340 TIIE FLORIST. 



not succeed at Paramatta ; it cannot endure any frost, which, though 

 not sufficient there to produce ice but very rarely, or to injure the 

 Orange, would kill the Lime. All the Limes that I have seen are of 

 low growth ; while the Orange and the Lemon rise to a good height, — 

 twenty-five feet or more. The culture of what I call the hardy sorts 

 of the Citrus genus is much the same ; they all require a sheltered 

 situation, a rather dry, strong soil, on a gentle slope : though moisture 

 is not disagreeable to them, yet a wet or swampy ground is not suitable 

 for producing good fruit, or preserving the health of the trees ; it should 

 have a rich mould on the surface, with a deep, tenacious subsoil, into 

 which their fangs, or strong, deep-holding roots can penetrate, so as to 

 support the tree in hot and dry seasons. 



•The sweetest fruit is produced after hot summers. A sandy or 

 porous rocky ground is not fit for them. Indeed the Orange may be 

 said to be very fastidious in its choice of situations, soils, &c, and is 

 very sensible to injury, which it does not soon overcome, nor does it 

 bear much pruning ; it is, I think, the better for having its branches 

 near the ground, so as to shade its roots. 



GEOMETRICAL ARRANGEMENT FOR AN AMERICAN 



GARDEN. 

 References to Plan. 



a. — General turf level of great panel. 



b. — Easy turf sloping descents into panel, angle 22£ degrees. 



c. — General turf slope bounding panel, angle 30 degrees. 



D. — Middle level of turf, with beds cut out thereon. 



e. — Gravel walks round the entire garden, with large circles at the angles. 



f. — Gravel slope of easy gradient — 1 in 5, or angle of 9 degrees ; the broad sloping 

 banks on each side are formed at the same angle. 



o. — Stone steps in mitres of the sloping banks, with side blockings, and termi- 

 nating piers and vases. 



n. — Upper level broad turf promenade. 



I. — Circular recesses in angles, each containing a seat forming three-fourths of a 

 circle. 



K. — Winding gravel approaches. 



l. — Architectural approaches on two sides, by which it is connected with a series 

 of geometrical arrangements. 



m. — Stone fountain in the centre. 



n. — Stone pedestals for large tazza vases or groups of statuary. 



o. — Eight large compound beds formed and planted as follows : — the space 

 between the two outer lines is a slope of turf rising 18 inches above the 

 general level, a., between the second and third lines is flat turf; and the 

 remainder is to be filled up with shrubs. An Irish Yew is to be planted 

 in the centres of the terminating circles in each bed, each Yew being 

 surrounded by a different variety of dwarf Heath, planted sufficiently 

 close to cover the entire space within the circles. The main portions of 

 the clumps are to be filled each with a distinct choice variety of large- 

 flowering Rhododendron; and surrounded, as shown by dotted lines, each 

 with a line of some different dwarf species, as hirsutum, daphnoides, &c. 



p. — Standard Rhododendrons, in pairs, of different choice kinds, carefully 

 selected as to size, habit, colour, &c. 



q- — Large clumps, to be filled with Ghent Azaleas, and margined by a line of 

 Rhododendron ponticum variegatum, cut in well every year just before 

 making its new growth, that it may always be kept dwarf.
