Many Blind Workers DURING an investigation by Surpass Output of the 1-"the National Institute for Sighted the Blind it was discovered that in certain operations in industry a blind worker often proves more efficient than one with sight. The evidence was collected from 110 concerns employing people who have lost their sight and from 500 of the latter. In machine operations, taking the average output of those who could see at 100, that of the blind was 101.8. The figures for " inspection " (93) and " miscellaneous " (92.9) tasks were not quite so impressive, for although most of the blind workers topped 100, the average in each category was seriously affected by a small minority which proved 'to be fitted only for " assistance " employment. Another interesting discovery was that the totally blind gave a greater output than those only partially afflicted. This seems to be due to the finer concentration of the former, as their interest is likely to be less distracted.
Road Transport and WE were interested to learn Safety of Manchester's VY that the treasures of the Pictures Manchester Art Gallery, some of which have already arrived from Aberystwyth, are being brought back by road transport so as to ensure a rapid and safe journey and permit ,a special staff not only to pack and unload them, but to keep them in view from door to door. Actually, apart from the main Art Gallery, Manchester has four others situated outside the city centre. 1N a recent letter to "The Financial Times," dealing with competition in the export markets, Mr Sydney S. Guy, chairman and managing director of Guy Motors, Ltd., said that it does not seem to be generally known, except to buyers of commercial vehicles, that there is no_ purchase tax on these. Secondly, whilst the competition from American makers of cars may be severe, when considering heavy goods vehicles and buses, for which the demand is comparatively small, this does not justify the high degree of mass production in which our American friends excel. British makers of commercial vehicles are in a much more favourable position, as they appear to have been always more efficient in the production of the smaller quantities. Even in pre-war days, the American largecapacity 'goods vehicles and buses were invariably more expensive than the equivalent British, and with the high wages in the States the disparity is now even greater For these reasons, he viewed the

prospects of the British makers, both from a long and short-term policy, with reasonable optimism Mr. Guy has cause to be optimistic, for his company has already shipped a considerable number of bus chassis abroad, others are ready to go, whilst fleets of vehicles are on order for South Africa, Belgium, Holland, etc.
Preventing Excessive DURING a visit to the shops Stressing of Short of Dennis Bros., Ltd., we Bolts "collected" a useful little tip
which may not be known to all engineers. When a bolt is used in the ordinary way for holding together two comparatively thin articles, its short length is apt to cause excessive stressing of the shank, there not being sufficient Material to provide elasticity. This can be overcome by fitting a collar of suitable depth under the nut, thus increasing the effective length which takes the stress.
