TheWasMngton Stations. — The service of the United States carp ponds 

 has been faithfully superintended during the year by Mr. R. Hessel, 

 under whose charge they were originally laid out, and who has had di-

 iceable one, considerable attention has been paid to landscape effects 

 by the proper arrangement of islands and ponds, and also by the in- 

 troduction of plants, which, while having a beneficial relationship to 

 the fish, add to the attractions of the place. The ponds are all very 

 beautiful in their general effect, and in time will doubtless be pre-emi- 

 nent in this regard. 



The water-lily group, especially those belonging to the genera Nym- 

 phwa and Nelumbium, have been particularly cultivated, so that there 

 is quite a large number of rare species represented. 



The advice of Mr. J. F. Olmstead, the landscape engineer, was ob- 

 tained in regard to certain ponds which could be used by skaters. For 

 the purpose of aiding in the means of amusement to the citizens of

 skaters by removing the fish and keeping the water up to the proper 

 level. Some years there is not ice enough to allow this amusement,
