POINTS TO ADVERTISERS.

Nothing is sold without pushing, unless it has a monopoly.
No two articles can be pushed in exactly the same way.
In advertising you want to reach possible _customers_, not merely
people.
The best mediums for one line of goods may be the worst for another.
Advertising should not be visionary, it should not be attended to as a
mere pastime.
Success means thought, the day of chance successes is nearly over.
It costs no more to publish good matter than it does poor.
The preparation of an advertisement is as important as the publishing.
An advertiser needs an agent, as a client does a lawyer.
The agent, however, asks no retainer and saves his customer money.
A merchant cannot study advertising all the time--a good agent studies
nothing else.
The customer's interests are the agent's. If the agent is to succeed,
the business done must be successful.
The undersigned want business, but not badly enough to handle what is
"questionable."
They are honest and capable, their customers say, and they give close
personal attention to their business.

Though this work nominally treats of the trees and shrubs of
Massachusetts, it is equally applicable to the flora of many other
States; indeed all New England and a greater part of the Middle
States. In it is described every important tree or shrub that grows
naturally in Massachusetts, and in other States of the same latitude,
the descriptions being the result of careful personal observation.
It is, indeed, a comprehensive and convenient manual for almost every
section of t
