covered with a bell-glass, and kept moist and 

 shaded, will strike root in about two months. 

 They should be put in in August or September. 



Layering is a slow process. A 5-inch pot 

 filled with soil may be raised to where a two- 

 years-old shoot can be fixed in it. The shoot 

 should be notched just 

 where it is to be pegged 

 down into the soil, 1 inch 

 or so deep, and if properly 

 attended to a well-rooted 

 layer ought to be ready for 

 detaching from the parent 

 plant in about a year. 



For the plants in these 

 early stages of growth the 

 compost may consist of 

 good fibrous loam two 

 parts, leaf soil one part, 

 adding some sharp sand, 

 charcoal, and crushed 

 bones. 



Insects. — All the Orange 

 family are subject to in- 

 sects, the most trouble- 

 some of which is scale. If 

 affected with the white 

 scale, there is little chance 

 of eradicating the pest 

 without cutting the trees 

 well back into the hard 

 wood, as the leaves cannot 

 bear a dressing strong 

 enough to kill the insects. 

 After this heading down, 

 a thorough washing with 

 insecticide, used accord- 

 ing to instructions received 

 with them, repeated two 

 or three times in the course 

 of a fortnight, before the 

 young buds have begun to push will, if carefully 

 carried out, completely free the trees. For brown 

 scale a good syringing in the winter, before 

 the flowers begin to move, with a weak solution 

 of paraffin will leave few of the insects alive. 



List of varieties : — 



Oranges. 



Blood (Malta). — Pulp stained with deep-crimson; fruit 

 large; skin thin; delicious; the foliage and growth differ 

 greatly from the St. Michael's. A story believed by 

 credulous travellers is that the blood-stain was produced 

 by the union of the Pomegranate with the Orange. 



Embiguo, or Navel Orange. — A singular variety, with 

 a nipple-like excrescence at the apex ; fruit large and 

 good; pulp pale in colour. 



Horned Orange (Citrus corniculata). — A curious variety, 

 not edible. 



Jaffa. — The largest Orange in cultivation. 



Oval (Malta). — Like the Blood Orange in size and form 

 of fruit, but without blood-stains in the pulp. Produces 

 flowers abundantly. 



Seville. — The variety used for marmalade. Produces 

 the finest flowers freely. 



Silver, or Plata. — A delicious Orange. This and other 



0h O 



Fig. 1097. -Shaddock (Citrus decumana). (i) 



varieties of the St. Michael's have been selected as being 

 the most excellent. 



St. Michael's (fig. 1093). — The ordinary Orange of com- 

 merce, thin-skinned, large, and well-flavoured, Botelha, 

 Dulcissima, Egg, and Exquisite are varieties of St. Michael's 

 differing in foliage and form of fruit. 



Sustain. — Also a variety of St. Michael's, but re- 

 markable for the delicacy and high flavour of the 

 pulp. 



Tangierin. — A delicious little Orange. The rind parts 

 freely from the pulp, which has a delightful aroma. 



Tangierin (St. Michael's). — The same size as the pre- 

 ceding, but superior in flavour. These two sorts are 

 comparatively hardy, and may be grown to perfection in 

 an orchard -house. 



Variegated Orange. — An ornamental sort, the leaves and 

 fruit being variegated; the fruit is exceedingly good for 

 the table.
