"A DOLLAR SAVED, A DOLLAR EARNED."

The way to accumulate money is to save small sums with regularity. A
small sum saved daily for fifty years will grow at the following rate:

Daily Savings. Result. Daily Savings. Result.
One cent $ 950 Sixty cents $ 57,024
Ten cents 9,504 Seventy cents 66,528
Twenty cents 19,006 Eighty cents 76,032
Thirty cents 28,512 Ninety cents 85,537
Forty cents 38,015 One dollar 475,208
Fifty cents 47,520

[Transcriber's note: The figures from 1 to 90 cents assume about 5.5%
interest. The one dollar amount ($475,208) assumes about 10% interest.]

At 4 per cent, by 90 At 10 per cent, by 36
At 5 per cent, by 72 At 12 per cent, by 30
At 6 per cent, by 60 At 15 per cent, by 24
At 7 per cent, by 52 At 20 per cent, by 18

TRADE DISCOUNTS.

Wholesale houses usually invoice their goods to retailers at "list"
prices. List prices were once upon a time supposed to be retail prices,
but of late a system of "long" list prices has come into vogue in many
lines of trade--that is, the list price is made exorbitantly high, so
that wholesalers can give enormous discounts. These discounts, whether
large or small, are called trade discounts, and are usually deducted at
a certain rate per cent from the face of invoice.

The amount of discount generally depends upon size of bill or terms of
settlement, or both. Sometimes two or more discounts are a
