XIII.— A FAMILY. BREAKFAST. 

 The borer in the center of the group is the guilty one. Tlie others are 

 late comers, having scented the meal and followed it up. There were six 

 individuals after this one oyster, but two dropped off before the photograph 

 could be taken. The one on the right is in the best position to profit by the 

 meal which another has provided, being at the outer edge of the valves and 

 being able to get as much of the oyster as it needs. It is not uncommon to 

 find groups like this in any place where the borer is found. The borer is very 

 keen scented and will follow an odor, up current, for a considerable distance.
