BANDA ORIENTAL AND PATAGONIA 
HAVING been delayed for nearly a fortnight in the city, I was 
glad to escape on board a packet bound for Monte Video. A 
town in a state of blockade must always be a disagreeable place 
of residence ; in this case moreover there were constant appre¬ 
hensions from robbers within. The sentinels were the worst of 
all ; for, from their office and from having arms in their hands, 
they robbed with a degree of authority which other men could 
not imitate.
