apparatus yon may have on board the vessel, and by frequently chang- 

 ing the water on them. 



(15) In all of this work of collecting specimens and fish eggs, as well 

 as in the matter of caring for the material, you will be assisted by a 

 specialist, who will join the vessel as soon as practicable. It is now ex- 

 pected that Dr. Tarleton II. Bean will be able to go with you within one 

 or two weeks, and, if circumstances are favorable, it will be well for you 

 to report at Fortress Monroe or Delaware Breakwater, so that he may 

 meet you after you have made your preliminary cruise. 



(1G) Always telegraph your arrival in port, and if you have any val- 

 uable specimens on board wire the facts. Should you obtain any im- 

 portant information relative to the movements or abundance of fish, 

 give all the facts to the Associated Press agent in any port you may 

 visit. 



(17) About the 20th of May you will return to Wood's Holl and take 

 on board the purse seine and seine-boat, after which you will cruise in 

 search of mackerel. If possible, you will surround a school with the 

 seine and take as many live fish in the vessel's well as it may be prac- 

 ticable to carry to Wood's Holl station. The Commissioner deems it 

 very important that we secure a quantity of live mackerel during their 

 spawning season, in order that experiments may be made in artificially 

 propagating that species. 



(18) If you succeed in catching any specimens in your gill-nets, or by 

 hook and line, you will be able to judge pretty accurately as to the 

 development of the ovaries and spermaries in the fish, and you will 

 then know about what is the best time to make preparations for pro- 

 ceeding on your cruise for the same. 



(19) Eeport briefly by mail the results of your work. 

 Very respectfully,

MEMORANDUM TO CAPT. D. E. COLLINS. 



In case you have an opportunity to obtain the livers or oil of various 

 species of fish during your cruise, for instance, such as haddock, pol- 

 lock, cod, menhaden, etc., it is very desirable that specimens of the oil 

 may be saved as pure as possible by trying it out by means of heat or 

 otherwise. Dr. Taylor, of the Department of Agriculture, who has
