The questions how the condition of the natives, and how the method of observation can affect the final statements have been discussed at length. It was done in order to exemplify how from such considerations may be gathered useful hints, nay even positive indications, as to the direction along which the given statement may be corrected, if corrected at all. There are, besides these points, several other important points referring to the qualifications of the ethnographer that cannot be omitted when any correction of statement is made. There is no room to discuss them in detail; they would lead us too far into the domains of methodology, of ethnographic research. They must be enumerated briefly. So it is quite clear, that not only the personal character but also the profession or occupation of the writer influences very considerably the value and trustworthiness and the character of the information given. The personal character of the ethnographer is a rather delicate matter, but nobody could deny that some authors inspire us with the belief that everything they say is their real conviction, based on solid foundations of facts, while other authors fail to produce the same impression on the reader. It is also clear that a missionary, a police trooper, or an ethnologist, will each look with different eyes upon the same facts; each of them will group the essential features and generalize quite differently, and will express himself in terms which are by no means of the same degree of exactness and clearness. Ultimately each man will have his professional bias: the missionary will be influenced by his creeds and his moral ideas, the ethnologist by his theories, and the squatter or police trooper will sometimes, where there is room for it, allow play to his feelings, which usually are not ones of pure sympathy for the natives. As a matter of fact, it is allowable to speak without exaggeration of professional types of information. That the utmost caution is necessary, and that thus only are to be found indications of the directions in which it is possible to interpret some possible error, is an almost superfluous statement. Of course a careful and complete study of the whole work of an author enables one to judge much better how far his profession or personality may have affected his statements. And this is also the reason why an ethnologist confining himself to a small ethnic area is in a better position than the general one. For he is able to know his sources better, having a much more restricted number to deal with.
