xIvili RESOLUTIONS AND RECOMMENDATIONS 
From Section F (Economics), supported by Section # (Psychology). 
The Committee recommends that the Association might indicate the 
importance which it attaches to the development of the social sciences by 
appointing a third General Secretary, who would be specially associated 
with this group of studies. This emphasis would convey to the public 
that the Association has always regarded this form of scientific inquiry as 
it regards the mathematical, physical, and biological sciences. 
From Section G (Engineering). 
Section G recommends that the desirability of adding, for those who 
desire to use it, a definition and specification of the lower yield-point to the 
specification of other properties of mild and moderately high tensile steel 
be brought to the notice of the British Standards Institution. 
The Section submits the following specification for consideration by 
that Institution : 
‘ After yield has commenced in a tensile test on a standard piece (com- 
prising a portion that is tolerably uniform in section) and before it has 
spread along the whole of the portion of uniform section, the load shall be 
readjusted to a new, steady value (being reduced if necessary) so that yield 
spreads along the uniform portion while the machine continues to elongate 
the piece slowly. The stress value deduced by dividing the readjusted load 
by the initial cross-sectional area of the uniform portion of the test-piece 
shall be known as the lower yield-point.’ 
From Section H (Anthropology). 
That the Council of the Association be asked to approach H.M. First 
Commissioner of Works with a view to the immediate scheduling of the 
Pin Hole Cave at Creswell Crags, Derbyshire, as an Ancient Monument, 
and to a proper protection of the site. At the same time it was recommended 
that the following cave sites in the neighbourhood be also scheduled, namely, 
Mother Grundy’s Parlour and Langwith Cave. 
From the Conference of Delegates of Corresponding Societies, supported 
by Section D (Zoology). 
(1) That the attention of the respective Councils for the Preservation of 
Rural England, Scotland and Wales be called to the serious effects upon the 
insectivorous bird population through the cutting of hedgerows during the 
breeding season, and the consequent destruction or desertion of the birds’ 
nests ; and recommends that the said Councils urge upon local adminis- 
trative authorities the desirability of suspending such operations during 
the nesting period. 
(2) That this Conference of Delegates of Societies in correspondence 
with the British Association for the Advancement of Science assembled at 
Norwich welcomes the facilities afforded by the Town and Country Planning 
Act, 1932, for the preservation of individual sites and objects of scientific 
interest, but views with grave apprehension the indiscriminate building 
development over wide areas of exceptional natural beauty and scientific 
importance ; and requests the Council of the Association to represent to 
H.M. Government the urgent necessity for taking immediate steps to 
schedule such areas, as recommended by the National Parks Committee 
(Report, Section 28 b), 1931, to be developed as national parks.
