470 BULLETIN OF THE UNITED STATES FISH COMMISSION. 



mg fisli. I can get salmon eggs enough next season from the canneries 

 at the mouth of the Columbia to feed my fish very cheaply. So far I 

 have been feeding my trout on eggs from that place, and on liver from 

 Portland. I am satisfied I can raise trout to perfection. I am now en- 

 gaged in making the third pond. 



Klamath Lake, Goose Lake, Back Lake, Crater Lake, Toule Lake, in 

 this vicinity, and many smaller lakes in the Cascade range of mountains, 

 are well calculated to raise large quantities of black bass and whitefish. 

 The black bass particularly would be suitable to stock Toule Lake, Link 

 Eiver, and Lower Klamath Lake, where great quantities of suckers now 

 abound. They would teed on the suckers and cause them to decrease. 

 The black bass would increase very rapidly. 



The German carp is a big, thrifty, bony fish, just like the big Indian 

 suckers which now fill Toule Lake, and which run up Lost Kiver in the 

 spring into Oregon to its head. Jt is a good fish to supply food for the 

 millions on a large and cheap scale; but the salmon, the black bass, 

 grayling, trout, and whitefish, will always command a better price. 



The Oregon legislative assembly has made two or three small appro- 

 priations for a fish ladder at Oregon City. It will take $12,000or $15,000 

 to make a good permanent one, blasted out of the solid rock, and after 

 the McDonald patent. The increase in the Upper Willamette would be 

 worth four times the money in three years. There is no place on the 

 Pacific coast better for salmon than the Willamette above the falls, but 

 not a salmon can now ascend above Oregon City to spawn. The com- 

 pletion of this ladder and the introduction of black bass and whitefish 

 into Oregon would be a lasting benefit to the citizens of Oregon. In 

 time these three things would feed millions of people with the best of 

 food. But few carp will be eaten when there is plenty of salmon, black 

 bass, whitefish, and trout. 



Decrease of Grayling in Au Sable Eiver. — Mr. D. H. Fitz- 

 hugh of Bay City, Mich., writing September 22, 1884, says the graylings 

 put into An Sable river some years ago are about exhausted. It is a 

 very fine trout stream. 



To Destroy Muskrats. — Dr. Hessel has been greatly annoyed by 

 these pests. He has destroyed many. His mode is to suffocate them, 

 as follows: Four pounds of sulphur mixed with half a pound of salt- 

 petre finely pulverized, set on flat stones or a piece of sheet iron, say 

 half a pound, or a pound to a hole (as it costs but a few cents), and 

 placed in the holes; after burning a few minutes, close the holes with 

 sods. The saltpetre insures the combustion of the sulphur, which is 

 certain death to all within. Others have also tried it with success. 



A LARGE Bass from the Potomac. — September 20, 1884, Mr. J. 

 C. Clagett, of Frederick, Md., caught in the Potomac, at Point of Eocks, 

 a small-mouthed black bass, which was shown at the Health OflBce, and 

 measured 23f inches in length, 14| inches around behind the gills, 16| 

 inches at the dorsal fin, and weighed 6 pounds 10 ounces.
