Страница 268 - I have seen a small manufactory of this kind where ten men only were employed, and where some of them consequently performed two or three distinct operations. But though they were very poor, and therefore but indifferently accommodated with the necessary machinery, they could, when they exerted themselves, make among them about twelve pounds of pins in a day.
Страница 75 - These are thy glorious works, Parent of good, Almighty, thine this universal frame, Thus wondrous fair; thyself how wondrous then ! Unspeakable, who sitt'st above these heavens, To us invisible, or dimly seen In these thy lowest works; yet these declare Thy goodness beyond thought, and power divine.
Страница 269 - But if they had all wrought separately and independently and without any of them having been educated to this peculiar business, they certainly could not each of them have made twenty, perhaps not one pin in a day...

Страница 266 - But this proportion must in every nation be regulated by two different circumstances : first, by the skill, dexterity, and judgment with which its labour is generally applied ; and, secondly, by the proportion between the number of those who are employed in useful labour, and that of those who are not so employed.
Страница 269 - The great increase in the quantity of work, which, in consequence of the division of labour, the same number of people are capable of performing, is owing to three different circumstances: first, to the increase of dexterity in every particular workman; secondly, to the saving of time, which is commonly lost in passing from one species of work to another; and, lastly, to the invention of a great number of machines which facilitate and abridge labour, and enable one man to do the work of many.
Страница 270 - A man commonly saunters a little in turning his hand from one sort of employment to another. When he first begins the new work, he is seldom very keen and hearty; his mind, as they say, does not go to it, and for some time he rather trifles than applies to good purpose.
