that land of the nature which would be required for National Parks can 
be purchased in Scotland for £1 or 25s. per acre—say 30s. an acre at most 
or £1,000 per sq. mile. At this price the 2,000 sq. miles which has been 
suggested as a suitable allocation of National Park to Scotland would be 
acquired in twenty-five years. It might include the Glen Affric, Glen 
Cannich, Glen Strathfarrar region, with an extention across the Glencarron 
Road to Loch Coulin and Loch Maree; the region between Invergarry 
and Loch Hourn; the Cairngorms ; some part of the Trossachs, and an 
area in Central Perthshire, perhaps around Glen Lyon. 
In England and Wales, where land is dearer, progress by purchase would 
be less rapid. On the other hand, however, there are in England large 
areas of common lands (estimated at 2,500 sq. miles) and of Crown Lands 
(including the New Forest and the Forest of Dean), much of which would 
probably be selected for Park purposes, and would entail either a very 
low purchase price or none at all. Private generosity also might be relied 
on for substantial aid in extending the area in actual possession and full 
use. With an annual Government expenditure of about £160,000 on land 
purchase to supplement the areas derived from these sources, and with all 
the land that is ultimately desired receiving protection until such time 
as the Nation is ready to purchase it, there can be no doubt that in England 
and Wales, as in Scotland, we should, twenty-five years hence, possess or 
control a system of National Parks of which we need not be ashamed in 
face of our posterity. And the question is not: whether we can—our 
resources. both in money and in land are ample for the purpose; the 
question is only : whether we will. 
Mr. A. FARQUHARSON.—Population maps, their preparation and significance. 
Mr. Farquharson exhibited and described a series of maps he had pre- 
pared of various districts indicating the distribution and density of 
population in urban and industrial areas. He described various methods 
of preparation and dealt at length with the purpose and value of such maps 
for sociological study. 
Prof. Fawcett (Sec. Population Map Committee) speaking in support 
of the subject indicated that he would welcome the assistance of Corre- 
sponding Societies in the preparation of such maps of their respective areas, 
and invited those societies willing to assist to communicate with him— 
Prof. C. B. Fawcett, University College, London, W.C. 1—for information 
and advice. 
The Conference considered and supported the following recommenda- 
tion received from Section E (Geography) :— 
REVISION OF ORDNANCE SURVEY MAPS. 
The delay in revision of Ordnance Survey Maps is of long standing, and 
_ has been repeatedly brought to the notice of the Association, and by the 
Association to the Government, but without appreciable result. 
The cumulative delay results in needless expenditure of large sums by 
local authorities and private enterprises in the construction of unofficial 
maps to replace useless sheets, and has been recently the subject of vigorous 
comments in the Press. The principal grievance is that the geographical 
features of large areas formerly rural, are being transformed for various 
urban purposes. But the Ordnance Survey is under administrative control
