History, Use, Propagation, Culture, 
in a shady place, and if a frame be ready with bottom heat, plunge the pots to the brim. 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 cut- 
tings 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, 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. Hart. 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 ^s 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, rela- 
tively 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
