swift and pure water. It is a much superior fish for the table than 

 any of the trouts, and in g-anie quahties is their equal. As the 

 species is rapidly disappearing, it seems to be important that so 

 good and beautiful a fish should be preserved by artificial propa- 

 gation, and no reasonable efforts should be spared to determine 

 the conditions best suited to its successful culture. 



Mr. Clark: This work of Dr. Henshell is a matter that I am 

 verv much interested in. In the year 1885 the United States 

 Fish Commission gave me instructions to proceed to the Au 

 Sable River to investigate the spawning of the grayling, and I will 

 say, by the wav, that I kept a report of that trip, and meant to have 

 it here. At that time Mr. Bower was my assistant. He was dis- 

 patched to the Au Sable and we succeeded in obtaining a few 

 grayling eggs. I think there were 25,000 taken to Northville. 

 Of that number, 5,000 were shipped to Washington, and from 

 there sent to Wytheville, Virginia. There was no difficulty in 

 shipping them. The experience we had in hatching them was 

 something different from the Doctor's. We had no trouble about 

 the eggs sticking any more than with trout eggs, and they didn't 

 bunch up after we had them on the trays. They of course adhered 

 slightly, but after you had separated them there was no bunching. 

 We had no difficulty in hatching them ; the difficulty with us was 

 in raising them after they were hatched. The time we used in 

 hatching in a temperature of probably 55 degrees was from four- 

 teen to twenty days. At the time Dr. Henshall was about to com- 

 mence the work I received a letter from my chief, Mr. Ravenel. 

 in Washington, in reference to the Doctor's taking hold of that 

 work, and he asked me what I would suggest as an apparatus 

 for hatching. I suggested the jar if they were to be handled 

 in large quantities. I see the Doctor did try the jar. I don't 

 know whether you gentlemen have seen the young grayling at 

 the Exposition grounds, but when you do I think you will say 

 they are different from the young gra}'ling we hatched in 1883. 



Mr. Bower: At the time we attempted to secure the grayling 

 from tne Au Sable and Manistee Rivers, those streams were liter- 

 ally filled with logs. Of course, the fish at that time of the year 

 Hidn't bite freely, and the only way we could get them was by 

 bottom fishing, using worms or minnows. The opportimities for 

 fishing were limited to occasional open spaces in front of where 

 logs had lodged. We succeeded in getting between 40 and 50 

 adult grayling, none of which were ripe. We held them in crates 

 a few days, until ripe, and in this way secured about 50,000 eggs.
