13] EXPERIMENTS IN" PENNING SHAD. 1047 



o-ate on the 23cl. Of this lot 17 females, hard, and 5 males were re- 

 turned to the basin. Six females were found ripe; from 1 of these 

 35,000 good eggs were taken ; from the others nothing but rotten 

 eggs. 



May 26, seine hauled; landed at 10.30. Found one spent shad, the 

 first of the season. Did not put any fish in the basin. 



June 1, seine hauled at 5 p. m. Put 40 females in basin and 8 males 

 in crate. Fish apparently in better condition than any hitherto reserved 

 for penning. In the evening, took 35,000 eggs from female brought in 

 from gillers' boat, dead one hour, and fertilized them with male from 

 crate. Eggs very good, better than any of the 153,000 brought in same 

 evening from gillers' boats. 



June 2, seine hauled; landed at 5 p. m. ; very poor haul; did not 

 put any fish in basin, but placed 4 males in crate. In the evening, 

 hauled seine in basin and caught 35 fish ; found 6 ripe females, but no 

 good eggs ; transferred remainder of fish to boat filled with water, and 

 then taken across line of net extending from gate to gate and over- 

 turned, releasing fish in channel. 



June 5, seine laid out early this morning; landed at 7.30 a. m. 

 Caught 31 shad ; put 7 males in crate and turned remainder of fish 

 over to the men's mess. Lieutenant Low left the station to-day. Seine 

 hauled at 8.30 p. m. ; caught 51 shad, 8 ripe ; took 200,000 eggs. Sent 

 four men out to work the gillers' boats; they took 160,000 eggs; also 

 brought in 4 female shad, from which 100,000 good eggs were obtained 

 after fish had been dead one hour, using live males from the crate. 



June 6, seine laid out at 7 p. m.; landed at 10 p. m. Caught 15 

 shad, 7 riiJe; took 100,000 eggs from five, in the usual manner; took 

 eggs from the other two, and fertilized by cutting open two males and 

 emptying contents of milt sac into a pan, diluting with water, and pour- 

 ing the mixture over the eggs. About 50 per cent of the eggs came 

 up nicely. The males had been stripped in the usual manner a short 

 time before being opened. Caught about 1,000 catfish in the seine. 

 Had a boat fitted up for the purpose* of carrying live fish to and from 

 gillers' grounds ; more especially for towing males out to the men work- 

 ing the gillers' boats, a great scarcity of milters being reported. Boat 

 arranged with holes through sides, covered with netting ; top of boat 

 •covered partly with boards and remaining portion with pieces of seine. 

 In the evening 5 fish were placed in the boat and towed to the gillers 

 near Havre de Grace light. These fish were supposed to be males, but 

 three proved to be female shad. Seventy-five thousand eggs were 

 taken from 3 ripe shad, using the 2 males towed out ; these eggs were 

 the best taken to-day. There were 20,000 taken this evening from other 

 sources, making 195,000 for the day. Making arrangements for put- 

 ting in a pound-net. Went out this afternoon *o drive stakes, but tide 

 was so low could not work launch. 



June 7, wind blowing too hard this morning to drive stakes for
