Money: Take one fourth more than your estimated expenses, and a good supply of small change.
Geography: Acquaint yourself with the geography of the route and region of travel.
Luggage: Arrange, if possible, to have only one piece of luggage to look after.
Dress: Better be too hot two or three hours at noon than be cold for the rest of the twenty-four.
Time: Be at the place of starting fifteen minutes before time, thus allowing for unexpected detention by the way.
Breakfast: Do not begin a day’s travel before breakfast, even if it has to be eaten at daybreak. Dinner or supper can be more easily ignored than a good breakfast.
Manners: Respect yourself by demonstrating the manners of a gentleman or lady, and then you will receive the respect of others.
Language: A good knowledge of the language of the country you are to visit is an immense help and will make the journey more agreeable.
Climate: No special considerations may be necessary when travelling to moderate climates or on short journeys, but for longer journeys and to tropical climates it is important to have tropical clothes as part of your hand luggage. The traveller’s comfort depends on his dress being suitable to the climate he is in.
Packing: Always allow ample time for packing. See to it that every piece of luggage is properly labeled and that all labels previously used are removed. The principal point to remember in packing is to leave the things you are most likely to require, during the journey or on arrival, until last. If you carry a handbag, small portmanteau or hold-all, they should be put in these.
Trains: this new mode of transport should not be feared. It is safer to ride on the railroad than to walk through the streets.
It is unwritten law that the passengers occupying the window seats facing the engine have “charge” of the windows. There is no reason why you would not ask one of the window seat passengers if he would object to a window being opened.
Make- up: it is not a correct thing to do to make up while travelling. Many girls prefer not to show too openly how much the rosy of their cheeks owes to art instead of nature. It’s not right for young men to use a comb or nail-file in public places.
Lost: if you are lost, use your watch. Point the hour to the sun and the south is exactly half way between the hour and the figure 12 on the watch. For instance, suppose it is 4 o’clock, point the hand indicating 4 to the sun and 2 on the watch will be exactly south.
Journal : Many experienced voyagers keep a journal while they are travelling. A well-kept journal acts as a remembrance for years to come. Be sure to pack inks, nibs, blotters and note pads.
