BRAZILIAN INTERNATIONAL CENTENNIAL EXPOSITION. 



According to a joint resolution of Congress accepting the invita- 

 tion of the Republic of Brazil to take part in an international ex- 

 position to be held in Rio de Janeiro in 1922, the Secretary of Com- 

 merce is " authorized to collect and prepare a suitable exhibit of 

 the fisheries industry of the United States for exhibit at the said 

 exposition and accompany the same with a report respecting such 

 industry, to be printed in the English, Spanish, and Portuguese 

 languages." As the United States commission to the exposition al- 

 lotted but 900 square feet of floor space and less than $5,000 for the 

 assembling of the exhibit in Washington, D. C, the exhibit has of 

 necessity been small. It is educational in character, showing the 

 relationship of the Federal Government to the fisheries, the diversity 

 and character of our fisheries and fishery products, possibilities of 

 American markets as a source of raw materials required in the fish- 

 ing industry, and opportunities for acquiring industrial education 

 afforded those who may wish to specialize in this field. The exhibit 

 includes displays representing the New England offshore fisheries, 

 the salmon industry, the sardine industry of Maine and California, 

 the oyster industry, the fresh-water mussel industry, the fish-can- 

 ning industry, by-products of the fisheiies, and an illustrated story of 

 the bureau's organization and activities. The report deals with the 

 fisheries of the United States, the organization and functions of the 

 bureau, and the opportunities afforded students of fisheries in the 

 United States to acquire industrial education in this field. The 

 bureau is allowed but a single representative at the exposition, which 

 is scheduled to open September 7, 1922. and close March 31, 1923.

 lime, was $8,351,827. The results of the canvass were pulDlished and 

 distributed to the trade as Statistical Bulletin No. 526.

 of fish to the case, amounted to 3,599.774 cases, valued at $28,867,169, 

 of which 2.596,826 cases, valued at $19,632,744, were packed in Alaska,
