Much of the picturesque on the Rhine is destroyed by the vineyards, which are, in reality, the most unpoetical things in landscape scenery, being ranged up the sides of the mountains in little battalions like infantry. It is remarkable in how shallow and how very poor a soil the vine will grow. At Saint Michael's, they dig square holes in the volcanic rocks, and the vines find sustenance. At the Cape of Good Hope the Constantia vineyards are planted upon little more than sand. I dug down some depth; and could find nothing else. The finest grapes grown in Burgundy are upon a stratum of soil little more than a foot deep, over schistus slate quarries, and the soil itself composed chiefly of the _debris_ of this soft rock. We know that the vegetable creation has a sort of instinct as well as the animal and it appears to me that there are different degrees of instinct in that portion of nature as well as in the other. A vine, for instance, I take to be a very clever plant, and both apple and pear-trees to be great fools. The vine will always seek its own nourishment, hunting with its roots through the soil for the aliment it requires; and if it cannot find it where it is planted, it will seek, in every direction and to a great distance, to obtain it. It is asserted that the famous vine at Hampton Court has passed its roots under the bed of the river, and obtains aliment from the soil on the other side; but an apple or pear-tree will take no such trouble--it will not even avoid what is noxious. Plant one of these trees in the mould three or four feet above the marl or clay; so long as the roots remain in the mould, the tree will flourish, but so soon as the tap root pierces down to the marl or clay below the mould, the tree will canker and die. To prevent this, it is the custom to dig first down to the marl and put a layer of tiles upon it, which turn the roots of the trees from a perpendicular to a horizontal direction, and then they do well; but leave the tree without assistance, and the fool will commit suicide, blindly rushing to its own destruction; while the vine will not only avoid it, but use every exertion to procure what is necessary for its continuing in health and vigour. The vine is therefore certainly the more intellectual plant of the two. CHAPTER THIRTY FOUR. Strasbourg.
