- "Your favor of the 7'th came duly to hand and the plant you are so good as to propose to send me will be thankfully rec'd. The little Mimosa Julibrisin you were so kind as to send me the last year is flourishing. I obtained from a gardener in this nbh'd [neighborhood] 2 plants of the paper mulberry; but the parent plant being male, we are to expect no fruit from them,unless your [trees] should chance to be of the sex wanted. at a future day, say two years hence I shall ask from you some seeds of the Mimosa Farnesiana or Nilotica, of which you were kind enough before to furnish me some. but the plants have been lost during my absence from home. I remember seeing in your greenhouse a plant of a couple of feet height in a pot the fragrance of which (from it's gummy bud if I recollect rightly) was peculiarly agreeable to me and you were so kind as to remark that it required only a greenhouse, and that you would furnish me one when I should be in a situation to preserve it. but it's name has entirely escaped me & I cannot suppose you can recollect or conjecture in your vast collection what particular plant this might be. I must acquiese therefore in a privation which my own defect of memory has produced, unless indeed I could some of these days make an impromptu visit to Phila. & recognise it myself at the Woodlands....
- "The grounds which I destine to improve in the style of the English gardens are in a form very difficult to be managed. They compose the northern quadrant of a mountain for about 2/3 of its height & then spread for the upper third over its whole crown. They contain about three hundred acres, washed at the foot for about a mile, by a river of the size of the Schuylkill. The hill is generally too steep for direct ascent, but we make level walks successively along it's side, which in it's upper part encircle the hill & intersect these again by others of easy ascent in various parts. They are chiefly still in their native woods, which are majestic, and very generally a close undergrowth, which I have not suffered to be touched, knowing how much easier it is to cut away than to fill up. The upper third is chiefly open, but to the South is covered with a dense thicket of Scotch (Spartium scoparium Lin.) which being favorably spread before the sun will admit of advantageous arrangement for winter enjoyment. You are sensible that this disposition of the ground takes from me the first beauty in gardening, the variety of hill & dale, & leaves me as an awkward substitute a few hanging hollows & ridges, this subject is so unique and at the same time refractory, that to make a disposition analogous to its character would require much more of the genius of the landscape painter & gardener than I pretend to. I had once hoped to get [[George Isham Parkyns|Parkins] to go and give me some outlines, but I was disappointed.... Should a journey at any time promise improvement to it [Hamilton's health], there is no one on which you would be received with more pleasure than at Monticello. Should I be there you will have an opportunity of indulging on a new field some of the taste which has made the Woodlands the only rival which I have known in America to what may be seen in England.
- "Thither without doubt we are to go for models in this art. Their sunless climate has permitted them to adopt what is certainly a beauty of the very first order in landscape. Their canvas is of open ground, variegated with clumps of trees distributed with taste. They need no more of wood than will serve to embrace a lawn or a glade. But under the beaming, constant and almost vertical sun of Virginia, shade is our Elysium. In the absence of this no beauty of the eye can be enjoyed. This organ must yield it's gratification to that of the other senses; without the hope of any equivalent to the beauty relinquished. The only substitute I have been able to imagine is this. Let your ground be covered with trees of the loftiest stature. Trim up their bodies as high as the constitution & form of the tree will bear, but so as that their tops shall still unite & yeild dense shade. A wood, so open below, will have nearly the appearance of open grounds. Then, when in the open ground you would plant a clump of trees, place a thicket of shrubs presenting a hemisphere the crown of which shall distinctly show itself under the branches of the trees. This may be effected by a due selection & arrangement of the shrubs, & will I think offer a group not much inferior to that of trees. The thickets may be varied too by making some of them of evergreens altogether, our red cedar made to grow in a bush, evergreen privet, pyrocanthus, Kalmia, Scotch broom. Holly would be elegant but it does not grow in my part of the country.
- "Of prospect I have a rich profusion and offering itself at every point of the compass. Mountains distant & near, smooth & shaggy, single & in ridges, a little river hiding itself among the hills so as to shew in lagoons only, cultivated grounds under the eye and two small villages. To prevent a satiety of this is the principal difficulty. It may be successively offered, & in different portions through vistas, or which will be better, between thickets so disposed as to serve as vistas, with the advantage of shifting the scenes as you advance on your way.
- "You will be sensible by this time of the truth of my information that my views are turned so steadfastly homeward that the subject runs away with me whenever I get on it. I sat down to thank you for kindnesses received, & to bespeak permission to ask further contributions from your collection & I have written you a treatise on gardening generally, in which art lessons would come with more justice from you to me."
