136 NATURE-STUDY REVIEW [14:4— April, 1918 



5. Finally, when everything is ready, put in the fishes. Use 

 small fishes of nearly uniform size. National and state fish com- 

 missions stand ready to supply these on application, and to give 

 advice as to the kinds best adapted to different localities. 



6. Go out and catch your fish, first giving them time to grow to 

 table size, keeping, the while, an eye on the pond to see that every- 

 thing is working properly. The water should be always clear and 

 sparkling by reason of the oxygen continually liberated from the 

 pond weeds. The water meadows should grow dense and full of 

 forage. If pond-scums grow extensively, add a few alga-eating 

 fish, like goldfishes or golden shiners, to keep them down. Once 

 properly set agoing there is little to do with such a pond as this 

 except to catch your fish; and the methods you use in catching 

 them will vary much according as you do it for business or for 

 sport. 



DR. SHUFELDT, A TRUE PATRIOT 



At his own request, Dr. R. W. Shufeldt has been returned to the active 

 list of the Medical Corps of the Regular Army, and has been detailed to the 

 Army Medical Museum, in Washington. Although Dr. Shufeldt is deeply 

 interested in his research work, he feels that now is the time when his country 

 needs the aid of every man and so he has cheerfully given his services.
