THE DIVISION OF STATES RELATIONS OF 

 THE NATIONAL RESEARCH COUNCIL 



A STATEMENT Concerning the work of the 

 division has been issued by the council, in 



which the chairman. Professor John 0. 

 Merriam, of the University of California, 

 writes: 



The Division of States Relations is organized 

 with special reference to the consideration of re- 

 search interests related to organization of the 

 states as political and economic units. In our com- 

 monwealth the state presents an important form of 

 organization for the development of certain aspects 

 of science. The function of science in such a unit 

 is to direct the conservative use of the state's nat- 

 ural resources, to increase productivity, to improve 

 sanitation, and in other ways to promote prosperity 

 and the public welfare. The purposes of this di- 

 vision may be stated in simplest form as follows: 



1. To obtain information as to the most effective 

 types of organization for groups of departments 

 concerned with research within state governments. 



2. To become acquainted with the best methods 

 of cooperation among the institutions within the 

 state — educational, commercial and industrial — 

 which are concerned with scientific research. 



3. To study the wider outside relations of re- 

 search in state organizations, including the con- 

 tracts with activities of other states and with na- 

 tional agencies of the country. 



However, much information upon the present 

 situation is needed before steps can be suggested 

 for the closer coordination of state scientific agen- 

 cies. The division is, therefore, undertaMng a 

 study of the present relationships of the various 

 scientific agencies in the govermnent of a number 

 of the states. Several systems for the organiza- 

 tion of state scientific departments are in opera- 

 tion, some, presumably, with better effect than 

 others. Relations have been variously developed 

 ibetween these state departments and the scientific 

 groups in state educational institutions. The re- 

 lation between research work in many state depart- 

 ments and the work of enforcing the regulations 

 based upon scientific investigation has attracted at- 

 tention from the point of view both of science and 

 of political economy. Moreover, determination of 

 the most satisfactory forms for central bodies 

 which may be used to organize scientific effort 

 ■within states, and of the auspices imder which such 

 bodies should act will require much careful study. 

 The nature of the state organization must be 

 adapted to the particular situation found in the 

 state in which it may seem desirable to organize 

 such a body. It is believed that careful review of 

 present conditions and of means for improving 

 them is warranted by the possible gains in the
