4S4< Plan for the Formation 



let every plant indigenous to the hyperborean shores be 

 planted : the various lichens, mosses, &c. : organic remains, 

 whether fossil or not, may be added as part of, or fixed on, the 

 exterior ; such as whale bones, testacea, horns of the elk, &c. 

 A thickly planted row of the Pmus >4^bies, or of the Scottish 

 pine, may be the line of division between this and the next 

 subdivision, answering to the northern side of the north 

 temperate zone ; and here, on each side of the walk, let 

 there be planted in amphitheatrical order, the trees, shrubs, 

 and herbs natives of the corresponding parts of the world. 

 This order of planting and arrangement must be continued 

 throughout the whole length of the garden, with this ob- 

 servance, that, in order to produce variety, the turf on each 

 side of the walk must be carried, in irregular sinuations, into 

 the planted ground on either side, and on which, at proper 

 intervals, may be planted the most conspicuous, useful, or 

 beautiful specimens of indigenous plants of the correspond- 

 ing latitudes. Proceeding eastward, and approaching the 

 eastern side of this subdivision, its native plants will re- 

 quire a glass case to preserve them during the rigours of 

 our winter. Here let us enter a Gothic conservatory, of 

 such amplitude as will agree with the general extent of the 

 garden, and suffice to contain the best of the plants which 

 usually require a place in our green-houses. This build- 

 ing must, in its span, include the principal walk : its struc- 

 ture is, perhaps, of all others, the most suitable, from the 

 facility it affords of arranging the glazed lights, its but- 

 tresses with their pinnacles as uprights, the flying buttresses 

 as rafters, to support (assisted by interior columns) the mid- 

 dle or highest part of the roofs ; two or three of the but- 

 tresses behind doing the office of chimneys. This erection, 

 whether when the lights are on in winter, or when off in 

 summer, will always present a pleasing architectural object. 



Leaving this conservatory, and at the distance of a few 

 yards from it, we may pass through a Grecian arch, flanked 

 by a barrier of rockwork, formed of geological specimens 

 from the latitudes of from 20° to 23° north. This arch may 

 be enriched and made interesting by a display of sculpture, 

 emblematical figures, costumes, &c., of the inhabitants of 

 Greece, Persia, and northern India : the ends of the barrier 

 may be concealed among the shrubs and trees at each end. 



We next enter the central subdivision, intended for plants 

 of the torrid zone ; and here, from a luxuriant thicket of 

 evergreen trees and shrubs, let the mosque with its ample 

 •dome swell into the sky, surrounded by its corridor, orna- 

 imented by its minarets, and backed by a pyramid to do the
