the problems on which they are working. In short, the exhihits by scientists 

 and institutions give unsurpassed opportunities for conferences between 

 experts on important scientific problems and methods in the atmosphere of 

 the laboratory. 



Publishers of scientific books find at the meetings of the Association large 

 numbers of prospective purchasers of their publications. The members of the 

 Association look over the new books in their fields not only to decide what 

 they will themselves purchase but to make recommendations to libraries and 

 for adoption for classroom use. 



Once scientists worked in garrets with instruments of their own construc- 

 tion. Now the progress of science is essentially dependent on those who make 

 the enormous variety of instruments and equipment that scientists use. No 

 astronomer could construct a 100-inch telescope ; no biologist could make his 

 own compound microscope ; no chemist could produce the delicate scales he 

 uses in his work; no medical man could design an electrocardiograph that 

 would function. Specialists design and manufacture all such things, often at 

 very great cost in time and money. They and the scientists together promote 

 the advancement of science. For these reasons the Association welcomes the 

 manufacturers of scientific equipment, apparatus and supplies of all kinds in 

 their annual science exhibitions.
