[Abstract. ] 
During tlie period of the shad operations of the steamer Halcyon, 
which commenced on May 2 and ended on the 20th of the same month, 
4.750.000 fry were obtained from the TJ. S. Fish Commission steamer 
Fish Hawk, and from Battery Station, and planted ; and 8,629,000 eggs 
were secured through the agency of gillers. The spawning, which was 
all done at night, was continued until the end of the season. 
On May 11 the steamer Fish Hawk transferred to the Halcyon 
1.250.000 young shad, which, on that date, were planted in the Sassa- 
fras River. 
The Halcyon then proceeded to Beaver Dam, on the Susquehanna, 
the nearest point where successful spawning could be carried on, but 
arrived too late to accomplish anything in that line. 
All the eggs obtained were kept fresh and in good order by means 
of hatching cones and pumps on the vessel, until it was practicable to 
transfer them to Battery Station. 
The following table shows the number of eggs and fry obtained, and 
how disposed of :
