In the year 1879 the Board accordingly made representations to the Government, and suggested that the owners of unhealthy houses should not be compensated in proportion to the profit they derived from such houses, but according to their value as places pronounced unfit for habitation. The Board also pointed out--"the great loss entailed upon the ratepayers by the obligation which the Board was under to provide for the accommodation in suitable dwellings in the same area of at least as many persons as were displaced. This obligation rendered it necessary for the Board to sell, at a very low price, ground, which, with the dilapidated buildings upon it, had cost the Board seven or eight times as much, and which, if the Board had been free to dispose of it for commercial purposes, and to provide for the dispossessed people elsewhere, would have realised a much higher price."[139] On the six areas which had been sold to the Peabody Trustees it was estimated that the Board--or in other words, the ratepayers of London--would lose the large sum of £562,000. The Board suggested that it should have power to dispose of the cleared ground for commercial purposes, and to provide for the re-housing of the displaced families in other parts of London. This latter suggestion was not adopted, but Parliament passed an Act in 1879 which to some extent lessened, though it by no means removed the defects of which the Board complained, for the Board declared that "after careful consideration, it thought it well not to prepare any more improvement schemes until some further experience has been gained of the working of the Amendment Act of 1879." And in 1879, also, an Act[140] was passed which nominally "amended," but in reality destroyed the real good of Torrens' Act of 1868, and gave the owner power to require the local authority to purchase the premises which had been condemned as unfit for human habitation, and which the local authorities were to rebuild and hold--thus practically relieving the worst class of slum house "owners" of any consequences for their malpractices, relieving them, too, in the most open way at the expense of the ratepaying public, as it empowered the Vestry "to levy a rate of twopence in the pound to bear this expense as well as that of building sanitary dwellings on the site." By one means or another it invariably worked out that the slum owner obtained large sums for his vile property, and that the public had to pay heavily for his iniquities. The work which was within the power of the Vestries and District Boards to do, in connection with the sanitary condition of houses, was far more wide-reaching in extent, and more immediately effective than any the Central Authority could do under its powers. Practically the Vestries had under their supervision the sanitary condition of all the houses of London. Moreover they could act upon their own initiative, whereas the Central Authority could only act when representations were made to it.
