OFFICE OF THE SOLICITOR. 



495 



After preliminary correspondence and conferences, recommenda- 

 tion was made to the Attorney General for presecution of a firm for 

 its failure to fill out and return the food schedules as requested. 

 When proceedings were about to be instituted the firm filled out 

 and returned the schedules and the department recommended that 

 the case be dismissed. 



MISCELLANEOUS WORK FOR THE BUREAU OF MARKETS. 



Various letters, memoranda, news items, manuscripts, Service and 

 Regulatory Announcements, and proofs of bulletins relating to the 

 work of the Bureau of Markets were prepared, approved, or revised. 

 Questions relating to the conduct of cooi:)erative work between State 

 agencies and the department relative to marketing and other activi- 

 ies were considered in conferences and correspondence. Alleged ex- 

 cessive prices charged for thrashing in certain districts in the North- 

 western States were considered. Protests of the Spanish, Portu- 

 guese, and French Governments against the then proposed wartime 

 prohibition legislation were considered. Aid was given in the con- 

 sideration of a controvei^s}- in New York City relative to the proper 

 disposal of city garbage and of questions arising out of alleged un- 

 fair practices of several broom-corn dealer's. Assistance was given 

 the bureau in the preparation of a report on the investigation of 

 grain-marketing practices in Chicago and Minneapolis.
