Since 1883, as complete a list as I could make of the London burial-grounds has appeared in the Reports of the Metropolitan Public Gardens Association, and I have, from time to time, been asked for information about the more obscure ones. In the summer of 1894 the London County Council instructed its Parks Committee to make a return of all the burial-grounds existing in the County of London, with their size, ownership, and condition. Having been applied to for information and assistance, I offered to undertake the work. It involved some additional research at the British Museum, and a fresh perambulation. The offer being accepted I commenced the task in February, 1895, and sent in the return in June, accompanied by 60 sheets of the ordnance survey (25 inch to the mile), upon which the grounds were marked in colours, viz., those still in use blue, those disused green, those converted into public recreation grounds green with a red border. I gave the number existing in the County and City of London as 362, of which 41 were still in use, and 90 were public gardens and playgrounds. This did not include churches and chapels with vaults under them, but without graveyards. It must also be remembered that the area was strictly limited (as it is in this work) to that of the metropolitan boroughs, or the administrative County of London with the City. The cemeteries in the county do not represent all the parochial ones. There are, for instance, those of St. George’s, Hanover Square, and Kensington at Hanwell, the Paddington Cemetery in Kilburn, the Jewish at Willesden, and very many more just outside the boundary, not to speak of a large number in what is called “London over the Border,” which to all intents and purposes is still London, although separated by the River Lea, and governed by the West Ham Corporation. The kindly notice taken of the return, which was published by the Council in October, 1895, has encouraged me to prepare the present volume, in which there is scope for a general view of the subject, for further historical details, and for particulars of those grounds which no longer exist. The more public interest is brought to bear upon the burial-grounds, the more likely is it that they will be preserved from encroachments. The London County Council has special powers to put in force the provisions of the Disused Burial-grounds Act, and it has the record of their actual sites on the plans prepared by me. It is for the public to see that these provisions are carried out, not only for historical, sentimental, and sanitary reasons, but also because each burial-ground that is curtailed or annihilated means the loss of another space which may one day be available for public recreation; and considering that land, even in the poorest part of Whitechapel, fetches about £30,000 per acre, it is easily understood of what inestimable value is a plot of ground which cannot be built upon.
