To keep himself up to his business, and stimulate his flagging attention, he should provide himself, before setting out, with a set of queries, so prepared as to include every great class of facts connected with the condition of a people, and so divided and arranged as that he can turn to the right set at the fitting moment.--These queries are not designed to be thrust into the hand of any one who may have information to give. They should not even be allowed to catch his eye. The traveller who has the air of taking notes in the midst of conversation, is in danger of bringing away information imperfect as far as it goes, and much restricted in quantity in comparison with what it would be if he allowed it to be forgotten that he was a foreigner seeking information. If he permits the conversation to flow on naturally, without checking it by the production of the pencil and tablets, he will, even if his memory be not of the best, have more to set down at night than if he noted on the spot, as evidence, what a companion might be saying to him. But a glance in the morning at his list of queries may suggest inquiries which he might not otherwise remember to make; and they will help him afterwards to arrange the knowledge he has gained. He can be constantly adding to them as he goes along, and as new subjects arise, till he is in possession of a catechism on the facts which indicate morals and manners; which must prevent his researches being so capricious, and his information so vague as his moods and his idleness would otherwise occasionally make them. The character of these queries must, of course, depend much on where the traveller means to go. A set which would suit one nation would not completely apply to any other. The observer will do wisely to employ his utmost skill in framing them. His cares will be better bestowed on this than even on his travelling appointments, important as these are to his comfort. When he has done his best in the preparation of his lists, he must still keep on the watch to enlarge them, as occasion arises. Some travellers unite in one the functions of the query list and the journal: having the diary headed and arranged for the reception of classified information. But this seems to be debasing the function of a journal, whose object ought to be to reflect the mind of a traveller, and give back to him hereafter the image of what he thought and felt day by day. This is its primary function;--a most useful one, as every traveller knows who has kept one during a year's wandering in a foreign country. On his return, he laughs at the crudity of the information, and the childishness of the impressions, set down in the opening pages; and traces, with as much wonder as interest, the gradual expansion of his knowledge, education of his perceptions, and maturing of his judgments as to what is before him, as week succeeds to week, and each month mellows the experience of the last.
