 economy, and hygienists assure us it is a very serious damage 

 to health. 



Fish supphes the protein which meat furnishes, and which 

 is needed to build the tissues of the body, without the large 

 amounts of fat which are not needed by people of sedentary 

 habits. For brain-workers it seems to be on this account a very 

 useful food.

SOME OBSERVATIONS UPON THE GRAYLING. 



BY J. C. PARKER, OF THE MICHIGAN FISH COMMISSION. 



The question as to whether the grayling ( Thynialliis tri- 

 color) could be successfully propagated artificially being prac- 

 tically undecided by this Commission, it was decided to 

 prepare waters as nearly in accordance with natural conditions 

 as possible and make as careful and systematic an attempt as 

 we could to solve it. Accordingly ponds were made on the 

 Buck Horn creek, of just sufficient depth to admit of screening 

 and through which the whole creek flowed, with the hope 

 that if placed here, they would in the spring — the spawning 

 season — give us an opportunity to observe and handle them, 

 under less difficult circumstances than in their native streams. 

 We hoped that as the Buck Horn had originally been a 

 good grayling stream, it would place at our disposal the 

 most advantageous conditions. The ponds being in readi- 

 ness, the several members of the Michigan Fish Commission 

 proceeded on the 20th of August to the west branch of the 

 Manistee, fifteen miles from the railroad station at Kalkaska, 

 with boats, cans and camp equipage, prepared to make a week 

 of it. The fish were to be captured with rod and line, it 

 having been demonstrated that this was more certain, and the 

 results more satisfactory, than any attempt to use nets of any 

 description. The result was that at the end of the week we 

 had caught and had in excellent condition about one hundred 

 fine specimens. From five to six of these were put into a can,
