1. Men first hunted because they needed food. Later they hunted for sport. Some collected proofs of their skill-tigers' heads, elephants' tusks, stags' antlers.
2.If you wish to be a hunter and a collector of animals, you do not need to kill. There are ways of making u wildlife collection without harm to the animals.
3.A simple and cheap collection is one of animal tracks These are made in plaster of paris. The materials needed are a bag of the plaster, inch-wide strips of cardboard or thin metal, paper clips, and some water
4. Look for animal tracks near almost any brook or lake. Look in damp places along forest trails. If your camp is among trees make a "track trap" near camp: loosen and smooth the earth around a stump or stone and leave food scraps there. A smooth, fine surface means clearer tracks.
5.To "cast" track it in plaster a copy is easy. First make a loop of the cardboard or metal strip large enough to circle the track, and hold the ends together with a paper clip. Second, press the loop gently into the ground around the track, leaving a rim above the ground. Next, prepare a thin mixture of the plaster of paris and water Then pour the mixture over the surface in side the loop.
6.Wait for the cast to set. This may take about half an hour Test with a fingernail or knife point to see that the plaster is really hard. Lift the hard plaster from the ground Remove the or metal ring. When you paper turn the cast over, you will find a negative ofthe track sticking up on the plaster. This negative, like the negative of a film, is the opposite of the real thing where the ground was hollowed, the plaster will have a bump. Brush the loose dirt and any twigs from the plaster
7.Next, as with film, you make a positive This will look exactly like the track on the ground. Cover the whole surface of the nega tive with grease. You may use petroleum jelly for this step. Set the cast down with the flat side beneath. Fit snugly around it a strip of cardboard or metal wider than your first strip. Fasten this loop too with a paper clip Now pour thin plaster again, about an inch deep, to cover all the surface inside the ring The grease will prevent the new plaster from sticking to the negative
8.Remove the ring when the plaster of this second cast has set. Pry the two casts apart. When they separate, this new cast gives a perfect copy of the track as it appeared on the ground the positive of the track
9. lf the casts stick rather than separate you will have to break one of them. You may be satisfied to have a single positive. Or you may break the positive and cast another from the good negative. Sticking is caused either by too little grease or by a rough piece of plaster on the negative locking it to the positive.
10.Mark each cast with the name of the animal, the place, and the date. If you like, paint the cast brown to match the earth. You will have the start ofan interesting and different collection.
