Although the area is comparatively small the rateable value is enormous.
But for certain purposes these boroughs are part of the county and rateable to county rate, e.g.
If, however, the total debt of the council will, with the amount proposed to be borrowed, exceed onetenth of the annual rateable value of the property in the county, the money cannot be borrowed unless under a provisional order made by the Local Government Board and confirmed by parliament.
These expenses are payable out of a common fund which is raised out of the poor rate of the several parishes in the district, according to the rateable value of each.
