But, thanks to Dr. Pestle's ample supply of medicine, all kept in excellent health.

VAN'S PERIL.
Jack Howard and his companions were admirably equipped for an overland journey through the African wilds.
It did not take them a great while to outfit Van, the mate and Gregory, the sailor, as well as they were themselves.
Each one of the six wore high top boots, buckskin breeches, and broad-brimmed straw hats. They also carried knapsacks over their shoulders, which were well filled with useful articles.

By the looks of the trail made by the murderer and his followers they must have arrived there fully two days in advance of our friends.
