Whatever plan may be adopted, great care and 

 watchfulness are essentially necessary to insure 

 success. A vegetable parasite, termed by natu- 

 ralists byssus, frequently attaches itself to the 

 eggs, and destroys them. The best way to remedy 

 this evil is to remove very carefully all the eggs 

 that are free from the parasite, and throw those 

 away which have been attacked, and at the same 

 time thoroughly cleanse the boxes or baskets.
