By this Act certain parts of previous Acts are repealed; power is given to the lessees to pull down all buildings standing upon the premises comprised in any under-lease; the Bishop’s chief rent of forty-three pounds, six shillings and eightpence, is no longer to be charged on the whole of the hereditaments and premises; all lands comprised in the under-leases, to be exonerated and indemnified from the payment of the same; and the signatures of Sir John Morshead, Robert Thistlethwayte, and their wives, to the under-leases are to be no longer necessary. The sale of brick-earth, sand, gravel, &c., having been found totally inadequate for payment of costs of Acts, making drains, streets, &c. {87b} Beilby Lord Bishop of London {87c} and the trustees of the estate agree to execute a mortgage of “a competent part of the said premises,” charging it with any sum not exceeding ten thousand pounds, with lawful interest, for these purposes; or the money may be raised by annuities for lives instead of mortgage. The eighth section of this Act relates to the “conduit upon the said estate belonging to the corporation of London, situate near Bayswater, and the pipes or drain therefrom, and the tanks or wells connected therewith.” And it is stated that as these pipes “run through the same estate diagonally so as to intercept the carrying on of the building improvements upon any eligible plan,” the Bishop and his lessees were empowered to treat with the mayor and commonalty and citizens of the said city of London, for the removal or varying the line of the said pipes, &c., and to make satisfaction for all damages which may be sustained by the city in consequence thereof: the estate to be charged with any sum not exceeding two thousand pounds for effecting this object. Provision is made in the tenth section—“That nothing herein contained shall extend, or be constructed to extend, to authorize the making or forming any new drain or drains, tunnel or tunnels, except for the conveying and receiving the water from the conduit as aforesaid, which shall or may run into the Park, called Hyde Park, or Kensington Gardens, or into any drain, &c., running into or communicating with the same places, or either of them.” But the rights, powers and authorities, vested in the Commissioners of Sewers, were not to be affected by this Act.
