20. Crown tenant's option---Where a fence was erected under the
 provisions of the Fencing Act 1908 dividing any land held by any person
 as Crown tenant from any adjoining land, and, before the commencement of
 this Act, the tenant exercised the option conferred on him by section 20
 of the Fencing Act 1908 to pay to the person who erected the fence, or
 to his successor in title, interest on the proportionate share of the
 cost of erecting the fence for which he may have been liable as an
 occupier instead of paying that proportionate share, that Crown tenant
 shall continue to be liable to pay to that other person (or his
 successor in title) interest on that share at that rate during his term
 of occupation of the Crown land.
