With respect to the ordinary arrangement of your ground for public purposes, and the distribution of burials therein, you may estimate that, taking one grave with another, and allowing for the marginal spaces of each, the average size of a grave will be twenty-eight square feet. For illustration’s sake, I will suppose the ground to be laid out in plots--say the third of an acre in extent. Each such plot would contain four hundred single graves, mixed adult and young, with what foot-paths might be requisite for approaching them. The City mortality of twenty years (assuming this period to be the ordinary leasehold of a grave) might be reckoned at sixty-four thousand deaths; for the accommodation of which number there would be wanted one hundred and sixty plots of the above-mentioned size--say fifty-four acres of ground. I would propose that throughout each line of every such space, adult and infant graves should, as far as possible, lie alternately; and that, instead of filling all the graves together at stated periods (say every twenty years) half of them, taken alternately, should be filled at each semi-period--say every ten years. By this arrangement, half the complement of burials would take place in each plot, at a time when the decomposition of the preceding half-complement had finished itself, so far as putrefaction is concerned; and whatever contamination of air might be liable to occur under the best-considered sanitary arrangement, would certainly be reduced to the lowest conceivable amount. Or, as an alternative equal to this arrangement for the purposes of health, you might adopt the plan of filling in immediate succession all the burial-spaces of a plot; provided the surface could then at once be devoted to the growth of appropriate vegetation. Fifty-four acres being then the quantity of ground which would suffice, on sound principles, for the ordinary interment of your entire annual mortality during a period of twenty years; at the expiration of which time (assuming your soil to be appropriate) one may reasonably expect that the ground will admit of a second similar occupation; and so forth in perpetuity: it will be requisite to add a considerable allowance of space for other accessory purposes. Thus, room would be required for the various buildings that belong to the institution of a Cemetery: partly for the dwelling of such officers as you may require to be there resident, partly for the temporary accommodation of persons resorting thither for the burial of their friends, partly for the religious services of different congregations.[95] [95] The distinction of the ground into a consecrated and an unconsecrated portion, as required by the Act of Parliament, will require no addition to its total area; and therefore the proportion which these parts should bear to one another need not now be discussed.
