ART. III. On inoculating the Rose on the Orange, and similar Practices; and on Mr. Long's Paper on the Quercus and Fagus of the Ancients. In a Letter to Major Webb from his Brother, P. B. WEBB.
You tell me you will not believe Mrs. Piozzi's account (Travels in Italy, vol. ii. p. 224., cited in the Gentleman's Magazine, April, 1839, in the article, "Notes on Pinkerton's Literary Correspondence") of the inoculation of a rose on an orange, a fig tree on a lemon, &c., unless I will back her authority. You will be surprised to hear that I am bold enough to undertake this. When at Nice, in 1832-3, my old friend, Professor Risso, took me to see a monstrous "inoculation," similar to those mentioned by that learned lady, and which, I confess, without seeing and feeling like the incredulous St. Thomas, I was loth to believe. However, I did see a cypress, a Catalonian jasmine, an olive, and, I believe, something else, growing sociably together, engrafted on a lemon stock. How this unnatural union was accomplished I could only have learnt by purchasing the tree at an exorbitant price, and dissecting its trunk. I confess, I shrunk before a demand of 2000 francs. The author of the marvel, a common gardener, said that 99 out of a 100 of his pseudo-grafts failed. With some hesitation, as he lives by his secret, he showed me several in their early stage; and, though he stoutly denied it, I am inclined to think that the plants to be grafted are sown in the lemon or orange trunk, and that either they cast their roots into it, or reach the ground through it.
