The motive power of the British manufacturer is derived from coal, of which he has an unlimited supply: the motive power of the British farmer is, except to a very small extent, dependent upon animals, which is infinitely more expensive and tedious; requiring more work with less command of power. The manufacturer can try any experiment he pleases, either in the construction of his machinery or in the texture of his fabric, in the course of a few days or weeks, and adopt or reject it as best suits his purpose: the farmer cannot attempt any experiment upon his crops without waiting a whole year for the result; nor any upon his live stock in less than two or three years. In the mean time, his expenses and rent go on as usual. The British manufacturer is not dependent on the climate: the British farmer is altogether so dependent; the climate of this country being proverbially uncertain and changeable, and very often ungenial. We apprehend, therefore, that, as to natural advantages, the home manufacturer stands on a far more advantageous footing than the home agriculturist. Let us next contrast the state of the two classes abroad. The foreign manufacturer has few natural advantages. He does not possess the command of coal for his motive power, but is compelled to erect his factory on the bank of some stream, without regard, otherwise, to the convenience of the locality. Iron for machinery is far more expensive abroad than here; in fact, most of the Continental machinery is directly exported from Britain. On the other hand, the foreign farmer has all the advantages of an equable, rich soil, and of a good and steady climate.
