with flowers, and more would do so, even in the churchyards near thoroughfares, but that they perish. § 152. Mr. Loudon recommends for planting in cemeteries, trees chiefly of the fastigiate growing kinds, which neither cover a large space with their branches nor give too much shade when the sun shines, and which admit light and air to neutralize any mephitic effluvia. Of these are, the Oriental Arbor Vitæ, the Evergreen Cypress, the Swedish and Irish Juniper, &c. For the same reason, trees of the narrow conical forms, such as the Red Cedar, and various pines and firs are desirable. In advantageously situated cemeteries, some of the larger trees, such as the Cedar of Lebanon, the Oriental Plane, the Purple Beech, the dark Yew, and the flowering Ash, sycamores, Mountain Ash, hollies, thorns, and some species of oaks, such as the Evergreen Oak, the Italian Oak, with flowering trees and shrubs, would find places in due proportion. § 153. There is one point of view in which the site of cemeteries does not appear to have been considered on the continent, and perhaps in no place could it be of so much importance as in London, namely, the convenience of access for processions, including in the consideration the protection of the inhabitants of particular quarters from an excess of funereal processions, and the mourners from the conflicting impressions consequent on a passage through thoroughfares crowded by a population unavoidably inattentive. It might be found on a survey that the banks of the river present several eligible sites for national cemeteries, and one pre-eminent recommendation of such sites would be the superior and economical means of conveyance they would afford by appropriate funereal barges, for uninterrupted and noiseless passage over what has been denominated “The Great Silent Highway.” _Extent of Burial Grounds existing in the Metropolis._ § 154. The rule, as deduced (§ 142.) from the German practice, would give an average of 110 burials per acre per annum in a town district.
