which has been recently spun npon the nest. The nature of the open- 

 ing was not learned with precision as I possessed only a single specimen. 

 Tlie vesicle lies to the right side of the intestine, and there is very little 

 doubt but that it opens in front of the anus. The testes are two ovoid 

 glands, the ducts ot which unite into a common canal, both glands and 

 ducts being covered with black pigment cells; they measure something 

 less than an eighth of an inch. As to the origin of the secretion I have 

 no suggestion to make, but there are certain glandular structures lying 

 close by, the significance of which I was at a loss to understand. 



This spinning habit of Apeltes was first noticed by my friend Mr. Seal, 

 who has watched the breeding and nursing habits of these interesting 

 fishes very closely, and it is my hope that I may some time be able to 

 deal more at length with this part of the subject with the help of his 

 notes and beautiful sketches.

A CAI.l, FOR CARP FR07I NEVADA. 

 BY I. D. PASCO. 



This country is the most God-forsaken country in the world — a min- 

 ing camp (silver), and the water small streams from the mountains. The 

 nearest fish are in the Reese Eiver, 30 miles distant. Eeese Eiver would 

 not be called a creek in Pennsylvania; it would be a brook. When I tell 

 you that last winter trout came from Truckee and Walker Rivers em- 

 balmed in snow and ice, and sold for 37i cents per pound, you will see 

 that we have reason to be anxious about the matter. The big thing is 

 to get a good start (to get the fish), get them to breeding and we wiU 

 supply and stock the country. I would give 15 for a pair that are big 

 enough to spawn now. Our waters teem with insect life but not a fish, 

 and I know that fish would live in them although our springs are all 

 warm, and some boiling hot. The water in the streams from the mount- 

 ain, consisting of snow water, sinks sooner or later. I have as a jilace 

 to begin, with a pond — an old channel of this stream (Meadow Creek) 16 

 feet wide, 40 rods long, and 2 feet deep, of i3ure water. I will give you 

 a descrii)tion of a place Mrs. Hathaway, a widow, owns : There are as 

 many as twenty springs rising in a half circle and running a stream 

 about 3 miles, a good step across the stream ; there are fish that never 

 get longer than 3 inches, too small for use. How they ever got there is 

 unknown, for the water does not connect with any place. Here a 

 3-foot dam, 50 yards long, would cover 50 acres. Give us the fish, and 

 we will build reservoirs to hold the snow water, and use for irrigation 

 and fish ponds. The two will work well together. I cultivate the water 

 cress for sale in Belmont; it does well, but the algce (frog spittle) is a 

 great bother in the cress beds. Here are two articles that the cari) 

 would eat; and I believe in the warm springs they would not in the 

 winter be dormant in the mud, but grow all winter.
