§ MR. GREAVESasked the Chairman of the Board of Works, When it is probable that the Ordnance Survey, which is officially stated to have been commenced under General Roy in 1783, will be so far advanced as to furnish the public with a map of the whole of the mainland of Great Britain?
§ MR. AYRTON,in reply, said, the map of Great Britain would not be complete for some time. The one-inch map for England and Wales was already published. The map of Scotland would be complete in four years, and in six years the entire series of maps would be furnished, with the hills all shaded in.
