Noble and swelling sentiments! but such as cannot be reduced into practice. Grand ideas! but which must be qualified and adjusted by a compromise between the aspirings of individuals, and a due concern for the general tranquility; must be subdued and chastened by reason and experience before they can be directed to any useful end! A search after abstract perfection in government may produce in generous minds an enterprise and enthusiasm to be recorded by the historian and to be celebrated by the poet; but such perfection is not an object of reasonable pursuit, because it is not one of possible attainment; and never yet did a passionate struggle after an absolutely unattainable object fail to be productive of misery to an individual, of madness and confusion to a people. As the inhabitants of those burning climates which lie beneath a tropical sun sigh for the coolness of the mountain and the grove, so (all history instructs us) do nations which have basked for a time in the torrid blaze of unmitigated liberty too often call upon the shades of despotism, even of military despotism, to cover them--a protection which blights while it shelters; which dwarfs the intellect and stunts the energies of man, but to which a wearied nation willingly resorts from intolerable heats and from perpetual danger of convulsion. Our lot is happily cast in the temperate zone of freedom, the clime best suited to the development of the moral qualities of the human race, to the cultivation of their faculties, and to the security as well as the improvement of their virtues; a clime, not exempt, indeed, from variations of the elements, but variations which purify while they agitate the atmosphere that we breathe. Let us be sensible of the advantages which it is our happiness to enjoy. Let us guard with pious gratitude the flame of genuine liberty, that fire from heaven, of which our Constitution is the holy depository; and let us not, for the chance of rendering it more intense and more radiant, impair its purity or hazard its extinction.

The canal companies had employed able counsel to oppose it. A month was consumed before the company's engineer, Mr. George Stephenson, was called by the Committee. The following account of his first day's examination is from his fascinating biography by Dr. Samuel Smiles.]
