40S ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



have been practically done away with. By restoring their 

 original abundance, and even more, and adding the shad, the 

 California salmon, and the Eastern salmon to the number of 

 the inhabitants of the Great Lakes, and introducing the 

 land-locked salmon into the lakes of the interior, the prob- 

 lem of cheap food for the people in Michigan will be meas- 

 urably solved. 



FIRST ANNUAL REPORT OF THE FISH COMMISSIONERS OF 



MINNESOTA. 



The first annual report, for the year 1874, of the State 

 Fish Commissioners of Minnesota has just been printed by 

 order of the Legislature. In this the Commissioners, Messrs. 

 Day, Austin, and Latham, call attention to the great propor- 

 tion of water acreage in Minnesota, and the advantages of 

 the state for fish-culture. According to their calculation, 

 there are, exclusive of Lake Superior and Lake Pepin, and of 

 rivers, no less than 1,601,848 acres of inland lakes alone, or 

 about three and one third acres of water to every hundred 

 acres of land. In addition, the Commissioners claim for the 

 state the existence of some of the most important food fishes 

 of the West, chief among which they consider the whitefish. 

 This is of very great importance to the inhabitants of the 

 state, and nearly 20,000 Indians in Northern Minnesota sub- 

 sist almost exclusively upon it. An account of the measures 

 taken for the disposition of the shad and salmon placed at 

 their command by the United States Fish Commissioner is 

 also presented by them. 



FIFTH REPORT OF THE FISH COMMISSIONERS OF RHODE 



ISLAND. 



The fifth annual report of the Commissioners of Inland 

 Fisheries of Rhode Island, made to the General Assembly in 

 January, 1875, has been published, and contains an account 

 of what has been done by the Commissioners in pursuance of 

 their trust. The efforts of the Commissioners have been 

 largely directed toward restocking the rivers of the state 

 with salmon, of which about 200,000 young were introduced 

 into sundry rivers, particularly the Pawtuxet. Many young 

 salmon were seen in the stream during 1874, and the prospect 

 of success is very encouraging.
