 the adult pair, five young ones, and a fowl which has been killed 

 by the robber male and brought to the pups at the entrance of 

 the den. Both the hen and the young Jackals were mounted by 

 Mr. ter Meer's father, and are fine pieces of work in each instance,

 source was likewise obtained a sufficient quantity of the sand of 

 the desert from such a place as to insure the selection of the
