  4. Steelyard • A steelyard is a weight used balance two heavy weights. • Lewis & Clark the weight to figure out how much beaver skins and other things weighed.

  5. Powder Keg • In Philadelphia in May of 1803, Lewis ordered 52 lead canisters of gun powder and sealed with wax. • The cork plug is sealed with wax. • Inside the keg was gun powder that the Corps of Discovery needed on the journey. • You had to put the gun powder in the rifle first, then add the lead bullet and push it all down with a steel rod. • Then, when you pulled the trigger, a little spark would light the gun powder and the bullet would shoot out of the rifle.
