KARROO BEASTS, BIRDS AND REPTILES. 263 



Zul aland an Irish sentry was on guard at midnight, 

 when suddenly, close to him, the ground opened, and 

 out of it rose a ghastly living Jack-in-the-box. The 

 moonbeams shone full on the horrid form, long head, 

 and deadly-pale, calf -like face ; and the man — small
