Fish Ponds, Washington, D. C. (R. Hessel, Superintendent). 



Tlie entire force of tlie station and an additional laborer were 

 emploj'ed during July in cutting and removing injurious plants from 

 the ponds, which had been introduced by the flood of 1893. This work 

 was continued throughout the summer, but it became evident that the 

 plants and injurious insects accompanying them could not be eradi- 

 cated in this manner, and as the insects were increasing and doing 

 considerable damage to the young fish, it was deemed advisable to use 

 more effective measures. Accordingly, the ponds were laid bare in 

 December and kept dry for three months, during which time the bot- 

 toms were scraped to a depth of 3 inches and all plants and roots not 

 killed by the frost cut out. One of the most injurious j)lants noticed 

 was the cat-tail, the roots of which extend 2 feet under the ground. 

 The only way of eradicating them is to remove every i)article of the 

 root, as cutting the plants off at the surface of the ground does not 

 seem to stop their growth. 



The output of the station consisted of fish from 6 to 8 months old. 

 The ponds were drawn as usual in the fall, and the fish, with the excep- 

 tion of the shad, were counted, sorted, and transferred to Central Sta- 

 tion for distribution by means of cars aisd messeiigers to various parts 

 of the country. Following is a list of the species transferred: 



Leather carp 22, 208 



Scale carp 14, 700 



Blue-scale carp 485 



Tench, yearlings 10,240 



Tench, two years old 1, 040 



Tench. — Owing to tlie increased demand for tench, more attention 

 was paid to the i)roduction of this species, and as a result 11,280 were 

 distributed in the fall of 1894. The spawners were again placed in t\\Q 

 ponds in April, 1895, and all indications point to a large crop at the 

 close of the year.
