Pàgina 16 - It can engrave a seal, and crush masses of obdurate metal like wax before it — draw out, without breaking, a thread as fine as gossamer, and lift a ship of war like a bauble in the air. It can embroider muslin, and forge anchors, cut steel into ribands, and impel loaded vessels against the fury of the winds and waves.
Pàgina 268 - There is a principle in human society, by which population is perpetually kept down to the level of the means of subsistence.

Pàgina 321 - Sufficient evidence has been adduced to convince your committee — 1. That carriages can be propelled by steam on common roads at an average rate of ten miles per hour. 2. That at this rate they have conveyed upwards of fourteen passengers.
Pàgina 276 - Carriages could ultimately be brought to such perfection as entirely to supersede draught horses on the common roads, there would be food and demand for eight millions of persons. But when we take further into consideration, that lowering the expense of carriage would enable us to extend cultivation over soils which cannot now be profitably tilled, and would have the further effect of enabling us to apply, with a profit, additional portions of labour and capital to the soils already under tillage,...

Pàgina 311 - M'Neil, shewing the greater efficiency with diminished expenditure of fuel by locomotive engines on railways, convinces the Committee that experience will soon teach a better construction of the engines, and a less costly mode of generating the requisite supply of steam.

Pàgina 320 - As speed, therefore, is the cause of greatly increased expense where horses are used, while with steam it is comparatively unimportant, it is probable that the latter will be chiefly resorted to when rapidity of conveyance is required. Mr. Gurney considers, that, under four miles per hour, horses can be used in draught more economically than steam. Should it, however, be deemed profitable to convey heavy goods by steam carriages, the committee recommend that there should be as little interference...
