[OcTOBER 12, 1916 
Trade Journalists, and the British Association of 
Trade and Technical Journalists paid a visit to these 
cities on October 8-10. At Leeds University the visi- 
tors were received by the Vice-Chancellor, Dr.._M. E. 
Sadler, who gave an inspiring address descriptive of 
the University’ s work and its close associations: with 
local industries. The departments visited included 
those dealing with organic and tinctorial chemistry, 
leather manufacture, textile work, gas and fuel. The 
members of the party were then the guests of the 
Leeds Luncheon Club, after which the Leeds Army 
Clothing Depét, the works of Messrs. Albrecht and 
Albrecht (khaki garment manufacturers), and the Car- 
digan Boot Factory were inspected, these industries 
being selected in view of their close connection with 
the work of the University. Finally, the visitors were 
the guests of the Lord Mayor for tea. At Sheffield 
the Vice-Chancellor, Dr. H. A. L. Fisher, also ad- 
dressed the visitors, who were conducted over the 
chemical and medical departments, while Prof. Ripper 
gave an account of the many special interesting re- 
searches undertaken on metallurgy and the testing of 
steel, The factories visited included the armament works 
of Messrs. John Brown and Co., where the party was 
invited to lunch by the Master Cutler, and the shell 
factory of Messrs. Thos. Firth and Sons. A. feature 
in the arrangements at both cities was the co-operation 
of journalists representing the local papers, and the 
visits furnish an interesting illustration of the grow- 
ing desire for closer relations between the universities 
and the Press. The visitors were much struck by the 
pride taken by Leeds and Sheffield in their universi- 
ties, and the general recognition among local manu- 
facturers of the value of the work that is being done 
there.
