Two hundred and fifty-eight requests for photographs were re- 

 ceived from educational institutions and individuals outside the 

 department, for which $1,007.58 was received and turned over to the 

 Division of Accounts and Disbursements to be covered into the 

 Treasury. 



The increase in photographic work, especially in requests from 

 outside institutions, has taxed the small clerical force of the illustra- 

 tions section to the utmost. Negatives from which prints are 

 wanted are scattered throughout the bureaus and oflfices of the 

 department without a uniform system of filing, which makes it 

 extremely difficult to obtain them for making prints. A print from 

 every photographic negative in the department that can be released 

 for publication should be filed in the illustrations section. It is. im- 

 possible to supply prints promptly without such a system. Supply- 

 ing these prints to the public upon request is a valuable means of 

 diffusing the department's information, and as this section is the 

 one charged with the work, it must be able to locate a negative 

 quickly, and to do so it should have a print of every photograph 

 which may properly be given out. 



Ellectrotype cuts kept on file were furnished for reprints of de- 

 partment's publications, and 2,614 new cuts were received and filed. 

 Kequests for 574 electrotypes were received from individuals and 

 private concerns which were supplied through commercial houses 

 under the usual conditions. Additional space is required for the 

 .storage of cuts. 



The work with illustrations was under the direction of A. B. 

 Boettcher, assistant in charge, until May, 1920, when he resigned. 

 He was succeeded by J. H. Stevenson. 



DISTRIBUTION OF PUBLICATIONS. 



The total number of publications of all kinds distributed during 

 the year was 45,237,747. This distribution was divided broadly into 

 three classes. Farmers' Bulletins forming one class. Lists of Farmers' 

 Bulletins a second class, and all other publications being classed as 

 miscellaneous. The main distri])ution of miscellaneous publications 

 was in accordance with schemes of distribution prepared in advance 

 of their issuance. The distriliution of miscellaneous publications 

 totaled 25,274,618 copies. This was a reduction of 37 per cent in 

 the distribution of miscellaneous publications One reason for the 

 reduction is found in the discontinuance of the great number of pam-
