Shade them well with a double mat, which may remain till they have struck root; when rooted, take the sand and cuttings out of the pot, and plant them into single pots, in the proper compost. Plunge the pots with the young plants again into a frame, and shade them for four or five weeks, or till they are taken with the pots; when they may be gradually exposed to the light. From various experiments, I found that pieces of two year old wood struck quite well; and in place, therefore, of putting in cuttings six or eight inches long, I have taken off cuttings from ten inches to two feet long, and struck them with equal success. Although I at first began to put in cuttings only in the month of August, I now put them in at any time of the year, except when the plants are making young wood. By giving them a gentle bottom heat, and covering them with a hand-glass, they will generally strike root in seven weeks or two months. The citron is most easily struck, and is the freest grower; I , therefor therefore , frequently strike pieces eighteen inches long, and as soon as they are put into single pots, and taken with the pots, they are grafted with other sorts, which grow freely. I am not particular as to the time either of striking cuttings or of grafting." (Caled. Hort. Mem. iii. 308.) At Genoa and Florence, citrus trees are grown in a strong yellow clay, which is richly manured; and this soil is considered by the first Italian gardeners as best suited to their natures. The French gardeners, in preparing a compost for the orange-tree, endeavour to compensate for quantity by quality; because the pots or boxes in which the plants are placed ought always to be as small as possible, relatively to the size of the tree. The following is the composition recommended: to a fresh loam, which contains a third of clay, a third of sand, and a third of vegetable matter, and which has lain a long time in a heap, add an equal bulk of half-rotten cow-dung. The following year turn it over twice. The succeeding year mix it ORDER II. 10981 Leaves oblong POLYADELPHIA POLYANDRIA. 10982 Leaves smaller oval blunt §1. Sepals united at base and unequal.

Turn it over twice or three times, and the winter before using add a twelfth-part of sheep dung, a twentieth of pigeon dung, and a twentieth of dried ordure. Henderson, already mentioned, takes one part of light-brown mould from a piece of ground that has not been cropped nor manured for many years one part of peat earth, such as is used for growing heaths two cropped nor manured for many years; one part of peat earth, such as is used for growing heaths; two parts of river sand, or pit sand, if it be free from with parts of river sand, or pit sand, if it be free from mineral substances and one part of rotted hot-bed dung, all well together, so as to form a compost-soil of uniform quality. (Caled. Hort. Mem. iii. 502.) Though orange-trees will grow exceedingly well in large pots and boxes, yet to have them produce the finest crop of fruit they should be planted in the ground like peach-trees, and trained like them, or as standard cherof fruit they should be planted in the ground like peach-trees, and trained like them, or as standard cherries in a conservatory. The latter has by far the best effect, especially when the stems of the trees are seven or eight feet high, and the head forins a handsome cone; but the largest fruit is produced when the trees are planted against the back-wall trellis of a narrow house, and treated like peach-trees. Henderson grows his largest fruit in this manner, and we have seen them fully as large as any we ever saw at Genoa or Naples. 1616. Xanthochymus. From ξavθoς, yellow, and χῦμa , any thing which exudes: in allusion to the color of the juice which flows from the ripe fruit when wounded, and which, being inspissated, yields a material for the which flows from the ripe fruit when wounded, and which, being inspissated, yields a material for watercolor painting which is as good as Gamboge. Handsome plants, of the usual culture in light loam, and propagated by cuttings in sand under a hand-glass. 1617. Hypericum. A name of unknown meaning. The species are chiefly under-shrubs, generally with dotted leaves, and almost, without exception, yellow flowers. The hardy species are useful for the fronts of leaves, and almost, without exception, yellow flowers. The hardy species are useful for the fronts of Uu POLYADELPHIA POLYANDRIA.
