The completion of this truly great military work must, in a great measure, depend upon the decrease of the subsidence to which the soil is liable, and for which it is necessary to pause after every year's addition of pressure, in order to proportion such a resistance as may restore the equilibrium and secure the foundation. When I was here, one of these pauses in the engineering department had place; but it was said, the President had intimated his design of passing the hot season upon this spot, when the works would be vigorously resumed under his inspection. Sailing up the Elizabeth river, so famous in the gallant Raleigh's story, we reached Norfolk at eight o'clock A.M., when a portion of our living freight was quickly transferred to the Virginia steamer for Charleston; another portion, to which I was attached, being, with similar promptitude, handed over to the Pocahontas ditto, bound for Richmond, the capital of Virginia. In less than an hour we were sailing back through the well-closed harbour of Norfolk; whence, crossing the Elizabeth river, we entered, in a couple of hours, the noble stream now rightly called, after its legitimate sovereign, the Powhatan, but better known as the James's river,--"a great sinking in the poetry of the thing," though Jamie also was a king, "but no more like his brother," &c. Upon the southern banks rise a constant series of fine bold bluffs, mostly crowned with forest trees of great beauty, now dressed in that rich-coloured foliage so often lauded by poet and painter, but as yet, I fancy, never done full justice to. Scott and Turner, those inspired illustrators of nature, might have done this: as it is, I hope America will, before many years are past, find, amongst her own sons, pens and pencils worthy to give her beauties to the admiration of the Old World. We arrived off the original city founded in the "Old Dominion," having some passengers to land upon the beach, now almost as wild as when first trodden by the adventurous foot of the bold Captain Smith. Within a few yards of the landing-place stood the first Christian church erected on this mighty continent: I grieve to add, this interesting altar to the true God no longer bears his holy word: a dilapidated, but sturdy-looking square tower of brick, alone remains to mark the site of church and city; indeed, without timely care is bestowed by some gentle, generous spirit, even this most interesting memorial will speedily disappear. At present this forms one of the very few objects to which the term picturesque may properly be applied, existing in the States; and, linked as it is with the recollections of its gallant founders, I confess it laid strong hold of my imagination, absorbing my eyes and interest as long as I could keep it in view.
