Publications. 



The Station is organized so that the work of investigation 

 is distinct from the work of inspection. The results of investi- 

 gation are published in the bulletins of the Station and in sci- 

 entific journals, both foreign and domestic. The bulletins for 

 the year make up the annual report. The results of the work 

 of inspection are printed in publications known as Official In- 

 spections. These are paged independently of the bulletins and 

 are bound in with the annual report as an appendix thereto. 

 Miscellaneous publications consisting of newspaper notices of 

 bulletins, newspaper bulletins and circulars which are not paged 

 consecutively and for the most part are not included in the an- 

 nual report are issued during the year. Weekly mimeograph 

 publicity letters are sent to all papers within the State.
