cribbed,
provided it is sound and clean.
How to find the contents of a cistern
or tank.
RULE.-Multiply the 'square of the mean
dip-meter by the depth (all in feet)
and this product by 5681 (short method),
and point off ONE decimal place-the
result will be the contents in barrels
of 3 1/2 gallons. .
How to find the contents of a barrel
or cask.
RULE.-Under the square of the mean diameter,
write the length (all in inches) in
REVERSED order, so that its UNITS will
fan under the TENS; multiply by short
method, and this product again by 430;
point off one decimal place, and the
result will be the answer in wine gallons.
How to measure boards.
RULE.-Multiply the length (in feet)
by the width (in inches) and divide
the product by 12-the result will be
the contents in square feet.
How to measure scantlings, joists,
planks, sills, etc.
RULE.-Multiply the width,
the thickness, and the length tog-ether
(the width and thickness in inches,
and the length in feet), and divide
the product by 12-the result will be
square feet.
How to find the number of acres in
a body of land.
RULE.-Multiply the length by the width
(in rods), and divide the product by
160 (carrying the division to2 decimal
places if there is a remainder); the
result will be the answer in acres and
hundredths.

land are of unequal length, add them
together and take one-half for the mean
length or width.

yards in a floor or wall.
RULE.-Multiply the length by the width
or height (in feet), and divide the
product by 9, the result will be square
yards.
How to find the number of bricks
required in a building.
RULE.-Multiply the number of cubic feet
by 22 1/2.
The number of cubic feet is found by
multiplying the length, height and thickness
(in feet) together.
Bricks are usually made 8 inches long,
4 inches wide, and two inches thick;
hence, it requires 27 bricks to make
a cubic foot without mortar, but it
is generally assumed that the mortar
fills 1-6 of the space.
How to find the number of shingles
required in a roof.
RULE.-.Multiply the number of square
feet in the roof by 8, if the shingles
are exposed 4 1/2 inches, or by 7 1-5
if exposed 5 inches.
To find the number of square feet, multiply
the length of the roof by twice the
length of the rafters.
To find the length of the rafters, at
ONE-FOURTH pitch, multiply the width
of the building by .56 (hundredths);
at ONE-THIRD pitch, by .6 (tenths);
at TWO-FIFTHS pitch, by .64 (hundredths);
at ONE-HALF pitch, by, 71 (hundredths),
This gives the length of the rafters
from the apex to the end of the wall,
and whatever they are to project must
be taken into consideration.
NOTE.-By 1/4 or 1/3 pitch
is meant that the apex or comb of the
roof is to be 1/4 or 1/3 the width of
the building higher than the walls or
base of the rafters.
254
How to reckon the cost if hay.
RULE.-Multiply the number of pounds
by half the price per ton, and remove
the decimal point three places to the
left,
How to measure grain,
RULE.-Level the grain; ascertain the
space it occupies in cubic feet; multiply
the number of cubic feet by 8, and point
off one place to the left.
NOTE.-Exactness requires
the addition to every three hundred
bushels of one extra bushel.
The foregoing rule way be used for finding
the number of gallons, by multiplying
the number of bushels by 8,
If the corn in the box is in the ear,
divide the answer by 2, to find the
number of bushels of she1led corn, because
it requires 2 bushels of ear corn to
make 1 of shelled corn.
Rapid rules for measuring land without
instruments.
In measuring land, the first thing to
ascertain is the contents of any given
plot in square yards; then, given the
number of yards, find out the number
of rods and acres.
The most ancient and simplest measure
of distance is a step. Now, an ordinary-sized
man can train himself to cover one yard
at a stride, on the average, with sufficient
accuracy for ordinary purposes.
To make use of this means of measuring
distances, it is essential to walk in
a straight line; to do this, fix the
eye on two objects in a line straight
ahead, one comparatively near, the other
remote; and, in walking, keep these
objects constantly in line.
Farmers and others by adopting the following
simple and ingenious contrivance,, may
always carry with them the scale to
construct a correct yard measure.
Take a foot rule, and commencing at
the base of the little finger of the
left hand, mark the quarters of the
foot on the outer borders of the left
arm, pricking in the marks with indelible
ink.
To find how many rods in length will
make an acre, the width being given,
RULE,-Divide 160 by the width, and the
quotient will be the answer,
How to find the number of acres in
any plot of land, the number of rods
being given,
RULE.-Divide the number of rods by 8,
multiply the quotient by 5, and remove
the decimal point two places to the
left,
The diameter being given, to find
the circumference.
RULE.-.Multiply the diameter by 3 1-7.
How to find the diameter, when the
circumference is given,
RULE.-Divide the circumference by 3
1-7.
To find how many solid feet a round
stick of timber of the same thickness
throughout will contain when squared.
RULE.-Square half the diameter in inches,
multiply by 2, multiply by the length
in feet; and divide the product by 144.
General rule for measuring timber;
to find the solid contents in feet.
RULE.-Multiply the depth in inches by
the breadth in inches, and then multiply
by the length in feet, and divide by
144.
255
To find the number of feet of timber
in trees with, the bark on.
RULE.-Multiply the square or one-fifth
of the circumference in inches, by twice
the length, in feet, and divide by 144.
Deduct 1-10 to 1-15 according to the
thickness of the bark.
Howard' s new rule for computing
interest.
RULE.-The reciprocal of the rate is
the time for which the interest on any
sum of money will be shown by simply
removing the decimal point two places
to the left; for ten times that time,
remove the point one place to the left;
for 1-10 of the same time, remove the
point three places to the left. .
Increase or diminish the results
to suit the time given.
NOTE.-The reciprocal
of the rate is found by inverting the
rate; thus 3 per cent. per month, inverted,
becomes 1/3 of a month, or ten days.
When the rate is expressed by one figure,
always write it thus: 3-1, three ones.
Rule for converting English into American
currency.
Multiply the pounds, with the shilling's
and pence stated in decimals, by 400
plus the premium in fourths, and divide
the product by 90.

THE PIONEER.
In the heart of the grand old forest,
A thousand miles to the West,
Where a stream gushed out from the hill
side.
They halted at last for rest.
And the silence of ages listened
To the axe-stroke loud and clear,
Divining a kingly presence
In the tread of the pioneer.
He formed of the prostrate
beeches
A home that was strong and good;
The roof was of reeds from the streamlet,
The chimney he built of wood.
And there by the winter fireside,
While the flame up the chimney roared,
He spoke of the good time coming,
When plenty should crown their board
When the forest should
fade like a vision,
And over the hill-side and plain
The 9rchard would spring in its beauty,
And the fields of golden grain.
And to-night he sits by the fireside
In a mansion quaint and old,
With his children's children around
him,
Having reaped a thousand fold.
