　　The search for latent prints is done in a systematic and intelligent manner. Investigators develop techniques to locate traces of fingerprints at a crime scene. The basic premise in searching for latent prints is to examine more carefully those areas, which would most likely be touched by persons who have been on the scene. The natural manner in which a person would use and place his hands in making an entrance or exit from a building or in handling any object is the key to the discovery of latent prints.

　　Where a forced entrance has been made, latent prints are likely to be found on any surface adjacent to or at that point. Any object with a smooth, non-porous surface is likely to retain latent prints if touched. Fingerprints on rough surfaces are usually of little value. If the fingermark does not disclose ridge detail when viewed under a reading glass, the chances are that its value in identification is nil when photographed. Where fingermarks are found, it will be necessary for the investigator to compare them against the ones of persons having legitimate access to the premises so that the traces might be eliminated as having evidentiary value if they prove to be from these persons. Places to search for prints on an automobile are the rear view mirror, steering wheel hub, steering column, windshield dashboard and the like.

　　Dusting of surface may be done with a fine brush or with an atomizer. The whit powders used are basically finely powdered white lead, talc, or chalk. Another light powder is basically Chemist’s gray. A good black powder is composed of lampblack, graphite, and powdered acacia. Dragon’s blood is good powder for white surface and can be fixed on paper by heating. In developing latent prints, the accepted method is to use the powder sparingly and brush lightly. Do not use powder if the fingermark is visible under oblique lighting. It can be photographed. A good policy for the novice is to experiment with his own prints on a surface similar to the one he wishes to search in order to determine the powder best suited to the surface. Fingerprints after dusting may be lifted by using fresh cellulose tape or commercially prepared material especially designed to lift and transfer dusted latent fingerprints.

　　In addition to latent prints, the investigator must not overlook the possibility of two other types of fingerprint traces: molded impression and visible impression. Molded impressions are formed by the pressure of the finger upon comparatively soft, pliable, or plastic surfaces producing an actual mold of the fingerprint pattern. These can be recorded by photograph without treating the surface, is usually most effective in revealing the impressions clearly. Visible impressions are formed when the finger is covered with some substance which is transferred to the surface contacted. Fingers smeared with blood, grease, dirt, paint, and the like will leave a visible impression. If these impressions are clear and sharp, they are photographed under light without ant treatment. Ordinarily, prints of this type are blurred or smeared and do not contain enough detail for identification by comparison. However, they can not be overlooked or brushed aside without first being examined carefully.

　　Most young people enjoy some form of physical activity. It may be walking, cycling or swimming, or in winter, skating or skiing. it may be a game of some kind football, hockey(曲棍球), golf, of tennis, it may be mountaineering.

　　Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks on high mountains? This astonishment is caused probably by the difference between mountaineering and other　forms of activity to which men give their leisure.

　　Mountaineering is a sport and not a game. There are no man-made rules, as there re for such games as golf and football. There are, of course, rules of a different kind which it would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods. If we compare mountaineering and other more familiar sports, we might think that one big difference is that mountaineering is not ateam game. We should be mistaken in this. There are, it is true, nomatchesbetweenteamsof climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.

　　The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical qualities.

　　A mountain climber continues to improve in skill year after year. A skier is probably past his best by the age of thirty, and most international tennis champions are in their early twenties. But it is no unusual for a man of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they probably climb with more skill and less waste of effort, and they certainly experience equal enjoyment.
