officer, in England, has been four and a half
years in the service.      On the completion of seven
years, these men have the option of retiring, on full
pensions.    Some, of course, prove babblers and get
discharged, others, for some large temptation, let
a criminal escape.      The grand requisite for the
office is intelligence, capacity, combined with im-
plicit obedience; for the lower order of men, though
ordinarily faithful are opinionative, wanting to
work up cases in their own way.     The higher
are liable to be bought, as aforesaid, by the men
they are set to trap.        They are all liable to 
be ordered off here, there,
for a thousand miles at a moments warning.  
Money, is all cases, is used freely enough, if
threatened, to hire bravos to counter-threat,
