Remembrance of these things will help you to find your way by night or in fog when other people are losing themselves. HORSES' TRACKS [Illustration: Walking.] [Illustration: Trotting.] [Illustration: Canter.] [Illustration: _O.H. = Off Hind, etc._ Galloping.] [Illustration: Lame Horse Walking: Which leg is he lame in? _N.B.--The long feet are the hind feet._] These are the tracks of two birds on the ground. One that lives generally on the ground, the other in bushes and trees. Which track belongs to which bird? _Using your Eyes._--Let nothing be too small for your notice--a button, a match, a hair, a cigar ash, a feather, or a leaf might be of great importance, even a fingerprint which is almost invisible to the naked eye has often been the means of detecting a crime. With a little practice in observation you can tell pretty accurately a man's character from his dress. How would you recognize that a gentleman was fond of fishing. If you see his left cuff with little tufts of cloth sticking up, you may be sure he fishes. When he takes his flies off the line he will either stick them into his cap to dry, or hook them into his sleeve. When dry he pulls them out, which often tears a thread or two of the cloth. Remember how "Sherlock Holmes" met a stranger, and noticed that he was looking fairly well-to-do, in new clothes with a mourning band on his sleeve, with a soldiery bearing and a sailor's way of walking, sunburns, with tattoo marks on his hands, and he was carrying some children's toys in his hands. What would you have supposed that man to be. Well, Sherlock Holmes guessed correctly that he had lately retired from the Royal Marines as a sergeant, that his wife had died, and that he had some small children at home. PRACTICE IN OBSERVATION.--_Instructor can take the fingermarks of each girl. Lightly rub the thumb on blacklead or on paper that is blacked with pencil, then press the thumb on paper and examine with magnifying glass. Show that no two persons' prints are alike._ IN TOWN.--_Practice your girls first in walking down a street to notice the different kinds of shops as they pass, and to remember them in their proper sequence at the end._ _Then to notice and remember the names on the shops._ _Then to notice and remember the contents of a shop window after two minutes' gaze. Finally, to notice the contents of several shop windows in succession with half a minute at each. Give marks for the fullest list._
