Observe caution while crossing crowded thoroughfares.
In asking for information, apply to shopkeepers, or to policemen, rather than to passers-by.
The London police are, for the most part, reliable men; and strangers in any doubt or difficulty can generally obtain useful aid from them.
Be on your guard against pickpockets in crowds, street exhibitions, and omnibuses.
Beware of strangers who endeavour to force their acquaintance on you, and affect to be unacquainted with London; they are often low sharpers.
Keep no more cash about you than is needed for the day’s supply.
Be cautious in opening your purse or looking at your watch in the streets.
Avoid low neighbourhoods after dark; if there is anything worth seeing there, see it in the daytime.
Disregard street-beggars; residents only (and not always even they) can tell the deserving from the undeserving.
