06 PRACTICAL CARP CULTURE. 



and as these articles demonstrate is capable of great havoc in ponds where 

 young fish are raised, and in any pond it lives on that which properly 

 belongs to the fish, and should therefore find a home in no fish pond. 



HOW TO GET RID OF THE ENEMIES. 



We have pointed out the means of destroying many of them, and 

 while the ponds are full of water it is impossible to get at the others, 

 such as foreign fish, etc. But when the water is turned off of the ponds 

 and the bottoms lie exposed you have them at your mercy. For thia 

 reason it is well to draw the ponds twice a year, spring and fall, where 

 the water supply is good and they can readily be refilled, otherwise, as 

 we have before said, draw them but once a year and that in the fall when 

 you will have the winter months in which to fill them. To destroy the 

 enemies, when the ponds are empty take quicklime and scatter in such 

 portions of the bottom as is likely to conceal those enemies. Use enough 

 of it to destroy all remaining animal life. Let the pond stand empty for 

 about one week. When the water is again turned on let it stand a few 

 days before putting in the carp. The lime will serve a three-fold pur- 

 pose. First, it will destroy the animal life with which it comes in con- 

 tact. Second, and we believe, almost equally important, by sweetening 

 the bottom of the pond, it will neutralize the poisonous gases, and in 

 part destroy such animal and vegetable matter as generates these gases. 

 If not entirely successful in this latter purpose, we are confident that it 

 will contribute greatly to the aid of the other agencies employed. Third, 

 it will act as a fertilizer, and make the pond more prolific in vegetable 

 growth, which in turn will furnish food for the carp. 



ERRATUM. 



By an accident, the cut on page 54, was run through a part of the edition upside down. 

 This was serious only in the fact that it made a water flea out of the water asell. The cut 

 should have been thus:
