Nevertheless, the extent of land requisite for cemetery, on a decennial period of renewal, for a population of 20,000 in a rural district would be only 44
10 acres, whilst for 20,000 of such a town population as that of Whitechapel, it would be 74
10 acres.
§ 146. In 1838 the deaths in the metropolis were nearly 52,000; and for round numbers the average maybe taken as 50,000 annually. Such an amount of mortality would require on the scale proposed by Dr. Riecke, for the several classes of graves, about 48 acres, or a space of nearly the size of St. James’s Park within the rails, annually. On the same scale, supposing the interments generally renewable in decennial periods, the space required for national cemeteries in the metropolis would be 444 acres, or a space coextensive with Hyde Park, which has 350 acres, and the Green Park and St. James’s Park put together; or rather more than one-fourth more than the Regent’s Park, which has 350 acres; or one-fourth less space than the Hyde Park and Kensington Gardens taken together. But besides the spaces for the cemeteries, spaces would be requisite as belts of land surrounding them, and to be kept clear of houses.
§ 147. The proper distance of places of interment from houses, is calculable according to the number of interments. On this subject there have been some, though not complete observations. There is a church-yard at Stuttgart, in which 500 bodies are interred yearly, at depths varying with the age, according to the scale of regulations stated, with no more than one corpse in each grave, yet a north-west wind renders the emanations from the ground perceptible in houses distant from 250 to 300 paces. The stench of the carrion pits at Montfaucon is almost insupportable to a person not used to it, at a distance of 6500 feet, and with certain winds at double that distance, and under some circumstances even to the distance of five miles. Besides the surface emanations, the pollution of the subsoil drainage and springs have to be regarded. Captain Vetch states, that on some plains in Mexico, where animals have been slaughtered and buried in pits in permeable ground, the effects on vegetation were to be seen along the edges of a brook for a distance of three-quarters of a mile. In some parts they actually slaughtered and buried animals for the purpose of influencing the surrounding vegetation. By the best regulations in Germany, as already stated, wells are forbidden to be sunk near grave-yards, except at certain distances, such as 300 feet. Ante, §§ 13, 14.
§ 148. On such data as have been obtained, the distance of a cemetery ought to vary according to its size, or the number of the population for whom burial is required. The cemetery for a small population of from 500 to 1000 inhabitants, should, Dr. Reicke considers, be not less than 150 paces; for 1000 to 5000 inhabitants, not less than 300 paces; for above 5000, not less than 500 paces. In Prussia, the distance from houses at which cemeteries may be built, is fixed at not less than 500 paces; at Stralsund, in Prussia, at 1000 paces.
§ 149. It is recommended that in general public cemeteries should be placed at the east or the north, or the north-east of a town: the south and south-west winds, being usually moist, hold the putrefactive gases in solution more readily than the north, or north-east winds, which are dry. The higher the elevation of a cemetery, the nearer may it be permitted to a city, as putrefactive gases are lighter than the atmosphere and ascend. For the same reason, cemeteries lower than the houses should be at a greater distance. A site, with a slope to the south, is deemed the best, as it will be drier and warmer, and facilitate decomposition.
§ 150. Competent witnesses declare, that by a careful preparation of the ground, and without any appliances that would be otherwise than acceptable to the most fastidious minds, the escape of miasma may be so regulated as to avoid all injury to the health, and springs may be protected from pollution by drainage; and that by these means the necessity of far distant sites, and the inconvenience and expense of conveyance of the remains, and obstructions to the access of friends to the place of burial, may be avoided.
§ 151. Amongst these means, one for preventing the escape of emanations at the surface by absorbing and purifying them, is entirely in accordance with the popular feeling. The great body of English poetry, which it has been remarked is more rich on the subject of sepulture than the poetry of any other nation, abounds with reference to the practice of ornamenting graves with flowers, shrubs, and trees. A rich vegetation exercises a powerful purifying influence, and where the emanations are moderate, as from single graves, would go far to prevent the escape of any deleterious miasma. It is conceived that the escapes of large quantities of deleterious gasses by the fissuring of the ground would often be in a very great degree prevented by turfing over the surface, or by soiling, that is, by laying vegetable mould of five or six inches in thickness and sowing it carefully with grasses whose roots spread and mesh together. At the Abney Park Cemetery, where the most successful attention is paid to the vegetation, this is done; but in some districts of towns it marks the impurity of the common atmosphere that even grass will not thrive; and that flowers and shrubs which live on the river side, or in spaces open to the breeze, become weakly and die rapidly in the enclosed spaces in the crowded districts. Several species of evergreens, and the plants which have gummy or resinous leaves, that are apt to retain soot or dust, die quickly. The influence, therefore, of a full variety of flowers and a rich vegetation, so necessary for the actual purification of the atmosphere, as well as to remove associations of impurity, and refresh the eye and soothe the mind, can only be obtained at a distance from most towns. It occasionally happens that individuals incur expense to decorate graves in the town churchyards 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.”
