I determined upon respectfully suggesting to your excellency the expediency of a topographical, geological, mineralogical and oryctological survey of Virginia. Should the enlightened representatives of the freemen of your state concur in this opinion, it will redound to the honor of all concerned, by the encouragement it will give to the study of the natural sciences--by the enhancement in value of lands in the interior, thereby enriching the state and its citizens, and giving a very proper check to unnatural migrations to the extreme west, by bringing to light and usefulness innumerable valuable crude materials, thereby not only enlarging the field of manufactures and the useful arts, but furnishing carrying for the canals and roads already constructed, and assisting in new internal improvements in locations of equal importance. That I may not appear to be too enthusiastic, pardon me for pointing out some of the most obvious features in the geology of Virginia. Whether we consider the comfort and convenience of our species, or the industry and prosperity of a state, there is no mineral production that can outvie in importance that of _coal_. In this country, where we have hitherto always had a superabundance of fuel, owing to the vast extent of our natural forests, the importance of a constant and abundant supply is not felt, and we are too apt to neglect properly to appreciate its value, but it is not so elsewhere, and a moment's reflection will shew that it ought not to be so _here_. Without fuel, of what use would be to us the metallic ores? for instance iron, which is now moulded, drawn and worked into thousands and tens of thousands of useful instruments, from a knife, to the complicated machinery of a steam engine, would forever remain an indissoluble and useless mass of matter without the aid of fuel--even the steam engine itself, that colossus of modern machinery, without the assistance of fire would be inactive and impotent. The Rev. Mr. Conybeare, an eminent English geologist, speaking of the coal veins (or coal measures, as they are there called,) of his country, thus expresses himself:
