FIMST GET THE FACTS^ 

 There is connected with the Department 

 of Commerce a remarkable institution 

 called the Bureau of Standards. Its work 

 is more or less familiar to you because one 

 or more groups of students from this school 

 have visited it at various times. I have on 

 some occa.sions spoken of this bureau as the 

 "house of accuracy," for in it in a special 

 sense the truth is sought. We call the seek- 

 ing of this kind of truth research. It may 

 be chemical research or physical research 

 or the act of research applied to any of the 

 sciences that underlie our industries and 

 public utilities. Truth is sought in this 

 work because it is believed that the facts 

 concerning nature are of infinite value to 

 mankind. It is recognized that the effec- 

 tiveness of our civilization rests upon facts 

 first ascertained and then used. It is there 

 thought faulty to proceed on the basis of 

 incomplete truth or of undigested facts, and 

 neither time, labor, nor expense is spared 

 to find the facts and make them known to 

 those who can use them. 



One of the standards of the Bureau of 

 Standards itself must be that of speaking 

 the truth so far as it shall have become 

 known, and men know they may depend 

 upon what it says as expressing the truth 

 within those limits in which it has been 

 ascertained. To tell half of a truth if the 

 other half were known would be thought 

 a destructive violation of the very raison 

 d'etre of the service. To know the truth 

 and not to tell it would be equally violative. 

 In what has been thus far said I have 

 1 Address of The Honorable William C. Eedfield, 

 Secretary of Commerce, before the Case School of 

 Applied Science, Cleveland, Ohio, May 27, 1915.
