496 SECTIONAL TRANSACTIONS.—E. 
The pleasurable, or zsthetic, impression of landscape has, however, 
relatively little to do with what we can see when we try, but, on the contrary, 
depends upon what we notice when we make no conscious effort. ‘The 
investigation of this branch of psychological optics is ‘herefore indispensable 
to the creation of an esthetic science of scenery. In the present paper the 
author describes the methods which he has employed to ascertain the modes 
of selective action by which the eye unconsciously provides the ordinary 
man with a vision of the landscape which is, in fact, an artistic composition. 
The review includes examples relating to impressions of tone, colour, 
form, magnitude, multitude and movement in the landscape of different 
climates and latitudes. 
Mr. J. A. Steers.—Scolt Head Island: a study in physical geography 
and ecology (10.45). 
Scolt Head Island, on the Norfolk coast between Hunstanton and Wells, 
affords excellent scope for the study of (1) constructional coast forms, 
(2) comparatively rapid erosional changes, and (3) the relations of plant 
ecology to shore-line studies. 
It is a National Trust area, and is best known as a bird reserve. But 
the geographer has much to interest him both on the island and along the 
adjacent coast. 
The origin of the island is rather uncertain, and is here discussed. One 
of the more interesting problems that yet await solution is the possible 
light that archeology may throw on this problem. ‘Two ancient encamp- 
ments are very close to the area, one being in marshland. Their excavation 
may afford very interesting results. This island is a long sand and shingle 
formation, with numerous recurved ends running back from it. Within the 
main beach and between the laterals is an admirable development of 
saltmarshes, with characteristic flora. 
On the mainland side of the creek which separates the island from the 
land are some other shingle ridges which have apparently been built in a 
direction (i.e west to east) opposite to that of the main island. They are 
directly comparable with the ridges still forming on the distal end of 
Brancaster Golf Links. 
Near by is a submerged forest, the future investigation of which should 
afford some data for the chronological history of the island. 
Col. M. N. Macteop.—The mapping of the Empire (11.30). 
The mapping of the Empire has barely begun, and the lack of maps is a 
serious obstacle to ordered development. Much money has been wasted 
in the past on this account. 
To remedy this situation the first thing is to find the money. Surveya 
are most necessary in those colonies least able to pay for them. Progress 
will be slow unless the money can be borrowed. ‘The Colonial Development 
Fund was established for such purposes. Having found the money, the 
next thing is men. Enough trained surveyors are not available. Air 
survey provides a new and suitable technique, but is hampered by the high 
cost of photography and the lack of geodetic foundation. 
Geodetic surveys of the Empire are particularly backward eae more 
energetic prosecution is especially necessary. Finally there is the question 
of revision. Every scheme for systematic survey should include provision 
for periodical revision.
