of them in about a second; then I waited. Three o'clock came, 

 then four, and no sign of the boys. Some of the pigs would feed 

 while the others stood guard; then they would change off. I was 

 so tired I could scarcely stay in the tree ; so I took my belt off and 

 buckled myself fast to the trunk, so that I would not fall out. 

 Seven o'clock! I could see no change; they still camped near me, 

 showing no signs of weakening. Then the sun went behind the 

 mountain; darkness came on, and I was thirsty, hungry, and tired; 

 but, worse than all, I was a prisoner. Twelve o'clock! The 

 moon shone brightly, and I could see my sentinels scattered 

 around. Two o'clock! Then came a signal from some of the

 was almost always one or two lying in wait near the bathing-place 

 for anything that might turn up at the edge of the water dog,

 in Madagascar, Sibree remarks (in The Great African Island]'. 

 " They are regarded with a superstitious dread by many of the 

 Malagasy tribes, and are so dangerous in some parts of the island 

 that at every village on the banks of the rivers a space is carefully 

 fenced off with strong stakes, so that the women and girls can draw
