them on board fishing vessels on the grounds. Owing to the cold and 
inclement weather during much of the winter cod were unusually 
scarce and fishing, even under the most favorable circumstances, was 
poorly remunerated. The work of collecting, however, was continued 
whenever opportunity offered until the middle of March. 
Work of the Fish Hawk.—KEarly in January, 1887, the crew and some 
of the hatching apparatus of the vessel were utilized in the work at 
Wood’s Holl. Late in February and till near the end ef March the 
Fish Hawk was engaged in making short trips off Portsmouth and in 
Ipswich Bay, boarding fishing vessels to collect codfish spawn for ship- 
ment to Wood’s Holl. 
d. The Mackerel (Scomber scombrus). 
In the month of May Captain Chester secured three gravid mackerel 
at Wood’s Holl, and from them eggs were taken and placed in the ap- 
paratus which had been used for eggs of the cod. The fish commenced 
hatching in ninety-four hours after the eggs had been placed in the 
jars. This adds another very important species to the list of fishes 
that may be propagated at the Wood’s Holl Station. 
e. The Black Bass (Micropterus dolomici). 
11 breeders and 100 yearlings were collected during the summer at the 
Wytheville Station. 48 vearlings were sent away during the year. 
f. The Red-eye (Ambloplites rupestris). 
At the Wytheville Station, during the fiscal year 1886-87, 77 breeders 
and 2,125 yearlings were obtained. 18 breeders were sent to the Cen- 
tral Station and 2,085 yearlings were distributed, including 586 in 
Cacapon River and 600 in Cowpasture River. On March 1, 1887, 25 
red-eyes, about an inch in length, were sent to Max von dem Borne, 
Berneuchen, Germany, 20 of which reached their destination in safety. 
The red-eye is a good pan fish, gamey, and weighs a half pound on 
the average; it is likely to do well in ponds. 
g. The Sunfish (Lepomis gibbosus). 
During the summer of 1886, 125 sunfish, about 1 inch in length, were 
taken at Cold Spring Harbor and forwarded, through Mr. E. G. Black- 
ford, to Max von dem Borne, Berneuchen, Germany, who was fully ad- 
vised of their predatory character. 
h. The White Perch (occus americanus). 3 
Three shipments of the young of this fish were sent from the Cold 
Spring Harbor Station to Max von dem Borne, in October and Decem- 
ber, 1886, and March, 1887, of which only three, from the last shipment, 
reached Germany alive. 
i. The Rockfish or Striped Bass (Loccus lincatus). 
600,000 eggs were obtained at the Battery Station, near@favre de 
Grace, Md., but owing to pressure with the shad work, few of them were
