76. A reservoir of water has two pipes to supply it. The first
would fill it in 40 minutes, and the second in 50. It has likewise

minutes. Now, if all the pipes are opened at once, and the water
runs uniformly as we have supposed, how long before the cistern
will be filled?

77. A traveller leaves New Haven at 8 o'clock on Monday

miles an hour ; now, supposing the distance to be 130 miles,
where on the road will they meet ?

315. A triangle is a portion of a plane
bounded by three straight lines. BC is
called the base ; and AD, perpendicular to

to the product of half its base by its altitude
(Bk. IV. Prop. VI).*

323. A circle is a portion of a plane
bounded by a curved line, called the circum-
ference. Every point of the circumference is
equally distant from a certain point within
called the centre : thus, C is the centre, and
any line, as ACB, passing through the centre,
is called a diameter.

If the diameter of a circle' is 1, the circumference will be
3.1416. Hence, if we know the diameter, ^ce may find the circum-
ference by multiplying by 3.1416 ; or, if we know the circumference.,
we may find the diameter by dividing by 3.1416.

338. The mean diameter of a cask is found by adding to tho
head diameter, two thirds of the difference between the bung and
head diameters, or if the staves are not much curved, by adding"
six-tenths. This reduces the cask to a cylinder. Then, to find
the solidity, we multiply the square of the mean diameter by the
decimal .7854 and the product by the length. This will give
the solid contents in cubic inches. Then, if we divide by 231,
we have the contents in gallons. (Art. 114).

Multiply the length by the square of the OPERATION.

and divide by 231. ' J x d 2 x .0034.

If, then, we divide the decimal ,7854 by 231, the quotient car-
ried to four places of decimals is .0034, and this decimal multi-
plied by the square of the mean diameter and by the length of the
cask, will give the contents in gallons.

339. Hence, for gauging or measuring casks, we have the fol.

NOTES.

1. A NOTE, or as it is generally called, a promissory note, is a
positive engagement, in writing, to pay a given sum at a time
specified, either to a person named in the note, or to his order, or
to the bearer.

2. By mercantile usage a note does not really fall due until the
expiration of 3 days after the time mentioned on its face. The
three additional days are called days of grace.

APPENDIX. 311

When the last day of grace happens to be Sunday, or a holiday,
such as New Years, or the Fourth of July, the note must be paid
the day before : that is, on the second day of grace.

3. There are two kinds of notes discounted at banks : 1st. Notes
given by one individual to another for property actually sold
for the purpose of borrowing money, which are called accommo-
dation notes, or accommodation paper. Notes of the first class are
much preferred by the banks, as more likely to be paid when they
fall due, or in mercantile phrase, " when they come to maturity."

312 APPENDIX.

REMARKS RELATING TO NOTES.

1. The person who signs a note, is called the drawer or maker
of the note ; thus, Reuben Holmes is the drawer of Note No. 1.

2. The person who has the rightful possession of a note, is
called the holder of the note.

3. A note is said to be negotiable when it is made payable to
A B, or order, who is called the payee (see No. 1). Now, if Abel
Bond, to whom this note is made payable, writes his name on the
back of it, he is said to endorse the note, and he is called the en-
dorser ; and when the note becomes due, the holder must first
demand payment of the maker, Reuben Holmes, and if he declines
paying it, the holder may then require payment of Abel Bond, the
endorser.

4 If the note is made payable to A B, or bearer, then the
drawer alone is responsible, and he must pay to any person who
holds the note.

5. The time at which a note is to be paid should always be
named, but if no time is specified, the drawer must pay when re-
quired to do so, and the note will draw interest after the payment
is demanded.

6. When a note, payable at a future day, becomes due, and is
not paid, it will draw interest, though no mention is made of inter-
est.

7. In each of the States there is a rate of interest established by
law, which is called the legal interest, and when no rate is speci-
fied, the note will always draw legal interest. If a rate higher
than legal interest be taken, the drawer, in most of the States, is
not bound to pay the note.

8. In the State of New York, although the legal interest is 7
per cent, yet the banks are not allowed to charge over G per cent,
unless the notes have over 63 days to run.

9. If two persons jointly and severally give their note, (see No.
3,) it may be collected of either of them.

10. The words "For value received" should bo expressed in
every note.

11. When a note is given, payable on a fixed day, and in a spe-
cific article, as in wheat or rye, payment must be offered at the
specified time, and if it is not, the holder can demand the value in
money.

A BOND FOR ONE PERSON, WITH A CONDITION.

BOOK-KEEPING.

PERSONS transacting business find it necessary to wiite down
the articles bought or sold, together with their prices and the
names of the persons to whom sold.

BOOK-KEEPING is the method of recording such transactions in a
regular manner.

COMMON ACCOUNT BOOK.

The following is a very convenient form for book-keeping, and
requires but a single book. l"c is probably the best form of a com-
mon Account Book.
