416 Description of a Design for the 



rating the bonlcrs {t /) from the orcliard, the kitchen-garden, the Ame- 

 rican, and the Horist's {garden. 



/ t, Border of flowers arranged for a perpetual succession during tlie 

 greater part of tlie year. 



«, Dotted lines, representing the proposed holly hedge within the existing 

 hawthorn hedge. 



V, Double lines, dotted, representing the situation of the main pipes for 

 conducting the water from the cistern x to the ditterent fountains, and 

 also of another pipe for conducting the water from the forcing-pump 

 at w tax. 



w IV, Pipe-drains from the springs u u to v. 



X y. Space in which the arboretum is omitted, in order not to shade the 

 peach wall u ; but in which the herbaceous arrangement is continued. 



z. Pits or hot-beds in the experimental garden. 



Fiij,. 72. is a vertical profile of the garden, on the supposition 

 that all the hot-houses are executed, and that the trees and 

 shrubs have had 10 or 12 years' growth. 



Fig. 73. is a working-plan of a small portion of the botanical 

 arrangement. In this plan, the situations for the herbaceous 

 plants are shown chiefly as circles ; each circle having marked 

 beside it the number of the genus for which it is intended, 

 agreeably to the enumeration of the Hurtus Britamiicus. The 

 size of the circles is also proportioned to the number of hardy 

 herbaceous plants given in that work ; and, according to the 

 calculation of the space dug, will occupy as indicated under 

 each natural order in Part II. (See Hart. Brit., Explanatory 

 Introduction to the Natural Orders, p. 491. ; and Illustrations 

 of La7id scape-Gar dc7ii7igi &c., Part II. plates vi. and vii.) 

 The small crosses (X), with the numbers attached to them, 

 show the positions of the trees and shrubs; the numbers in- 

 dicating the species or variety in the Hortus Britanniciis. The 

 dotted lines, a b, are in":aginary lines, to be drawn on the 

 ground when planting, in order to preserve a clear space of 

 the width of a walk, c c. The dotted lines, d d, are also 

 imaginary ; and must be drawn on the ground, when planting, 

 to prevent any of the trees or shrubs from being i)lanted 

 within a certain distance (5 ft.) of the groups of herbnceous 

 plants. It will be observed from the enumeration, that both 

 herbaceous plants and trees proceed in the order indicated by 

 the arrows); and that the herbaceous orders are distinct from 

 those of trees: this being unavoidable, except in gardens many 

 tiujcs the si/c of the botanic ground before us. 



In executing this botanic ground, the first process is, 

 to drain, level, trench, and smooth the surface. Then to 

 put down the groups of herbaceous plants, none of them 

 nearer to the walk than, say 3 ft., or nearer to each other 

 than, say 2 ft. ; always preserving 3 ft. between the last genus 

 of one order or tribe, and the first genus of that which
