Seite 124 - Not only the wealth but the independence and security of a country appear to be materially connected with the prosperity of manufactures. Every nation, with a view to those great objects, ought to endeavor to possess within itself, all the essentials of national supply.
Seite 121 - It is worthy of particular remark that, in general, women and children are rendered more useful, and the latter more early useful, by manufacturing establishments, than they would otherwise be.
Seite 121 - The spirit of enterprise, useful and prolific as it is, must necessarily be contracted or expanded in proportion to the simplicity or variety of the occupations and productions which are to be found in a society. It must be less in a nation of mere cultivators than in a nation of cultivators and merchants; less in a nation of cultivators and merchants than in a nation of cultivators, artificers, and merchants.

Seite 47 - ORDER Let all your things have their places; let each part of your business have its time. 4 RESOLUTION Resolve to perform what you ought; perform without fail what you resolve. 5 FRUGALITY Make no expense but to do good to others or yourself; ie, waste nothing. 6 INDUSTRY Lose no time; be always employed in something useful; cut off all unnecessary actions.
Seite 32 - Punctuality gives weight to character. "Such a man has made an appointment: then I know he will keep it.
Seite 122 - Where a nation imposes high duties on our productions, or prohibits them altogether, it may be proper for us to do the same by theirs...
Seite 123 - If the system of perfect liberty to industry and commerce were the prevailing system of nations, the arguments which dissuade a country, in the predicament of the United States, from the zealous pursuit of manufactures, would doubtless have great force. It will not be affirmed that they might not be permitted, with few exceptions, to serve as a rule of national conduct. In such a state of things, each country would have the full benefit of its peculiar advantages to compensate for its deficiencies...
Seite 123 - When a domestic manufacture has attained to perfection, and has engaged in the prosecution of it a competent number of persons, it invariably becomes cheaper. Being free from the heavy charges which attend the importation of foreign commodities, it can be afforded, and accordingly seldom or never fails to be sold cheaper, in process of time, than was the foreign article for which it is a substitute.
