left, or behind it. The advantage of these rules being acknow- 

 ledged, the planter has only to make the most of his space, 

 zigzagging the trees from one imaginary line to the other, but 

 never going beyond either. As the positions of the trees and 

 shrubs are found, a pin, or stake, having the number of the 

 plant marked on it, should be driven in, there to remain till 

 the plant is got, and a proper name and number affixed to 

 it, either in Murray's manner (described Vol. III. p. 29.), or 

 in that of Allardyce (p. 33.). The temporary numbers may 

 be either notciied on the stakes, or marked with a pencil on 

 white lead rubbed on a part of the stake or pin, previously 

 cut smooth with a knife. In the centre of every group in- 

 tended for herbaceous plants, a numbered stake should also 

 be put down ; for which is allerwards to be substituted a tally, 

 containing simply the name of the order or tribe, and its 

 number; and the name of the genus for which the group is 

 intended, with its number. Each species, as it is added, will 

 only require the specific name, with or without the initial 

 letter of the genus. It is almost unnecessary to mention, that, 

 where groups of water plants occur in the herbaceous ar- 

 rangement, small basins {[fg- 73. e e e,) must be made for them, 

 proportionate to the spaces which they will occupy, as indicated 

 by figures in the Hortus Britannicus, and by circles in plate 

 vii. of Illustrations of Landscape-Gardening. All the groups 

 and basins for herbaceous plants being notched out, and 

 stakes put in at the proper places for inserting all the trees 

 and shrubs, the surface not occupied by the groups may 

 next be sown with a proper mixture of grass seeds, (p. 176.) 



As the plants and trees are introduced in their places, it 

 will become necessary to introduce with them their appropriate 

 soils ; but this will not interfere with any of the foregoing 

 operations : neither will the circumstance, that with some 

 species of shrubs it may be necessary to prevent the grass 

 from growing within a few inches of their stems ', and with 

 others, to place a bed of small stones round the stems, to 

 prevent them from damping off with moisture. 



Fig. 75. shows the plan, section, and elevation of the pro- 

 posed circular range of hot-houses, the construction of which 

 is so simple, that very little description is requisite. The 

 ground plan (a b c) is exhibited in a dissected state ; one 

 part (a) showing the foundations; another part (b) represent-^ 

 ing the steam or hot-water pipes laid down ; and the remain- 

 ing part (c) exhibiting the beds as filled with earth, and the 

 walks as completed with pavement or cast-iron grating. The 

 details of this plan are as follow : —
